Why it doesn't work?

What am I not seeing here?

I am used to declare and use variables in XSLT all the time but for any reason this simple thing is not working and I am not managing to see what is wrong with it:

Code:

<?xml version="1.0" encoding="UTF-8" ?>
<package debug="false">
  <PackageTransform>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:aspdnsf="http://www.DNSF2.com">
      <xsl:output method="html" omit-xml-declaration="yes" />
      <xsl:template match="/">
        Testing...<br/>
        <xsl:variable name="foo" select="foobah" />
        My foo value is = <xsl:value-of select="$foo" />
      </xsl:template>
    </xsl:stylesheet>
  </PackageTransform>
</package>

Does your input XML have an element called <foobah>?

Ouch, never mind, my bad.

I supposed to do it instead:

Code:

<xsl:variable name="foo" >foobah</xsl:variable>

I stayed the whole morning over that, and simply didn't see what I was doing.

What you were probably wanting to do was this:

Code:

<xsl:variable name="foo" select="'foobah'"/>

That creates a variable $foo and assigns it the string 'foobah'. What you has previously was missing the single quotes, so was looking for an element called <foobah> and taking its textual value.

Cool, yeah, that's exactly what I had in mind! Thank you again, Sam!
