Marc FeickertSubject: finding a list of values
Author: Marc Feickert

I need to pull back multiple elements based on an @id attribute which is different for eahc of them. Essentially, given docs numbered 1-10, I want to extract only 3,6,7.

I could grab each by setting my loop in the following way:

<xsl:for-each select="Documents/Document[@id='3' or @id='6' or @id='7']">
<xsl:copy-of select="."/>
</xsl:for-each>


Is ther a more concise way to write the XPath here to where all I need list are the values themselves? Like in SQL where you can say:

SELECT * from DOCUMENT where ID in (3,6,7)

Hi Mark,


In XSLT 2.0 (Saxon 9.x) you can do

<xsl:for-each select="Documents/Document[@id=(3,6,7)]">

In pure XSLT 1.0 could build xml document like this, call it ids.xml

<?xml version="1.0"?>
<ids>
<id>3</id>
<id>6</id>
<id>7</id>
</ids>

and then

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:variable name="ids" select="document('ids.xml')/ids/id"/>

<xsl:template match="/">
<xsl:for-each select="Documents/Document[@id=$ids]">
<xsl:copy-of select="."/>
</xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Hope this helps

Ivan, I am crying for the beauty of it. I had tried that syntax, but i was in XSLT 1.0.

It now works! thanks

Rashi, I have no idea why I did not get notification about this. Do you still have some questions?

Can this approach be adapted to a use case where a list of unique values must be determined from a document content, eg, find and use a list of distinct values from //SOMELEMENT/@SOMEATTRIBUTE, and then used to process all nodes within the set for a given one of the values?
