RE: [xsl] compare two unicode variables

[hochen@xxxxxxxxxxx]

Thanks for all your help. The problems are indeed related with Length. But it is
still puzzling. I tried the following code:

 <xsl:for-each select="Entry">
	     
<xsl:variable name="Wentry"><xsl:value-of select="ENTRY_FORM"/></xsl:variable>
      
 <xsl:variable name="Centry" select="substring($Wentry,1,1)"/>
 		
  <xsl:variable name="Kentry1" select="'&#x00E1;'"/>
         
           <xsl:if test="$Centry=$Kentry1">
          
       	    <option value="{position()+1}">
       	  
            <xsl:value-of select="$Wentry" />
            </option>   
   	   
	   </xsl:if>
            
  </xsl:for-each>

 I force the Kentry to be "&#x00E1;" and Entry_form to be Length 1. Then it
works. But when I put them here:
<xsl:for-each select="/reportname/Entry[substring(ENTRY_FORM,1,1) =
substring($Kentry,1,$wordLength)]">

It still doesn't work, so I don't know what happened. Even I gave value "xE1" to
Kentry, it still doesn't work.

Please help me again!

Thanks
Helen
