[whitesox99]

Hi,

Have the following sample xml, xsl and the jave code. But getting the following error:

Compiler warnings:
  line 18: Illegal attribute 'expr'.
ERROR:  'Syntax error in ''.'
FATAL ERROR:  'Could not compile stylesheet'
javax.xml.transform.TransformerConfigurationException: Could not compile stylesheet
	at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.java:824)
	at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTransformer(TransformerFact

Here is the sample xml:

        <contents>

      </entity>
    </contents>
  </entity>
</tree>

And here is the XSL:

<?xml version="1.0"?> 
<xsl:stylesheet xmlns:xsl="[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform"[/URL] version="1.0">

<xsl:template match="tree">
  <xsl:apply-templates select="entity"/>
</xsl:template>

<xsl:template match="entity">
  <div onclick="window.event.cancelBubble = true;clickOnEntity(this);" onselectstart="return false" ondragstart="return false">
  <xsl:attribute name="image"><xsl:value-of select="image"/></xsl:attribute>
  <xsl:attribute name="imageOpen"><xsl:value-of select="imageOpen"/></xsl:attribute>
  <xsl:attribute name="open">false</xsl:attribute>
  <xsl:attribute name="id">f<xsl:value-of select="@id"/></xsl:attribute>
  <xsl:attribute name="open">false</xsl:attribute>
  <xsl:attribute name="STYLE">
    padding-left: 20px;
    cursor: hand;
    <xsl:if expr="depth(this) > 2">
      display: none;
    </xsl:if>
  </xsl:attribute>
    <table border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td valign="middle">
          <img border="0" id="image">
            <xsl:attribute name="SRC">
              <xsl:value-of select="image"/>
            </xsl:attribute>
          </img>
        </td>
        <td valign="middle" nowrap="true">
        <xsl:attribute name="STYLE">
          padding-left: 7px;
          font-family: Verdana;
          font-size: 11px;
          font-color: black;
        </xsl:attribute>
        <xsl:value-of select="description"/></td>
      </tr>
    </table>
  <xsl:apply-templates select="contents/entity"/>
  </div>
</xsl:template>

</xsl:stylesheet>

Here is the java code:

            XslTransform xslTransform = new XslTransform () ;
            TransformerFactory tFactory = TransformerFactory.newInstance () ;
            Transformer transformer = tFactory.newTransformer ( new StreamSource ( new File ( "C:\\tree.xsl" ) ) ) ;
            transformer.transform ( new StreamSource ( "C:\\tree.xml" ) , new StreamResult ( new FileOutputStream ( "C:\\treeout.txt" ) ) ) ;

The error is due to the following in xsl

<xsl:if expr="depth(this) > 2">
      display: none;
    </xsl:if>

Any idea on how to fix this error to get the right output. Any help is appreciated.

Thanks

I think there's a problem with the xsl, you should ask this in the XML forum.

Cheers,
