Are you saying your xml file looks like:
<Pages>
<PageSize></PageSize>
<Info></Info>
<Page> (1st page) data for one form</Page>
<Page> (2nd page) data for second form</Page>
</Pages>
you may need to look at the data format in Planet Press to see how you are viewing the xml. We found that when we put all of the data for one form inside the second element tags (as in the Page tag above) below the root, we had to change the xml emulation to look at the "second elemnet". Otherwise the xPath and Planet press seemed to loose its place.
