RE: [xsl] Variable with node list...

That parser is probably right :) <xsl:for-each> needs node-set to iterate through, whereas you give it result tree fragment instead.

Yeah, it seems to me all of us have to try to do it once in the life.

This variable actually holds result tree fragment, not node-set, see http://www.w3.org/TR/xslt#section-Result-Tree-Fragments.

I know 2 ways to resort:
1. use msxsl:node-set(rtf) extension function (see more in msxml doc) to convert result tree fragment to node-set.
2. Redesign you stylesheet this way:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:user="http://user.com/ns";>
  <user:properties>
    <property>one</property>
    <property>two</property>
    <property>three</property>
  </user:properties>
  <xsl:template match="root">
    <foo>
      <xsl:for-each select="document('')/*/user:properties/property">
        <bar>
          <xsl:value-of select="."/>
        </bar>
      </xsl:for-each>
    </foo>
  </xsl:template>
</xsl:stylesheet>
