RE: [xsl] Capturing position as a number

[Geert Josten <Geert.Josten@xxxxxxxxxxx>]

Hi Charles,

You can do something like:

<xsl:variable name="currentpos" select="position()"/>

Or:

<xsl:variable name="currentpos" select="count(preceding-sibling::CONDITION) +
1"/>

Your expression:

<xsl:variable name="CurrentCond"><xsl:value-of
select="CONDITION[position()]"/></xsl:variable>

Creates a root tree fragment with all CONDITION elements that are a child of
the context, e.g. the CONDITION element that was matched. I guess the
[position()] predicate is not restricting by the way. When looking for some
OTHERELEM at the same position, do something like:

<xsl:variable name="OtherElem" select="OTHERELEM[position() = $currentpos]"/>

Or perhaps prepend a relative path if it is located elsewhere..

Kind regards,
Geert
