need help writing xsl for following problem:

the following will be input

<main>
<item>books</item>
<source>A</source>
<destination>B</destination>
<status>yes</status>
</main>

based on the values for source, destination and the text of shipQuery, present in the following xml (stored in c:\)... i will copy the status tag in output.

<shipQuery>
<item source='A' destination='B'>books</item>
<item source='Z' destination='default'>pen</item>
<item source='B' destination='A'>default</item>
</shipQuery>

here a default means dont care. (source/destination/item can be anything)

as we can see my output will be

<main>
<item>pen</item>
<source>A</source>
<destination>B</destination>
<status>yes</status>
</main>

if there is no match in the shipQuery xml,

<main>
<item>pen</item>
<source>A</source>
<destination>B</destination>
</main>

will be my output

how can this be achieved?

Hi,

The following stylesheet

Code: Select all


<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

    <xsl:output indent="yes"/>

     <xsl:template match="/">

         <xsl:if test="not(document('shipQuery.xml')/shipQuery/item[

             (@source=current()/main/source or @source='default') and

             (@destination=current()/main/destination or @destination='default') and

             (.=current()/main/item or .='default')

             ])">

             <main>

                 <xsl:copy-of select="/main/item"/>

                 <xsl:copy-of select="/main/source"/>

                 <xsl:copy-of select="/main/destination"/>

             </main>

         </xsl:if>

     </xsl:template>

</xsl:stylesheet>

applied on a document like

Code: Select all


<main>

    <item>pen</item>

    <source>A</source>

    <destination>B</destination>

    <status>yes</status>

</main>

will give

Code: Select all


<?xml version="1.0" encoding="UTF-8"?>

<main>

   <item>pen</item>

   <source>A</source>

   <destination>B</destination>

</main>

This assumes that there is a shipQuery.xml file in the same folder with the following content:

<shipQuery>
<item source='A' destination='B'>books</item>
<item source='Z' destination='default'>pen</item>
<item source='B' destination='A'>default</item>
</shipQuery>

Best Regards,
George
