Re: [xsl] creating a temporary document from multiple inputs

Hi David,

I tried this, and the proposed <xsl:variable name="doc"> produces an error.

<xsl:variable name="paths" as="item()*">
  <xsl:sequence select = "($p1,$p2,$p3)" />
</xsl:variable>
<xsl:variable name="doc" as="document-node()*" select="document($paths)/*"/>

Warning: on line 34
  Required item type of value of variable $doc is document-node();
supplied value has item
  type element(). The expression can succeed only if the supplied
value is an empty sequence.
Warning: on line 34 of strip4ilp.xsl:
  The only value that can pass type-checking is an empty sequence.

  value of variable $doc is document-node(); supplied value has item
