My application reads values from an xml file which I write everytime when I execute the application.
This is how I made comments of my lines:
XmlComment DirCom = doc.CreateComment("Comment")
XmlElementName.AppendChild(DirCom);
And It works fine, But now I need to comment the XML element, And the above doesn't work. My final result should be like:
<!--<name>David</name>-->
using C# and the XML document library.
To comment an xml node I would do it like this :
XmlComment DirCom = doc.CreateComment(XmlElementName.OuterXml);
doc.InsertAfter(DirCom, XmlElementName);
doc.RemoveChild(XmlElementName)

I am new to C# web development. I am developing a software that receives response from webservice in XML format. (includes barcodes generated by webservice).
There is an option given by webservice provider, that i have to add a line
(Example<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">)
as a second line in the xml and display in web browser by using style sheets provided by webservice provider. If i have to choose this option, how can i add that line as second line in the received xml file also how can i map the style sheets provided by the webserive in the project for this xml.
If i dont take that option, Is it possible to display the data in xml as a pdf(includes barcodes generated by webservice), if i dont choose the option .
If I understand your question correctly, you want to:
Add a stylesheet specification to an existing XML
Convert an XML to PDF
1. ADDING A STYLESHEET
There is an option given by webservice provider, that i have to add a line [...] as a second line in the xml and display in web browser by using style sheets
This is done using e.g. Linq, like in this answer.
First of all, I think the example you used, i.e.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
may be inaccurate, as it is the first line of a XSL file (a stylesheet); those kind of files are used to transform an XML into another file (a different XML or an HTML, like in your case). However, you say
using style sheets provided by webservice provider
so my guess is that you already have those stylesheets and you can you use them, rather than creating them yourself.
If so, the line you want to add is like
<?xml-stylesheet type="text/xsl" href="helloWorld.xsl"?>
Let's suppose you already have your XML stored into an XDocument variable named "Document" with its root element being "Root"
var FilePath = "Example.xml";
var Document = XDocument.Load(FilePath);
var Root = XDocument.Descendants("Root").Single();
Then you can add your stylesheet this way, getting a new XML:
var NewDocument = new XDocument(
new XProcessingInstruction("xml-stylesheet", "type='text/xsl'ref='helloWorld.xsl'"),
Root);
2. XML to PDF
There are several ways to do this.
You might parse your XML, retrieve the elements you want to show on your PDF, use a library like iTextSharp to create a specific layout and place their contents on the file.
Or, since you already have an XML and you can transform it to an HTML using an XSL, you can use wkHtmlToPdf.
Let me know if you need more details.
I am writing a console application that generates an XML file that will be consumed by a server job processing application that was written a long time ago. The server app requires a processing instruction: <?JtJob jobname?>. I'm using C# XDocument to generate my xml:
XDocument xml = new XDocument(new XProcessingInstruction("JtJob", "FieldInspection3_Rejected"),
new XElement("Document",
new XElement("DataFile", tempFileName),
new XElement("FormType","Corrected Form Package"),
new XElement("BYOD_RejectComment",reasonForRejection),
new XElement("BYOD_FromTech",techEmail)
)
);
xml.Save(Path.Combine("C:\\Data", DateTime.Now.ToString("yyyyMMdd_HHmmssffff") + "_Rejected.xml"));
For some reason, the server app requires the processing instruction to be on the first line. If my xml file looks like this:
<?xml version="1.0" encoding="utf-8"?><?JtJob FieldInspection3_Rejected?>
<Document>
<DataFile>C:\Windows\TEMP\tmp387F.tmp</DataFile>
<FormType>Corrected Form Package</FormType>
<BYOD_RejectComment>you're ugly</BYOD_RejectComment>
<BYOD_FromTech>example#gmail.com</BYOD_FromTech>
</Document>
Everything works fine. But when it looks like this:
<?xml version="1.0" encoding="utf-8"?>
<?JtJob FieldInspection3_Rejected?>
<Document>
<DataFile>C:\Windows\TEMP\tmp387F.tmp</DataFile>
<FormType>Corrected Form Package</FormType>
<BYOD_RejectComment>you're ugly</BYOD_RejectComment>
<BYOD_FromTech>example#gmail.com</BYOD_FromTech>
</Document>
It errors. My problem is, using the XDocument code above, it generates the second output.
Without loading my generated xml back in as a string and manipulating the string, is there a way for me to tell XDocument to create the processing instruction on the first line?
I know the blame is definitely to be placed on the server app for not accepting valid XML syntax, but my goal is to get this to work, not fix a 20 year old program.
Edit: Thanks! Using the save override preserved the formatting. Didn't make it all one line, but it allowed me to keep the PI on line 1.
Edit 2: Well, that didn't help me either. But I found out what would help me! XDocument.Save() by default outputs UTF8 With BOM. I changed it to without BOM by using XMLTextWriter and that worked.
What if you used the XDocument.Save(String, SaveOptions) method to get an output all on a single line?
So do this instead:
xml.Save(fileName, SaveOptions.DisableFormatting);
This would force the declaration to be onto the first line with the downside of having the entire document on the first line, but if it works for that program then so be it.
You'll want to use a XDocument.Save() overload that allows you to specify formatting options:
xml.Save(Path.Combine("C:\\Data", DateTime.Now.ToString("yyyyMMdd_HHmmssffff") + "_Rejected.xml"),
SaveOptions.DisableFormatting);

