Querying Inner Text with Multiple Attributes

Please refer to the following node

<GKENTD.ACDSEGMENT accounted=”DR” index=”1″>2000</GKENTD.ACDSEGMENT>

I am stuck on how to query the inner text of ’2000′ into a variable, by filtering on the two attributes. There are more of these I have to query (index=2,index=3,etc.)

This is what I have been playing with, I know its wrong, but can / should I even be using Select-XML in this case?

$GLSegment1 = Select-XML -XML $PY -XPATH “//EXTCHARGEDISTRIBUTION//GKENTD.ACDSEGMENT[accounted='DR'][index='1']”

Any help would be most appreciated, this is the only thing I cannot get past for this one script I am doing…

Thank you
