How to get styles of an element in AngleSharp - c#

I can't figure out how i can get all computed styles of an element in AngleSharp. Here's what I've tried:
var config = Configuration.Default.WithDefaultLoader().WithCss();
var context = BrowsingContext.New(config);
var document = await context.OpenAsync("A website");
var button = document.QuerySelector("a.random class");
var styles = document.DefaultView.GetComputedStyle(button); // holds null
Can anyone help figure out how this is done? I found this method on their documentation but it doesn't work.

Use SmartMenu with Selenium WebDriver

I have a SmartMenu in a web app which I need to test with Selenium. I can find the root menu items by partial link text but none of the sub menu items can be found.
Has anyone found a way to do this?
Here is my code:
var menu = IEBrowser.DriverInstance.FindElement(By.Id("main-menu"));
var navigate = menu.FindElement(By.PartialLinkText("Navigate"));
navigate.Click();
var offsite = navigate.FindElement(By.PartialLinkText("off-site"));
offsite.Click();
I get a "NoSuchElementException" on line 5.
I also tried:
var menu = IEBrowser.DriverInstance.FindElement(By.Id("main-menu"));
var navigate = menu.FindElement(By.PartialLinkText("Navigate"));
Actions a = new Actions(IEBrowser.DriverInstance);
a.MoveToElement(navigate).Build().Perform();
a.Click();
var offsite = navigate.FindElement(By.PartialLinkText("off-site"));
a.MoveToElement(offsite).Build().Perform();
a.Click();
This also fails on the "offsite" var.
I managed to locate the elements using
var offsite = menu.FindElements(By.TagName("a"))[2];
I don't know why that worked and By.PartialLinkText didn't.

Removing Slide Layouts from Presentation

I have a following code for removing slide layout parts:
var presentation = output.PresentationPart;
var usedSlideLayouts = presentation.SlideParts.Select(it => it.SlideLayoutPart).ToList();
foreach (var sm in presentation.SlideMasterParts)
{
var slideLayoutIds = sm.SlideMaster.SlideLayoutIdList.Elements<SlideLayoutId>().ToList();
var slideLayoutParts = sm.SlideLayoutParts.ToList();
var i = 0;
foreach (var slp in slideLayoutParts)
{
var isUsed = usedSlideLayouts.Any(usl => usl == slp);
if (!isUsed)
{
var slideLayoutId = slideLayoutIds[i];
slideLayoutId.Remove();
sm.DeletePart(slp);
}
i++;
}
}
When i save the presentation after running it my presentation is corrupted (needs to be restored before opening in power point).
From what I saw (by unzipping the pptx) this could be because of the fact that there is only one slide layout but it's internal URI is like 'slideLayout2.xml'. Is there a way to refresh that internal URI?
For anyone wondering I attached a powerpoint in this github issue:
https://github.com/OfficeDev/Open-XML-SDK/issues/218
Your slideLayoutId is the wrong one. The SlideLayoutParts are not necessarily returned in the same order as the SlideLayoutIds.
You can solve this by changing the line
var slideLayoutId = slideLayoutIds[i];
to
var slideLayoutId = slideLayoutIds.Where(sid => sid.RelationshipId == sm.GetIdOfPart(slp)).FirstOrDefault();
This picks the correct slideLayoutId based on the RelationshipId.

