help with element deletion using xslt

[WideBoy]

Hi,

I have a software generated schema which creates a few empty elements,
e.g. <xsd:sequence/>. I would like to be able to delete these elements
from the schema post-generation using XSLT.

I've tried using the identity pattern to copy the whole schema except
these rogue elements but I seem to be getting stuck on how to
correctly choose this particular 'sequence' element to ignore during
copying.

I would really appreciate some pointers on how I could do this.

regards,

Wideboy

Assuming you've bound the XML Schema namespace to the xsd
prefix in your transformation:

xsd:sequence[not(*)]

Pavel,

Thanks for your advice, unfortunately, being a total novice it did not
work for me.

Here's my input test schema and xslt that I'm using.
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xsd:element name="TestSchema">
<xsd:annotation>
<xsd:documentation>Comment describing your root element</
xsd:documentation>
</xsd:annotation>
</xsd:element>
<xsd:complexType name="VarCharStructure">
<xsd:annotation>
<xsd:documentation>A characteristic that can vary over time. The
time at which the characteristic is recorded is given by the activity
or occurrence of information to which it is linked.</
xsd:documentation>
</xsd:annotation>
<xsd:complexContent>
<xsd:extension base="SuperClassStructure">
<xsd:sequence/>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
<xsd:complexType name="SuperClassStructure">
<xsd:annotation>
<xsd:documentation>Provides a referencable ID element for all class
objects</xsd:documentation>
</xsd:annotation>
<xsd:sequence>
<xsd:element name="SuperClassURN" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>

Processed using this XSLT:
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/

>

<!-- copy through any comments or processing instructions found in
the input schema -->
<xsl:template match="comment()|processing-instruction()">
<xsl:copy/>
</xsl:template>
<!-- copy any other elements and associated attributes and values -->
<xsl:template match="*">
<xsl:if test=".//xsd:sequence[not(*)]"/>
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>

Produces the same output as the input demonstrating my total lack of
understanding of xslt.

best regards,

W.

You simply need

<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xsl:template match="xs:sequence[not(node())]"/>

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

</xsl:stylesheet>

The second template above is the identity transformation template, the
first template ensures that empty xs:sequence elements are not copied.
