RE: [xsl] xpath expression in <xsl:stylesheet> element

["Sullivan, Dan" <dsullivan@xxxxxxxxxxx>]

If you are willing to keep all you favorite namespaces and schema
location in a configuration file, for example

mySchemas.xml file

<schemas>
  <schema>
    <namespace>urn:sample:A</namespace>
    <uri>http://www.develop.com/a.xsd</uri>
  </schema>
  <schema>
    <namespace>urn:sample:B</namespace>
    <uri>http://www.develop.com/b.xsd</uri>
  </schema>
  <schema>
    <namespace>urn:sample:C</namespace>
    <uri>http://www.develop.com/c.xsd</uri>
  </schema>
</schemas>


The this transform will add the appropriate schemaLocation to an input
file (watch for line wraps).

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
                version="1.0">
  <!-- generic identity xform -->
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
  <!-- matches if document element is in a namespace, but there is no
schema locations -->
  <xsl:template match="/*[not(@schemaLocation) and
namespace-uri()!='']">
    <!-- lookup schema location from a configuration file -->
    <xsl:variable name="location"
select="document('mySchemas.xml')/*/schema[namespace=namespace-uri(curre
nt())]"/>
    <xsl:copy>
      <xsl:if test="$location">
        <!-- this schema is in our configuration file, so add schema
location -->
        <xsl:attribute name="schemaLocation"
namespace="http://www.w3.org/2001/XMLSchema-instance";>
          <xsl:value-of select="$location/namespace"/><xsl:text>
</xsl:text> <xsl:value-of select="$location/uri"/>
        </xsl:attribute>
      </xsl:if>
      <!-- build out rest of document -->
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

Subject: [xsl] xpath expression in <xsl:stylesheet> element


I am trying to create a generic stylesheet for a number of different
input.xml. Each input.xml has a different factType which in turn has its
own schema whose location and name I want to specify in the output. (For
Example ideally I want the output root element to be
<LoginHypothesis
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance";
xmlns:ia="http://www.orincon.com/ia"; xsi:schemaLocation=
"http://www.orincon.com/ia LoginHypothesis.xsd">)

I would also like to automatically get the name of the schema from the
incoming document as opposed to having it hard coded in the stylesheet.

1) How do I get the "xsi:schemaLocation="http://www.orincon.com/ia
LoginHypothesis.xsd" text to appear?
2) Can I use xpath in the <xsl:stylesheet> element to extract this
LoginHypothesis factType value from the input.xml?

I have tried xsi:schemaLocation="http://www.orincon.com/ia
{ia:unorderedFact/child::factType/text()}.xsd" with no joy.

Any suggestions on how I handle this gratefully received.

Thank you

Annie

This is what I have at the moment
input.xml
<ia:unorderedFact
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance";
xsi:schemaLocation="http://www.orincon.com/ia UnorderedFact.xsd"
xmlns:ia="http://www.orincon.com/ia";>
     <factType>LoginHypothesis</factType>
     <slot>
          <tag>userName</tag>
          <ia:userName>jpublic</ia:userName>
     </slot>
     <slot>
          <tag>hostName</tag>
          <ia:hostName>linux1</ia:hostName>
     </slot>
...
</ia:unorderedFact>

stylesheet.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="

<xsl:output method="xml" indent="yes"/>
  <xsl:template match="ia:unorderedFact">
    <xsl:element name="{child::factType/text()}">
      <xsl:text/>
      <xsl:for-each select="//slot">
        <xsl:choose>
           <xsl:when test="count(child::*)=2">
             <xsl:element name="{child::tag/text()}">
               <xsl:value-of select="./*[position()=2]"/>
             </xsl:element>
             <xsl:text/>
           </xsl:when>
           <xsl:when test="count(child::*)>2">
......
</xsl:stylesheet>

output.xml
<?xml version="1.0" encoding="UTF-8"?>
<LoginHypothesis
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance";
xmlns:ia="http://www.orincon.com/ia";>
<userName>jpublic</userName>