How to set Publish Date in Word Document using OpenXML

I have a situation where a user can upload a word document which contains placeholders for certain properties (i.e. in MS Word the user has gone to Insert > Quick Parts > Document Properties and chosen a property). The specific properties I want to support are Title, Author, Company and Publish Date.
Title and Author are set as Package Properties, and Company is set as an Extended File Property. These are set with the below code, which works correctly:
private static void SetDocumentProperties(ReportTemplateModel model, WordprocessingDocument wordDocument)
{
//these properties always exist
wordDocument.PackageProperties.Title = model.Title;
wordDocument.PackageProperties.Creator = model.Author;
wordDocument.PackageProperties.Created = DateTime.Now;
wordDocument.PackageProperties.Modified = DateTime.Now;
//these properties can be null
if (wordDocument.ExtendedFilePropertiesPart == null)
{
wordDocument.AddNewPart<ExtendedFilePropertiesPart>();
}
if (wordDocument.ExtendedFilePropertiesPart.Properties == null)
{
wordDocument.ExtendedFilePropertiesPart.Properties = new Properties(new Company(model.SiteName));
}
else
{
wordDocument.ExtendedFilePropertiesPart.Properties.Company = new Company(model.SiteName);
}
}
My problem is that I can't work out how the set the Publish Date property. I have tried adding it as a Custom File Property using the below code (which is adapted from https://www.snip2code.com/Snippet/292005/WDSetCustomProperty), but this does not work. I've read a few things about setting custom properties, but I'm confused how they're meant to work. I'm also unsure if the Publish Date should actually be set as a custom property, or some other type of property.
var customProps = wordDocument.CustomFilePropertiesPart;
if (customProps == null)
{
customProps = wordDocument.AddCustomFilePropertiesPart();
customProps.Properties = new DocumentFormat.OpenXml.CustomProperties.Properties();
}
var properties1 = new DocumentFormat.OpenXml.CustomProperties.Properties();
//I have tried both of these lines, neither worked.
//properties1.AddNamespaceDeclaration("op", "http://schemas.openxmlformats.org/officeDocument/2006/custom-properties");
properties1.AddNamespaceDeclaration("vt", "http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes");
var customDocumentProperty1 = new DocumentFormat.OpenXml.CustomProperties.CustomDocumentProperty()
{
FormatId = "{D5CDD505-2E9C-101B-9397-08002B2CF9AE}",
PropertyId = 2,
Name = "Publish Date"
};
customDocumentProperty1.Append(new DocumentFormat.OpenXml.VariantTypes.VTLPWSTR { Text = DateTime.Today.ToShortDateString() });
properties1.Append(customDocumentProperty1);
part.Properties = properties1;
What type of property should the Publish Date be set as, and what is the right syntax for setting this?
Update: I have found that Publish Date is a CoverPageProperty which can be created using the below snippet, but I still haven't found how to set it correctly within the document.
var coverPageProps = new DocumentFormat.OpenXml.Office.CoverPageProps.CoverPageProperties
{
PublishDate = new PublishDate(DateTime.Today.ToShortDateString())
};
Adding the below code to my SetDocumentProperties method seems to work. I must admit I don't fully understand the below code, so any explanation would still be welcome. Additionally, if anyone has a solution which doesn't include writing XML as a string inside C# I would much prefer to avoid that.
const string publishDatePartId = "publishDatePart";
var publishDateXmlPart = wordDocument.MainDocumentPart.AddNewPart<CustomXmlPart>("application/xml", publishDatePartId);
var writer = new XmlTextWriter(publishDateXmlPart.GetStream(FileMode.Create), System.Text.Encoding.UTF8);
writer.WriteRaw($"<CoverPageProperties xmlns=\"http://schemas.microsoft.com/office/2006/coverPageProps\">" +
$"<PublishDate>{DateTime.Today.ToShortDateString()}</PublishDate>" +
$"</CoverPageProperties>");
writer.Flush();
writer.Close();
var customXmlPropertiesPart = publishDateXmlPart.AddNewPart<CustomXmlPropertiesPart>(publishDatePartId);
customXmlPropertiesPart.DataStoreItem = new DocumentFormat.OpenXml.CustomXmlDataProperties.DataStoreItem()
{
//I don't know what this ID is, but it seems to somehow relate to the Publish Date
ItemId = "{55AF091B-3C7A-41E3-B477-F2FDAA23CFDA}"
};

XPath to get youtube video c#

The code works, but I can not get the exact link to the page, and that way I do not return anything, it returns an exception that happens because the path does not find anything. The page is as follows, and I need to get the video that this path at the "SelectSingleNode".
please help me to build the correct XPath to get the link of the video from youtube.
My source code:
private void DownloadCompleted(object sender, HtmlDocumentLoadCompleted e)
{
var data = e.Document.DocumentNode.SelectSingleNode("//html/head/link")
.Attributes["href"].Value.ToString();
MessageBox.Show(data);
Uri obj = new Uri(data);
Web.Source = obj;
Web.Visibility = Visibility.Visible;
}
If you click "Inspect Element" on this page, you will find the youtube link that way I describe in "SelectSingleNode". I just left there so you can find the link and help me, but that string is not correct.
This code gets another link. I need to get the real link of youtube video. I try this XPath string but now works: "//html/body/div/iframe/html/head"
There are multiple child LINK elements in the HEAD. You need to identify via the which one you want, similar to this: e.Document.DocumentNode.SelectSingleNode("//html/head/link[#id='someId']")
How about //iframe[contains(#src, "youtube")]//link[#rel="canonical"]?
Returns <link rel="canonical" href="http://www.youtube.com/watch?v=byp94CCWKSI"/>.
I am guessing based off of the method signature that you are using HtmlAgilityPack... which does not retrieve the content of IFrames. You will need to issue a separate request for the content of the IFrame:
var hwMainPage = new HtmlWeb();
var hdMainPage = hwMainPage.Load(#"http://www.unnu.com/jason-derulo/the-other-side");
var iframeUri = hdMainPage.DocumentNode
.SelectSingleNode("//iframe[contains(#src, \"youtube\")]")
.Attributes["src"].Value;
var hwIframe = new HtmlWeb();
var hdIframe = hwIframe.Load(iframeUri);
var videoCanonicalUri = hdIframe.DocumentNode
.SelectSingleNode("//link[#rel=\"canonical\"]")
.Attributes["href"].Value;
// videoCanonicalUri == http://www.youtube.com/watch?v=byp94CCWKSI

