I am using C# code in aspx pages to covert the infopath xml pages into html. Here is my code:
XPathDocument myDoc = new XPathDocument(#"C:\Users\rameshgandhik\Documents\infopath forms\ram.xml");
XmlTextWriter myWr = new XmlTextWriter(#"C:\Users\rameshgandhik\Documents\infopath forms\ram.html",null);
XslTransform myXsl = new XslTransform();
myXsl.Transform(myDoc, null, myWr); // Here i am getting an error.
At myWr in Transform method it is showing an error that
"No stylesheet was loaded.".
Can any have the idea about this error......... Please tell me the solution....
That would be because you haven't loaded the stylesheet. :-)
You've created a new XslTransform object, but you didn't actually put any transformation rules into it. Therefore, it doesn't know how to transform the XML you're giving it, which is pretty clearly expressed in the error message.
If you want to take the transform from an *.xsl file, you can use the XslTransform.Load method.
If you want to get the transform from some other location, please specify what that location is, and I would probably be able to help you.

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 have a xml structure stored in XDocument.
I want to present as html document (or something similar) , main idea that a web browser will be able to present it .
Does XSLT will right technology here ?
Is there some examples for how to do so ?
Thansk for help.
Yes, XSLT is good for this. I recently had to do this using the following code:
var xslt = new XslCompiledTransform(true);
xslt.Load(styleSheetFile, XsltSettings.TrustedXslt, new XmlUrlResolver());
xslt.Transform(xmlFile, outputFile);
You can use XSLT or LinqToXML. Many examples out there but you can start # http://msdn.microsoft.com/en-us/library/bb387098.aspx
I am using C# 2.0 and I have got below code:
XmlDocument doc = new XmlDocument();
doc.LoadXml(GetListOfPagesInStructureGroup(m_Page.Id));
In above I am loading my XMLDocument with method which returns as string, now after some processing on above xmldocument I want to apply XSLT on the above XMLDocument to render my desired result according to XSLT and finally my function will return whole rendered XML as string
Please suggest!!
Please suggest on below solution:
XslCompiledTransform xslTransform = new XslCompiledTransform();
StringWriter writer = new StringWriter();
xslTransform.Load("xslt/RenderDestinationTabXML.xslt");
xslTransform.Transform(doc.CreateNavigator(),null, writer);
return writer.ToString();
Thanks!!
Try the XslCompiledTransform class.
There are lots of examples on the web of transforming an XML file to a different format using an XSLT file, like the following:
XslTransform myXslTransform = new XslTransform();
XsltSettings myXsltSettings = new XsltSettings();
myXsltSettings.EnableDocumentFunction = true;
myXslTransform.Load("transform.xsl");
myXslTransform.Transform("input.xml", "output.xml");
However this is only a partial answer, I would like to be able to get the XML input data from a web form and use that as the input data instead of an '.xml' file, but have not found any concrete examples, also using Visual Studio I can see the different constructors and methods that are available and I am not seeing one that accepts xml data in a string format, so it would be very helpful if someone could provide an example of that.
Re " I want my same XMlDocument updated " - it doesn't work like that; the output is separate to the input. If that is important, just use a StringWriter or MemoryStream as the destination, then reload the XmlDocument from the generated output.
Consider in particular: the output from an xslt transformation does not have to be xml, and also: the xslt is most likely using the node tree during the operation; changing the structure in-place would make that very hard.
I have an XML file and I have an XSL translator file that came with it which can be used to translate the XML file into an xml file using the NAXML standard format. For some reason, though, I am getting an exception when I call the Load function in the XslCompiledTransform
using System.Xml.Xsl;
Problematic block of code:
XslCompiledTransform xlstProcessor = new XslCompiledTransform();
XsltSettings settings = new XsltSettings();
settings.EnableScript = true;
System.Xml.XmlReader reader = System.Xml.XmlReader.Create("C:\\tlog2naxml.xslt");
System.Xml.XmlResolver resolver = new System.Xml.XmlUrlResolver();
xlstProcessor.Load(reader, settings, resolver); //Exception occurs here.
xlstProcessor.Transform(#"C:\vperiodrept.xml", #"C:\test.xml");
I have tried different variations of these parameters but I keep getting this exception. When I look at the definitions for the XslCompiledTransform class, I do not see any duplicate method signatures. This is a standard .net class so I wouldn't expect to find any. If anyone has any ideas what might be causing this I would greatly appreciate the help.
The problem is with the scripts in the XSLT you're loading, not with the XslCompiledTransform class; this exception's thrown when the compiler is compiling the scripts in the transform, and it's encountering two methods in the script that have the same signature. The first thing I'd look at is includes - I don't know for certain, but I'd bet the compiler's probably not smart enough to recognize when you've included the same file twice.
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...

what if the html is a invaild format xml?
it looks like we can not use xslt?
Any feedbacks?
