check nodes for a previous value

[tburrows]

I have an xml file with the structure
<datatable>
<jmmain_nmmain_archrg>
<last>
<first>
<id>
<charge>
so on
</jmmain_nmmain_archrg>

I am outputting the info into a table on a website. The problem is that if a person has more than one charge, then all the name info, id, etc. is repeated. What I would like to do is that when I get to a new name that all the duplicate name info from the next records would not be picked up and only the charge info from each record picked up for the table.
