Default XPath help

Hi,

I have a question about how to return element nodes (not only the text) with an XPath query. For example, in the following xml:

<trucks>
<truck color="blue">
<tires>four</tires>
<engine>V-8</engine>
</truck>
<truck color="green">
<tires>four</tires>
<engine>V-6</engine>
</truck>
</trucks>

if I run this XPath query: "//truck[@color='blue']" all I get back is fourV-8, but I really want to get

<truck color="blue">
<tires>four</tires>
<engine>V-8</engine>
</truck>

Does anybody know how I can do this? Or is it even possible with XPath? Maybe I just need to use DOM functions instead? Thanks in advance.

You are getting all the node, you probably need copy-of not value-of. Value-of outputs the concatenated text, copy-of outputs a deep copy:
Code:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
  <xsl:template match="/">
    value-of:<xsl:value-of select="//truck[@color='blue']" /><xsl:text>#x0a;#x0d;</xsl:text>    
    copy-of:<xsl:copy-of select="//truck[@color='blue']" /><xsl:text>#x0a;#x0d;</xsl:text>
  </xsl:template>
</xsl:stylesheet>
