RE: fairly complex xslt not giving errors I can under

The error is actually not complex at all. If you look at the error's
line number and source code:
Line Number 7953, Column 14:</xsd:schema>g"
-----------------------------------------^

There's just a typo in the XML. Could be either in the source
(mddl-3.0-test.xml) or in the output from the transformation. In either
case, just look for a stray "g" character, and delete it.

As far as your Xalan error goes, ends-with() is a function from XPath
2.0, not present in XPath 1.0. The workaround is fairly simple, change:
  ends-with(@ref, '.children')
to:
  substring(@ref, string-length(@ref) - 8) = '.children'

Hope that helps.

Hi,

I have the following to transform a XSD that is a standard for market
data ( mddl.org)

<?xml version="1.0" encoding="ISO-8859-1"?>

    <xsl:template match="/">
        <xsl:choose>
          <xsl:when test="//xsd:group[ends-with(@ref, '.children')]">
            <!-- We find the group element this refers to and write out
the elements as a part of this complexType -->
            <xsl:variable name="elementName" select="@name"/>
            <xsl:for-each select="/xsd:group/*[starts-with(@name,
$elementName)]/child[1]/child">
              <xsl:attribute name="minOccurs">0</xsl:attribute>
              <xsl:attribute name="maxOccurs">1</xsl:attribute>
              <xsl:copy-of select="."/>
            </xsl:for-each>
          </xsl:when>

          <xsl:when test="/xsd:group[ends-with(@name, '.children')]">
            <!-- Skip over this group, it is used by the match above -->
          </xsl:when>

          <xsl:when test="/xsd:complexType[1] and child[1]::xsd:sequence

and child[1]/child[1]::xsd:choice and child[1]/child[1]/(minOccurs='0')
and child[1]/child[1]/(maxOccurs='unbounded')">
              <!-- Iterate thru all elements adding min=0 and max=1 -->
              <xsl:for-each select="./child[1]/child[1]">
                  <xsl:attribute name="minOccurs">0</xsl:attribute>
                  <xsl:attribute
name="maxOccurs">unbounded</xsl:attribute>
                  <xsl:copy-of select="./child[1]/child[1]"/>
              </xsl:for-each>
          </xsl:when>

          <xsl:otherwise>
            <!-- We emit this element unharmed -->
            <xsl:value-of select="." />
          </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

what I want to do is
1. Remove any       <xsd:choice minOccurs="0" maxOccurs="unbounded">
and alter each of the elements that are children of this element to
include minOccurs="0" maxOccurs="1"
2. Remove any  <xsd:group that is referred to by a <xsd:group ...  with
a ref with a name ending with '.children' and pull in all the elements
in that group in line where the original reference occured.
3. Emit everything else unharmed.

Here is an abbreviated content of the file I am trying to transform with

examples of the contracts I am trying to alter.

The error I get when opening in Firefox is "
XML Parsing Error: junk after document element
Location:
file:///D:/DevProjects/mddlQuestFor/schemas/3.0-beta/mddl-3.0-test.xml
Line Number 7953, Column 14:</xsd:schema>g"

Which suggests to me I have not understood the output
-------------^

I also tried this

D:\DevProjects\mddlQuestFor\>java -cp
./xalan.jar;./xercesImpl.jar;./serializer.jar;./xmi-apis.jar
org.apache.xalan.xslt.Process -I
l -XSL normalised.xslt -OUT test.xml

Xalan: was not successful.

So maybe my syntax is wrong, but I cannot see where.

Thx.
