Try to pattern match a field

I want to do the following in JScript:

var node = xmlData.selectNodes("//Row[@fld1(0)");

Where the XML is listed as the following:

<root>
   <Row fld1="1" fld2="Description1" fld3="5" />
   <Row fld1="1" fld2="Description1" fld3="10" />
   <Row fld1="2" fld2="Description2" fld3="5" />
   <Row fld1="2" fld2="Description2" fld3="11" />
   <Row fld1="3" fld2="Description3" fld3="15" />
   <Row fld1="3" fld2="Description3" fld3="13" />
</root>

I want it to return only the first occurance of every unique fld1 value.

AKA this:
<root>
   <Row fld1="1" fld2="Description1" fld3="5" />
   <Row fld1="2" fld2="Description2" fld3="5" />
   <Row fld1="3" fld2="Description3" fld3="15" />
</root>

I don't care about fld3 under a certain condition, but in other conditions I do.

Thanks..

Peter
