I'm trying to convert some Xaml to HTML using the .NET XslCompiledTransform and am running into difficulties getting the xslt to match Xaml tags. For instance with this Xaml input:
<FlowDocument PagePadding="5,0,5,0" AllowDrop="True" NumberSubstitution.CultureSource="User" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<Paragraph>a</Paragraph>
</FlowDocument>
And this xslt:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
<xsl:output method="html" indent="yes"/>
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates />
</body>
</html>
</xsl:template>
<xsl:template match="FlowDocument">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="Paragraph" >
<p>
<xsl:apply-templates />
</p>
</xsl:template>
I get this output:
<html>
<body>
a
</body>
</html>
Rather than the expected:
<html>
<body>
<p>a</p>
</body>
</html>
Could this be a problem with the namespace? This is my first attempt at an xsl transform, so I'm at a loss.

Yes, it's a problem with the namespace. All of the elements in your input document are in the namespace http://schemas.microsoft.com/winfx/2006/xaml/presentation. Your template is trying to match elements that are in the default namespace, and it's not finding any.
You need to declare this namespace in your transform, assign it a prefix, and then use that prefix in any patterns that are intended to match elements in that namespace. So your XSLT should look something like this:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:p="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
exclude-result-prefixes="msxsl"/>
<xsl:output method="html" indent="yes"/>
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates />
</body>
</html>
</xsl:template>
<xsl:template match="p:FlowDocument">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="p:Paragraph" >
<p>
<xsl:apply-templates />
</p>
</xsl:template>
