Re: [xsl] Break Point in XML document: XPATH??

[Niko Matsakis <niko@xxxxxxxxxxxxx>]

well, one way that is super slow is:

<xsl:copy-of select="following-sibling::elem2[not (contains 
(preceding-sibling::elem-2, "break"))]"/>
<!-- select all elem2 nodes that are have no preceding sibling that has 
the word break in it -->

a faster way might be:

<!-- create a variable with the index of the word break -->
<xsl:variable name="break-pos">
 <xsl:for-each select="following-sibling::elem2[contains (., "break")]">
    <xsl:value-of select="position()"/>
 </xsl:for-each>
</xsl:variable>

<!-- copy all elem2's that occur before that index -->
<xsl:copy-of select="following-sibling::elem2[position() < 
number($break-pos)"/>

this assumes that only one elem2 contains the word 'break'.
