Our WinForms based application takes documentation files that were generated by Visual Studio (Xml documentation), performs some XSLT transformation and displays the result in a WebBrowser control inside our form.

Problem is, We cannot seem to get line breaks to be displayed, for example for tags in the xml documentation.

For example:

        <member name="T:Genesys.AgentLoginData">
            <summary>
            This is some test summary <br />
            New line here
            </summary>
        </member>

When used with the XSL transformation, the summary text will be truncated into a single line.

For simplification, the transformation does this for selecting the summary text:

<xsl:template match="member" >
<xsl:value-of select="summary" disable-output-escaping="yes" />
</xsl:template>

How can we properly get new lines to be displayed in the WebBrowser control inside our application?

EDIT: Adding the contents of”View Source” from the WebBrowser control.
What i’m after is a new line after “This is a method”, and so on.
The browser simply displays that in a single line.

<?xml version="1.0" encoding="utf-8"?><html xmlns="http://www.w3.org/1999/xhtml"><head><title>Action Help</title><style type="text/css">
          p  {text-indent:200px;}
          li {text-indent:180px;}
          h1 {color:navy;}
          h2 {color:blueviolet}
          h4 {color:navy;}
        </style></head><body><H2 xmlns="">AgentLogin</H2><H1 xmlns=""></H1><h3 xmlns="">
            This is a method 
            And its parameter 
            Check this out
            name</P></body></html>

    You’re probably looking for xml:space="preserve" directive. See http://msdn.microsoft.com/en-us/library/aa468566.aspx for a decent article on how to handle XSL and whitespace on the .net stack.

    Although I just noticed that you’re displaying the resulting transform in a web browser control, which may mean that your problems actually with the produced HTML. Try viewing source on what you’re displaying in the control and add that to your question.

    Looking at the updated comments, and making some guesses, I think your problem is that you’re using xsl:value-of, which just gets the text of the node, instead of xsl:copy-of, which would get the text of the node, along with the <br/> elements. Try replacing this:

    <xsl:value-of select="summary" disable-output-escaping="yes" />

    with 

    <xsl:copy-of select="summary/node()" />

    Your other option would be to escape the <br/> so that it come through as text instead of a child node, and leave disable-output-escaping on.
