Filtering out from a node set

anothervbaddict · May 22nd, 2007, 08:33 AM

How do I restrict a collection of data, excluding elements held by another node set?

Main XML Document

Code:

<premount row="14">
    <det_code>ABA</det_code>
</premount>
<premount row="21">
    <det_code>DAA</det_code>
</premount>

(further inside the document)

Code:

<result>
    <det_code>YTY</det_code>
    <cust_code>Customer A</cust_code>
</result>
<result>
    <det_code>DAA</det_code>
    <cust_code>Customer A</cust_code>
</result>

My failing XSL snippet

Code:

<xsl:for-each select="//result[cust_code='Customer A'][det_code=not(//premount/det_code)]">

(I'm expecting <premount row="21"> to be excluded)

Code:

</xsl:for-each>

I've tried:

Code:

[not(det_code=//premount/det_code)]

Code:

[det_code!=//premount/det_code]

Thanks in advance,
Carl

This one (which you said you tried) is correct:

[not(det_code=//premount/det_code)]
