Question

I am trying to use XslCompiledTransform in the .NET class library in order to transform an xml string to an Html string. Please consider that I want to use normal strings, not files.

How ca I do this?

It seems that XslCompiledTransform only works with files…

Load() also accepts XmlReader, and Transform() accepts most combinations of XmlReader input, and XmlWriter, TextWriter and Stream as output.

So most typically, you might use a StringWriter for the output, and a XmlReader created from a StringReader for the input.

Full example, no files:

string xslt = @"<xsl:stylesheet version=""1.0"" xmlns:xsl=""http://www.w3.org/1999/XSL/Transform"">
<xsl:output method=""html"" indent=""no""/>
<xsl:template match=""*"">
<p>some html</p>
</xsl:template>
</xsl:stylesheet>", xml = @"<xml>boo</xml>";

var transform = new XslCompiledTransform();
using (var sr = new StringReader(xslt))
using (var xr = XmlReader.Create(sr))
{
    transform.Load(xr);
}

using (var sw = new StringWriter())
using (var sr = new StringReader(xml))
using (var xr = XmlReader.Create(sr))
{
    transform.Transform(xr, null, sw);
    string html = sw.ToString();
}
