Re: Fetch a sequence of nodes from input file

Thanks very much for these ideas. I'm trying to use Martin's solution but I
don't understand the line:
<xsl:copy-of select="$si | $si/following-sibling::item[. &lt;&lt;
$si/following-sibling::item[level &lt;= $si/level][1]]"/>

What does &lt;&lt; or << mean?

T:\ftemp>type rowan2.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="2.0">

<xsl:template match="/">
  <xsl:variable name="tree1" as="element(doc)">
    <doc>
      <a/>
      <b/>
    </doc>
  </xsl:variable>
  <xsl:variable name="tree2" as="element(doc)">
    <doc>
      <a/>
      <b/>
    </doc>
  </xsl:variable>

1/a &lt;&lt; 1/b: <xsl:value-of select="$tree1/a &lt;&lt; $tree1/b"/>
1/a >> 1/b: <xsl:value-of select="$tree1/a >> $tree1/b"/>
1/a is 1/a: <xsl:value-of select="$tree1/a is $tree1/a"/>
1/a is 1/b: <xsl:value-of select="$tree1/a is $tree1/b"/>
1/a &lt;&lt; 2/b: <xsl:value-of select="$tree1/a &lt;&lt; $tree2/b"/>
1/a >> 2/b: <xsl:value-of select="$tree1/a >> $tree2/b"/>
</xsl:template>

</xsl:stylesheet>
T:\ftemp>xslt2 rowan2.xsl rowan2.xsl

1/a << 1/b: true
1/a >> 1/b: false
1/a is 1/a: true
1/a is 1/b: false
1/a << 2/b: true
1/a >> 2/b: false