Creating an Ektron Smart Form Definition via the API

I've been trying to create a smart form definition from another application. The app successfully creates the smart form, but I'm unable to get the FieldList, DisplayXSLT or Schema fields to populate.
This leaves me with a blank smart form definition (less that ideal).
Here's the code I have to perform the action. Any ideas?
// form is a simple POCO with values copied from an existing SmartForm Definition
var config = new SmartFormConfigurationData();
config.SmartformTitle = form.Name;
config.SmartformDescription = form.Description;
config.XmlSchema = form.Schema;
config.PackageDisplayXslt = form.Xslt;
config.FieldList = form.FieldList;
config.Type = EkEnumeration.XmlConfigType.Content;
var api = new SmartFormConfigurationManager(ApiAccessMode.Admin);
api.RequestInformation.ServicesPath = this.EktronServiceHost;
api.RequestInformation.AuthenticationToken = this.GetAdminAuthToken();
api.Add(config);
Update:
I heard back from Ektron Support on this issue. It's not so much a "bug" per-se... It's more a case of this API class looking very similar to the ContentManager but not behaving like it. I expected that since it looked so similar to ContentManager and many of the other classes, I would be able to call Add() and it would just magically work. It turns out the solution is a little more complicated.
Adding a smartform is a two-step process: first Add(), then Update().
The Add method doesn't set all of the fields and in fact passes in NULL for a few of the parameters on the stored procedure that creates the entry in xml_collection_tbl.
The real fun comes in step 2. Basically, you start with the SmartForm's HTML -- the stuff you see when you're in the "Data Design" view for editing the smart form definition and you click that <> button ("HTML") at the bottom of the editor. You run that through a whole bunch of XSLTs that are burried in the WorkArea folder to construct the missing fields, and then you call update. Here's the code that worked for me:
var sfManager = new SmartFormConfigurationManager();
var data = sfManager.GetItem(12);
if (data == null) return;
var sfcData = new SmartFormConfigurationData();
sfcData.Type = EkEnumeration.XmlConfigType.Content;
sfcData.SmartformTitle = "SmartForm12 copy";
sfcData.SmartformDescription = "SmartForm12 copy";
sfcData.XmlSchema = "";
sfcData.PackageDisplayXslt = data.PackageDisplayXslt;
sfcData.FieldList = data.FieldList;
sfcData = sfManager.Add(sfcData);
Response.Write("SmartForm added with id: " + sfcData.Id);
var design = System.IO.File.ReadAllText(Server.MapPath("~/NewsArticleSmartForm.html"));
var contentApi = new ContentAPI();
var schema = contentApi.TransformXsltPackage(design, Server.MapPath("~/WorkArea/ContentDesigner/DesignToSchema.xslt"), true);
var fieldList = contentApi.TransformXsltPackage(design, Server.MapPath("~/WorkArea/ContentDesigner/DesignToFieldList.xslt"), true);
var viewEntryXslt = contentApi.TransformXsltPackage(design, Server.MapPath("~/WorkArea/ContentDesigner/DesignToEntryXSLT.xslt"), true);
var xsltArgs = new XsltArgumentList();
xsltArgs.AddParam("srcPath", "", "/WorkArea/ContentDesigner/");
var viewXsltSource = string.Concat("<root>", design, "<ektdesignpackage_list>", fieldList, "</ektdesignpackage_list></root>");
var viewXslt = contentApi.XSLTransform(viewXsltSource, Server.MapPath("~/WorkArea/ContentDesigner/DesignToViewXSLT.xslt"), true, false, xsltArgs, false);
var initialDocument = contentApi.TransformXsltPackage(design, Server.MapPath("~/WorkArea/ContentDesigner/PresentationToData.xslt"), true);
var sbPackage = new StringBuilder("<ektdesignpackage_forms><ektdesignpackage_form><ektdesignpackage_designs><ektdesignpackage_design>");
sbPackage.Append(design);
sbPackage.Append("</ektdesignpackage_design></ektdesignpackage_designs><ektdesignpackage_schemas><ektdesignpackage_schema>");
sbPackage.Append(schema);
sbPackage.Append("</ektdesignpackage_schema></ektdesignpackage_schemas><ektdesignpackage_lists><ektdesignpackage_list>");
sbPackage.Append(fieldList);
sbPackage.Append("</ektdesignpackage_list></ektdesignpackage_lists><ektdesignpackage_views><ektdesignpackage_view>");
sbPackage.Append(viewEntryXslt);
sbPackage.Append("</ektdesignpackage_view><ektdesignpackage_view>");
