XSLT conveniently lets you say how you want that node tree to be created via a syntax that looks like XHTML. This syntax is described in the XSLT spec as "literal result elements". So for example in your stylesheet you can have <img src="{foo}"/> This tells the XSL processor to add an element named 'img' to the result tree, with an attribute named 'src' and a value of the result of evaluating the XPath expression foo. The XPath expression should be in curly braces and should return a string or a node that you want to see the string value of. String values for each node type are explained in the XPath spec. If your source XML is like this: <mydata> <ImageInfo> <Image ID="123" URI="picture.jpg"/> </ImageInfo> </mydata> And your context node was the 'ImageInfo' element, as in the case when you match on it, the XPath expression to get the 'URI' attribute of the 'Image' element that is a child of the context node is quite simply Image/@URI, which you'd put in the curly braces: <xsl:template match="ImageInfo"> <img src="{Image/@URI}"/> </xsl:template> If you have the XSL processor serialize and emit the result tree as XML, you'll see in the output <img src="picture.jpg"/> And if you have it serialize it as HTML, you'll see <img src="picture.jpg"> Happy coding.
