XSL code not have the desired OUTPUT

[perlnoob]

Hi every one, I have a question for xslt and xml output
I need to extract the text from creator or p with attribute class tags but if the creator and p with attribute class tags are the same I will not output the p tags. and each enclosed it with element name <bydesc>

XML input

<Article>
  <metadata>
    <creator>William Smith</creator>
    <creator>John Smith</creator>
 </metadata>
 <content
   <main>
   <p class="author">William Smith, John Smith</p>
   <p class="author">Jonathan Smith</p>
   </main>
</content>
<Article

>

XSL

<xsl:template name="BYLINE">
    <xsl:variable name="vByline">
       <xsl:apply-templates select="/Article/metadata/creator | /Article/content/main/p[@class='author' and not(text() = /
/dc_creator/text())]" mode="byline"/>
    </xsl:variable>
      <xsl:if test="string-length(normalize-space($vByline))!=0">
      <xsl:element name="BYLINE">
        <xsl:element name="bydesc">
        <xsl:value-of select="$vByline"/>
      </xsl:element>
      </xsl:element>
    </xsl:if>
  </xsl:template>

the produced OUTPUT

<BYLINE><bydesc>William SmithJohn SmithJonathan Smith</bydesc></BYLINE>

the OUTPUT should be

<BYLINE>
       <bydesc>William Smith</bydesc>
       <bydesc>John Smith</bydesc>
       <bydesc>Jonathan Smith</bydesc>
</BYLINE>

Again thank you for the bighelp.....thank you
