Question

I have, this xml lookup table:

<lookup>
<Codes>
<code>123<code>
</Codes>
<Codes>
<code>321<code>
</Codes>
</lookup>

and document:

<document>
<header>
<remarks>test</remarks>
</header>
<Line>
<Line-Item>
<code>123</code>
</Line-Item>
<Line-Item>
<code>444</code>
</Line-Item>
<Line-Item>
<code>321</code>
</Line-Item>
</Line>
</document>

There is possible, to check document codes with lookup table codes, and if document code=lookup code, delete Line-Item from document.

answer should be:

<document>
<header>
<remarks>test</remarks>
</header>
<Line>
<Line-Item>
<code>444</code>
</Line-Item>
</Line>
</document>

I’m stuck on xsl:stylesheet version=”1.0″.
Best regards 🙂

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:variable name="vCodes" select=
 "document('file:///c:/temp/LookupDelete.xml')/*/*/code"/>

 <xsl:template match="node()|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match=
 "Line-Item[code
           = document('file:///c:/temp/LookupDelete.xml')
                  /*/*/code
           ]
 "/>

 <xsl:template match=
  "Line[not(Line-Item/code
              [not(. = document('file:///c:/temp/LookupDelete.xml')
                               /*/*/code
                   )
              ]
           )
       ]
  "/>
</xsl:stylesheet>

when applied on the provided XML document:

<document>
    <header>
        <remarks>test</remarks>
    </header>
    <Line>
        <Line-Item>
            <code>123</code>
        </Line-Item>
        <Line-Item>
            <code>444</code>
        </Line-Item>
        <Line-Item>
            <code>321</code>
        </Line-Item>
    </Line>
</document>

produces the wanted, correct result:

<document>
   <header>
      <remarks>test</remarks>
   </header>
   <Line>
      <Line-Item>
         <code>444</code>
      </Line-Item>
   </Line>
</document>

If the document is this:

<document>
    <header>
        <remarks>test</remarks>
    </header>
    <Line>
        <Line-Item>
            <code>123</code>
        </Line-Item>
        <Line-Item>
            <code>321</code>
        </Line-Item>
        <Line-Item>
            <code>321</code>
        </Line-Item>
    </Line>
</document>

then again the correct result is produced (note that no Line element is output at all):

<document>
   <header>
      <remarks>test</remarks>
   </header>
</document>
