Re: [xml-dev] Understanding the scope of XML catalog

["Imsieke, Gerrit, le-tex" <gerrit.imsieke@le-tex.de>]

Hi Ken,

You might also want to try this pure XSLT solution (using Saxon EE and 
the same catalog):

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:xs="http://www.w3.org/2001/XMLSchema";
  xmlns:saxon="http://saxon.sf.net/";
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  exclude-result-prefixes="xs saxon"
  version="3.0">

  <xsl:template match="/*">
    <xsl:variable name="schema" as="document-node(element(xs:schema))"
      select="doc(namespace-uri())"/>
    <xsl:variable name="with-schemaLocation"
      as="document-node(element(*))">
      <xsl:document>
        <xsl:copy>
          <xsl:copy-of select="@*"/>
          <xsl:attribute name="xsi:schemaLocation" 
select="namespace-uri(), base-uri($schema)"/>
          <xsl:copy-of select="node()"/>
        </xsl:copy>
      </xsl:document>
    </xsl:variable>
    <xsl:message
      select="serialize(
                saxon:validate($with-schemaLocation),
                map{'method': 'adaptive'}
              )"/>
  </xsl:template>

</xsl:stylesheet>

It loads the schema using the namespace URI of the top-level element 
(and the catalog mapping to the local file: URI). Then it attaches an 
xsi:schemaLocation attribute that consists of the namespace URI and the 
base URI of the local schema document.

$ saxon-EE-9.9.1.1 -xsl:ublval.xsl -s:invoice.xml
map{"valid":false(),"errors":map{"clause":"2.4","path":"/Q{urn:oasis:names:specification:ubl:schema:xsd:Invoice-2}Invoice[1]","colummn":37,"systemId":"","code":Q{http://www.w3.org/2005/xqt-errors}FORG0001,"line":14,"constraint":"cvc-complex-type","message":"In 
content of element &lt;Invoice&gt;: The content is incomplete. The 
following elements would be valid here, all in namespace 
urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2: 
PaymentExchangeRate, TaxExchangeRate, TaxTotal, 
PaymentAlternativeExchangeRate, LegalMonetaryTotal, WithholdingTaxTotal, 
AllowanceCharge, PaymentTerms, PrepaidPayment, PricingExchangeRate. 
","specPart":1}}
