On another thread about using XSLT to list every node in an XML file, Alejandro offered this useful piece of XPath 2.0 code:
EDIT: my stylesheet below now uses the modified version of the code that Alejandro kindly posted in a comment. It reports the @name attribute of elements.
I have heavily modified it to apply to a .xsd schema like the following:
Example Schema
(a simplified version of this source)
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:annotation>
<xsd:documentation xml:lang="en">
Purchase order schema for Example.com.
Copyright 2000 Example.com. All rights reserved.
</xsd:documentation>
</xsd:annotation>
<xsd:element name="comment" type="xsd:string">
<xsd:annotation>
<xsd:documentation>doc for comment</xsd:documentation>
</xsd:annotation>
</xsd:element>
<xsd:complexType name="USAddress">
<xsd:annotation>
<xsd:documentation>doc for USAddress</xsd:documentation>
</xsd:annotation>
<xsd:sequence>
<xsd:element name="name" type="xsd:string"/>
<xsd:element name="street" type="xsd:string"/>
<xsd:element name="city" type="xsd:string"/>
<xsd:element name="state" type="xsd:string"/>
<xsd:element name="zip" type="xsd:decimal"/>
</xsd:sequence>
<xsd:attribute name="country" type="xsd:NMTOKEN" fixed="US"/>
</xsd:complexType>
<!-- Stock Keeping Unit, a code for identifying products -->
<xsd:simpleType name="SKU">
<xsd:annotation>
<xsd:documentation>doc for SKU</xsd:documentation>
</xsd:annotation>
<xsd:restriction base="xsd:string">
<xsd:pattern value="\d{3}-[A-Z]{2}"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:schema>
My XSLT Stylesheet:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsl:template match="*|@*">
<xsl:value-of select="
string-join(
distinct-values(
(//*|//@*)
/string-join(
(ancestor::node()/name(),
if (self::attribute())
then concat('@',name())
else if (self::*[@name])
then concat(name(),'[@name="',@name,'"]')
else name()),
'/')),
'
')
"/>
</xsl:template>
</xsl:stylesheet>
Results:

/xsd:schema/xsd:simpleType/xsd:restriction/xsd:pattern/@value
This output is fine, for the purposes of this question.
Now, rather than asking “what’s wrong with my fugly code?” I’ll just ask the best way to proceed from a base state that actually works.
I need to add a clause that, for every line with a /xsd:documentation grandchild, appends the text from <xsd:documentation>foo</xsd:documentation>. So this line:
/xsd:schema/xsd:element[@name="comment"]
becomes:
/xsd:schema/xsd:element[@name="comment"] | doc for comment
Thanks,
Matt
The solution is simple:
.1. Define the
xsdnamespace in your stylesheet:.2. Change:
to
BTW, this is wrong:
There is no element named
xsdin the document. Probably you want:Also, there is no need to use
local-name()on attributes, justname()is OK.Second observation:
There is nothing wrong with Alejandro’s solution. Applied to the provided XML document it produces the following correct output:
