Help needed to write an XSL - XML to XML transformation

2 Possible ways:
1. Change your key such that it takes something unique form the document element containing the attribs.

eg:
<xsl:key name = "kkk" match = "attribs/attrib" use = "concat(..\preceding-sibling::xp,'-',@name)" />

Other work required when using the keys.
-----

2. Change the xpaths eg:
<first_page>
<xsl:value-of select = "attribs/attrib[@name='pg_from_hostdoc']" />
</first_page>

I think the 2nd way is much easier.

Hi ,

Thanks for your suggestion .

After some long trial and errors, I finally found the right XSL code :

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:npl="http://www.epo.org/npl" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:output method="xml" doctype-system="npl-entities.dtd"/>

<xsl:template match = "/" >

<nplbiblio>
<xsl:attribute name="xsi:noNamespaceSchemaLocation">npldoc v2.0.xsd</xsl:attribute>
<xsl:attribute name="rundate">20080123</xsl:attribute>

<xsl:for-each select="nplbiblio/document">


<document status="n">
<xsl:attribute name="creadate">20080123</xsl:attribute>
<xsl:copy-of select="xp"/>
<xsl:copy-of select="doctype"/>
<xsl:copy-of select="prdate"/>
<xsl:copy-of select="xp"/>
<xsl:copy-of select="author"/>
<xsl:copy-of select="supplier"/>

<title>
<xsl:value-of select="titles/title"/>
</title>

<isbn>
<xsl:value-of select="publication/irn/isbn"/>
</isbn>

<issn>
<xsl:value-of select="publication/irn/issn"/>
</issn>


<first_page>
<xsl:value-of select="attribs/attrib[@name='pg_from_hostdoc']"/>
</first_page>

<issue>
<xsl:value-of select="attribs/attrib[@name='nr_hostdoc']"/>
</issue>

<volume>
<xsl:value-of select="attribs/attrib[@name='vol_hostdoc']"/>
</volume>


</document>
</xsl:for-each>
</nplbiblio>
</xsl:template>

</xsl:stylesheet>
It works perfect !!

Thanks again
