Hi,
i try to generate from a gml-file (geography markup language) an
svg-file using java (xalan) (i'm using java 1.4.2)

My problem is now dealing with namespaces in xslt (at least this is
what i guess).

the gml-file looks like this:

<?xml version='1.0' encoding='UTF-8'?>
<ogr:FeatureCollection xmlns:gml='http://www.opengis.net/gml'
xmlns:xsi='http://www.w3c.org/2001/XMLSchema-instance'
xmlns:ogr='http://ogr.maptools.org/'
xmlns='http://gdal.velocet.ca/ogr'
xsi:schemaLocation='http://gdal.velocet.ca/ogr defol.xsd'>
  ...
  <gml:featureMember>
    <defol>
      <cat>1</cat>
      <area>2668790.35979</area>
      <perimeter>8356.95744649</perimeter>
      <sites_for_>2</sites_for_>
      <sites_for1>1</sites_for1>
      <site_id>10</site_id>
      <oid_>2</oid_>
      <objectid>59</objectid>
      <site_id_1>10</site_id_1>
      <ogr:geometryProperty>
           <gml:coordinates>796418.625,...


the xsl-file:
<?xml version="1.0" encoding="ISO-8859-1"?>
  <xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:gml="http://www.opengis.net/gml"
xmlns:ogr="http://gdal.velocet.ca/ogr"
xmlns:xs="http://www.w3.org/2001/XMLSchema">

   <!-- root template -->
   <xsl:template match="/">
      <svg width="400" height="400">
         <g>
           <xsl:apply-templates />
         </g>
      </svg>
    </xsl:template>
    ....
    
    
    <!-- toplevel template -->
    <xsl:template match="gml:featureMember">
      test1
      <xsl:apply-templates select="ogr:defol"/> 
    </xsl:template> 

    <!-- named templates -->
    <!-- namespaces, also the default ns, must be given explicitely
-->
    <xsl:template match="ogr:defol">
      test2
      <xsl:apply-templates select="ogr:geometryProperty"/> 
      <xsl:apply-templates select="ogr:site_id"/> 
      <xsl:apply-templates select="ogr:cat"/> 
    </xsl:template> 

    <xsl:template match="ogr:cat">
      cat = <xsl:value-of select="."/>
    </xsl:template>

    <xsl:template match="ogr:geometryProperty">
      test3
      <xsl:apply-templates select="gml:Polygon"/> 
    </xsl:template>
    ...

The result is:
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ogr="http://gdal.velocet.ca/ogr"
xmlns:gml="http://www.opengis.net/gml" height="400" width="400"><g>
  
  
      test1
      
      test2
      
      cat = 1
</g></svg>


the problem i have now is that the element ogr:geometryProperty is not
matched by the template. The problem seems to be the ogr-prefix (which
is the default namespace in the gml-file).

Any ideas? 
Thanx very much in advance