sbPackage.Append(viewXslt);
sbPackage.Append("</ektdesignpackage_view></ektdesignpackage_views><ektdesignpackage_initialDocuments><ektdesignpackage_initialDocument>");
sbPackage.Append(initialDocument);
sbPackage.Append("</ektdesignpackage_initialDocument></ektdesignpackage_initialDocuments></ektdesignpackage_form></ektdesignpackage_forms>");
sfcData.PackageXslt = sbPackage.ToString();
sfcData.FieldList = fieldList;
var baseFilename = "SmartForm" + sfcData.Id;
var schemaFilename = "/" + baseFilename + "Schema.xsd";
var xsltFilename = "/" + baseFilename + "Xslt.xslt";
sfcData.XmlSchema = schemaFilename; // The file will be prefixed with /XmlFiles
var unPackDisplayXslt = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\"><xsl:output method=\"xml\" version=\"1.0\" encoding=\"UTF-8\" indent=\"yes\"/><xsl:template match=\"/\"><xsl:choose><xsl:when test=\"ektdesignpackage_forms/ektdesignpackage_form[1]/ektdesignpackage_views/ektdesignpackage_view[2]\"><xsl:copy-of select=\"ektdesignpackage_forms/ektdesignpackage_form[1]/ektdesignpackage_views/ektdesignpackage_view[2]/node()\"/></xsl:when><xsl:otherwise><xsl:copy-of select=\"ektdesignpackage_forms/ektdesignpackage_form[1]/ektdesignpackage_views/ektdesignpackage_view[1]/node()\"/></xsl:otherwise></xsl:choose></xsl:template></xsl:stylesheet>";
var displayXslt = contentApi.TransformXsltPackage(sbPackage.ToString(), unPackDisplayXslt, false);
System.IO.File.WriteAllText(Server.MapPath("~/XmlFiles" + xsltFilename), displayXslt);
sfcData.Xslt1 = xsltFilename; // The file will be prefixed with /XmlFiles
sfcData.DefaultXslt = 1;
sfManager.Update(sfcData);
I extracted the HTML for my existing smart form and saved in the root of my site as NewsArticleSmartForm.html. Here's what my file looked like:
<p>Author: <input type="text" name="Author" id="Author" ektdesignns_caption="Author" ektdesignns_name="Author" title="Author" ektdesignns_indexed="false" ektdesignns_nodetype="element" size="24" class="design_textfield" /></p>
<p> </p>
<p>Article Summary: <textarea name="Summary" id="Summary" ektdesignns_caption="Summary" ektdesignns_name="Summary" title="Summary" ektdesignns_indexed="false" ektdesignns_nodetype="element" cols="40" rows="3" class="design_textfield"></textarea>
</p>
<p> </p>
<p>Article Body:</p>
<p> </p>
<ektdesignns_richarea id="Body" name="Body" ektdesignns_caption="Body" ektdesignns_name="Body" title="Body" ektdesignns_indexed="false" ektdesignns_nodetype="element"> </ektdesignns_richarea>
<p> </p>
Good luck!
Original Answer:
Creating a copy of a SmartForm configuration should be fairly straight-forward. The SmartFormConfigurationData object has a Clone() method on it which makes it really easy to create a copy of an existing SmartForm. I say "should be" because it doesn't work.
I had an answer all typed out ready to post; I tried some code and it appeared to work. The new smartform was listed in the workarea, but when I clicked on that new smartform to view its details, I realized something was wrong.
I tried the following code:
var sfManager = new SmartFormConfigurationManager();
var config = sfManager.GetItem(7);
if (config == null) return;
var newSmartForm = config.Clone();
newSmartForm.SmartformTitle += " copy";
sfManager.Add(newSmartForm);
Here are the details from the original smartform:
And here's what the new smartform looked like -- the one I created with the frameworkAPI:
I did find one API method that successfully created a copy of an existing smartform:
var sfApi = new Ektron.Cms.ContentAPI();
var newId = sfApi.ReplicateXmlConfiguration(7, "copied sf title");
The problem with that method is that the smartform must exist on your system and you can only change the title. So, I went digging into the database to see what was happening. It turns out that after calling this ReplicateXmlConfiguration() method, the two database records are identical (except for the expected LastUpdated type of fields).
After calling the frameworkAPI's Update() method (same holds true when calling Add()), the "updated" record is clearly different.
I think we've got a genuine bug here. This happens both in v8.7 sp2 and v9.0 sp1. I've opened a case with Ektron support, and I'll update my answer as I hear back. They have always been very responsive when I've dealt with them in the past.
