I have the following XML file:
<document>
<article>
<head>headline 1</head>
<text>
<paragraph>foo</paragraph>
<paragraph>bar</paragraph>
</text>
<date>
<day>10</day>
<month>05</month>
<year>2002</year>
</date>
<source>some text</source>
<portal>ABC</portal>
<ID number="1"/>
</article>
<article>
<head>headline 2</head>
<text>
<paragraph>lorem ipsum</paragraph>
</text>
<date>
<day>10</day>
<month>05</month>
<year>2002</year>
</date>
<source>another source</source>
<portal>DEF</portal>
<ID number="2"/>
</article>
</document>
Now I'd like to return all nodes of each article that occur after the head node and before the portal node. Therefore I was looking into XPath 2 node comparison (<< and >> operators).
What I have so far is the following, which returns empty:
<xsl:template match="/">
<xsl:copy-of select="/document/article/head/following-sibling::*[. << ./article/portal]"/>
</xsl:template>
Any ideas how to fix that xpath query?

Use:
/*/*/node()[. >> ../head and ../portal >> .]
Here is a complete transformation:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:sequence select="/*/*/node()[. >> ../head and ../portal >> .]"/>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the provided XML document:
<document>
<article>
<head>headline 1</head>
<text>
<paragraph>foo</paragraph>
<paragraph>bar</paragraph>
</text>
<date>
<day>10</day>
<month>05</month>
<year>2002</year>
</date>
<source>some text</source>
<portal>ABC</portal>
<ID number="1"/>
</article>
<article>
<head>headline 2</head>
<text>
<paragraph>lorem ipsum</paragraph>
</text>
<date>
<day>10</day>
<month>05</month>
<year>2002</year>
</date>
<source>another source</source>
<portal>DEF</portal>
<ID number="2"/>
</article>
</document>
the wanted, correct result is produced:
<text>
<paragraph>foo</paragraph>
<paragraph>bar</paragraph>
</text>
<date>
<day>10</day>
<month>05</month>
<year>2002</year>
</date>
<source>some text</source>
<text>
<paragraph>lorem ipsum</paragraph>
</text>
<date>
<day>10</day>
<month>05</month>
<year>2002</year>
</date>
<source>another source</source>
Update:
In a comment Roman Pekar has specified a new requirement: he wants to get all such nodes that are between the first head and portal of each article.
Of course, this is straightforward -- just change the above expresssion to:
/*/*/node()[. >> ../head[1] and ../portal[1] >> .]
A simple XPath 1.0 expression should work for such a case:
/document/article/head/following-sibling::*[following-sibling::portal]
