Subject: RE: [xsl] Calculation using the position of an element??


Hi,

Ive tried to come up with an XPath solution involving

position()  (one

line)  to produce a certain value using <xsl:value-of

select="......."/>

My Sample XML File

<tgroup cols = "5">
    <colspec colname="col1"/>
    <colspec colname="colspec1"/>
    <colspec colname="col2"/>
    <colspec colname="col4"/>
</tgroup>

I have two different values (say x and y) elsewhere in the

xml doc and I

need to perform a small calculation that I will now outline in
Pseudocode...

If x="colspec1" then
    position1 = 2
If y="col4" then
    position2 = 4
Result= position2 - position1

ie Result=2


  <xsl:value-of select="count(colspec[(_at_)colname =
$y]/preceding-sibling::colspec) - count(colspec[(_at_)colname =
$x]/preceding-sibling::colspec)" />
