particular tag name h as non-empty String value


Hi All,

I run into a problem where I'm not able to check  whether any 
of child node with particular tag name has empty String value.  

Here's the XML:

      <ATTACHMENT>
              <ATTACHMENT_NAME></ATTACHMENT_NAME>
              <ATTACHMENT_LINK> http://yahoo.com </ATTACHMENT_LINK>
              <ATTACHMENT_NAME> link </ATTACHMENT_NAME>
              <ATTACHMENT_LINK> http://msn.com </ATTACHMENT_LINK>
      </ATTACHMENT>

The requirement is to do something ANY of the 
<ATTACHMENT_NAME> elemement has non-empty String.  Here's the 
XSL I wrote:

      <xsl:template match="ATTACHMENT">
              <xsl:if 
test="string(normalize-space(child::ATTACHMENT_NAME))">
                      <P>
                              <B>ATTACHMENT:</B>
                              <xsl:for-each select="ATTACHMENT_NAME">
                                      <xsl:variable 
name="href" select="following-sibling::ATTACHMENT_LINK" />
                                      <a href ="{$href}">
                                              <xsl:apply-templates />
                                      </a>
                                      <br/>
                              </xsl:for-each>
                      </P>
              </xsl:if>
      </xsl:template>

But from the result I got, seems like the decision is only 
based on the first <ATTACHMENT_NAME> element it found, and 
totally ignore the later ones. i.e. if the first 
<ATTACHMENT_NAME> has empty String value but the second one 
has String value "link" in it, it won't fall into the if block. 

Thanks in advance for any suggestions!
