For my purposes, i am limited to only using Xalan, which is a XSlT 1.0 processor. My question is there a way of numbering a specific element ,say <a>, that is a child of a given node, <b> and give it its own number.

So this could be a possible input:
<b>
  <a>
  <a>
  <a>
  <c>
  <d>
  <a>
  <a>
  <c>
  <a>
</b>


And this would be my desired output:
<b>
  <x num="1">
  <x num="2">
  <x num="3">
  <x num="4">
  <x num="5">
  <x num="6">
</b>

Thanks in advance to anyone that can help out!!

<xsl:template match="a">
  <x><xsl:number/></x>
</xsl:template>

Sorry,

 <xsl:template match="a">
  <x>
    <xsl:attribute name="num"><xsl:number/></xsl:attribute>
  </x>
</xsl:template>
