Hi Monks,

The code shown in Re: Removing duplicate subtrees from XML works very well with the data shown in this posting. But with my data (as below) 

  

<species name = "hs">
 <sequence id = "1" title = "chromosome 1">
  <genome_feature type = "CDS">
   <gene id = "01">
    <gene_seq number = "1"></gene_seq>
   </gene>
  </genome_feature>
 </sequence>
</species>

<species name = "hs">
 <sequence id = "1" title = "chromosome 1">
  <genome_feature type = "CDS">
   <gene id = "17">
    <gene_seq number = "2"></gene_seq>
   </gene>
  </genome_feature>
 </sequence>
</species>

I get the following error messages:

Alterations that I made to the provided script were the addition of a few ErrorContext => 1 statements. And I have tested these slight alterations with the data used in the top posting link.