I am trying to extract some information using XPath from an XBRL file (eXtensible Business Reporting Language), which is basically just an XML file.
Here is an example file
The file has multiple namespace declarations and these declarations change from file to file, sometimes.
Can you please help to write the XPath to extract the data in the node "dei:EntityRegistrantName", using C#?
I have tried multiple articles on the internet but can't figure this out.
Using this XML Library, I use a simple element get. The library figures out the namespace for me:
XElement root = XElement.Load(file); // or .Parse(string)
var a = root.XPathElement("//dei:EntityRegistrantName");
Console.WriteLine(a.ToString());
The output is (formatted for readability):
<dei:EntityRegistrantName
contextRef="eol_PE8528----1510-K0009_STD_365_20150630_0"
id="id_6568047_FBD9ABEE-63B9-43BD-B87B-EFE7CC59EFB0_1_400001"
xmlns:dei="http://xbrl.sec.gov/dei/2014-01-31">
MICROSOFT CORPORATION
</dei:EntityRegistrantName>
Simply use the query methods available to you with LINQ to XML:
var doc = XDocument.Load(file);
Namespace dei = "http://xbrl.sec.gov/dei/2014-01-31"
var name = (string)doc.Descendants(dei + "EntityRegistrantName").Single();
I am developing window phone 7 application. I am new to the window phone 7 application. I am referring to the following link for XML Serialization & Deserialization.
http://www.codeproject.com/KB/windows-phone-7/wp7rssreader.aspx
In the above link the LoadFromIso() function is used for XML Deserialization. I want to load the xml file after deserialization in the above link. In simple one case we can do this as in the following code. Similar to the following code I want "doc" in the above link. In the following code we can perform the various opeations on the XML file by using LINQ to XML with following statement
doc = XDocument.Load(isfStream);
The complete code is as follows
IsolatedStorageFile isfData = IsolatedStorageFile.GetUserStoreForApplication();
XDocument doc = null;
IsolatedStorageFileStream isfStream = null;
if (isfData.FileExists(strXMLFile))
{
isfStream = new IsolatedStorageFileStream(strXMLFile, FileMode.Open, isfData);
doc = XDocument.Load(isfStream);
isfStream.Close();
}
In the similar way I want the instance of the XDocument after deserializing the object so that I can perform the various operations on the XML file by using LINQ to XML. Can you please provide me any code or link through which I can obtain the instance of the XDocument so that I can load the XML file & perform the various operation on the XML file by using the LINQ to XML ?
The variable doc in your code is an XDocument of the deserialized content.
You can perform your operations on/with doc.
A simple WP7 project demonstrating loading XML using XDocument and LINQ and data binding to a listbox here. As Matt advises the work gets done on your XDocument instance.

I have this kinda interesting requirement.
Typically you use XSLT to transform an XML document. The transformed HTML is viewable in a web browser, this works just great. I am also guessing the browser handles the transformation in memory, because if you view the page source of an xml document with XSLT, you don't see html, only xml.
What I would like to do is the following.
using c#
grab an xml file from the fileSystem....
Load it into some framework object
attach an XSLT stylesheet
output the rendered HTML back to an html file on the file system.
Is this possible.
I don't expect a full answer on the entire solution. Just a push in the right direction would be great :) thanks in advance.
You can use System.Xml.Xsl to do XSLT in C#.
There's an article here: XML transformation using Xslt in C# that explains how - here's the core of it:
XPathDocument myXPathDoc = new XPathDocument(<xml file path>);
XslTransform myXslTrans = new XslTransform();
myXslTrans.Load(<xsl file path>);
XmlTextWriter myWriter = new XmlTextWriter("result.html", null);
myXslTrans.Transform(myXPathDoc, null, myWriter);
(Edit: Note to #John: that code illustrates the basic idea. It doesn't pretend to be production quality.)
So, I found the answer, and pretty quickly... Its all explained here...
http://www.csharpfriends.com/Articles/getArticle.aspx?articleID=63
what if the html is a invaild format xml?
it looks like we can not use xslt?
Any feedbacks?
