Hi

Thank you for the response.

I). I tried to use some params to hold reference:

<xsl:template name="prodAndRel">
    <xsl:param name="prod1"/>
    <xsl:param name="prod2"/>
    <xsl:param name="rel1"/>
    <xsl:param name="rel2"/>
<xsl:choose>
 <xsl:when test="position()=1">  <!--First pro_rel element comes in-->
 <xsl:param name="prod1" select="./@name"/>
 <xsl:param name="rel1" select="./@end_rel"/>
 </xsl:when>
 <xsl:otherwise>
  <xsl:if test=./@name != $prod1> <!--if this is not ABC, then must be XYZ-->
  <xsl:param name="prod2" select="./@name"/>
   <xsl:param name="rel2" select="./@end_rel"/>

</xsl:if>
 <xsl:if test="./@name = $prod1 and ./@end_rel &gt; $rel1"><xsl:param name="rel1" select="./@end_rel"/></xsl:if><!--ABC repeats, update the max_rel-->
  <xsl:if test="./@name = $prod2 and ./@end_rel &gt; $rel2"><xsl:param name="rel2" select="./@end_rel"/></xsl:if>><!--XYZ repeats, update the max_rel-->
 </xsl:otherwise>
</xsl:choose>
<xsl:if test="$prod1 !='' and $prod2 !='' and $prod1 != $prod2">
 <xsl:if test="$rel1 &lt; 3.0 and $rel2 &lt; 3.0">
  <xsl:call-template name="removeAll"/>
 </xsl:if>
 <xsl:if test="$rel1 &gt; 3.0">
  <xsl:call-template name="oneProd">
   <xsl:with-param name="prod1" select="$prod1"/>
  </xsl:call-template>
 </xsl:if>
 <xsl:if test="$rel2 &gt; 3.0">
  <xsl:call-template name="oneProd">
   <xsl:with-param name="prod2"  select="$prod2"/>

   </xsl:call-template>
 </xsl:if>
</xsl:if>

</xsl:template>

But it still doesn't work, I don't know why.

2).Yes, I'm using Xerces. The problem is if I knew that ABC != XYZ and both bb and dd are less than 3.0, I already inside <tl1_message> element, How can I skip it.  Would you please explain more detail. Or how can I removing the element after I creat it.

Thanks

Guo

1) Depending on how the document is parsed or if you're simply passed a model you may need to store the attribute values for comparison or simply retrieve them from the existing model.

2) This depends on the library you're using to parse the document (are you using JAXP? Xerces?) and can be done by skipping the element during parse time or by removing the element from the model after the model has been created.

Subject	[Wtp-wst-dev] Question for XML parsing

Hi, 
  
I'm parsing an XML file, there is an element named <tl1_message>
inside this file, it looks like: 
  
<tl1_message>
   <tl1_message_type> 
        ..
       ..
       .. 
    </tl1_message_type>
   <prod_rel name="ABC" start_rel="aa" end_rel="bb"/>
   <prod_rel name="XYZ" start_rel="cc" end_rel="dd"/>
   <other elements.../>
</tl1_message> 
This is my requirements: 

1). if ABC = XYZ and either bb or dd greater than 6.0, then
<tl1_message>
   <tl1_message_type> 
        ..
       ..
       .. 
    </tl1_message_type>
   <prod_rel name="ABC"/>
   <other elements.../>
</tl1_message> 
  
2). if ABC != XYZ and both bb and dd are less than 3.0, then
the entire element <tl1_message> should be removed.
My difficulty is:
1). How to compare bb and dd, they are in different element(in the same
level).
2). How to delete the entire element in this case.
  
Thanks
