InfoPath Dev

I want to fill a repeating table with a data connection to a xml (included in the project as a resource file). This works fine in the Infopath preview but not in the browser (IE). The "Design Checker" doesn't warn me anytime.

The xml looks like this:

<?xml version="1.0" encoding="utf-8"?>
<ColumnNames>
  <option id="oa" selected="false" text="first choice"/>
  <option id="ob" selected="false" text="second choice"/>
</ColumnNames>

or this

<?xml version="1.0" encoding="utf-8"?>
<ColumnNames>
  <option>
    <id>oa></id>
    <selected>false</selected>
    <text>first choice</text>
  </option>
  <option>
    <id>ob></id>
    <selected>false</selected>
    <text>second choice</text>
  </option>
</ColumnNames>

and several combinations...


The attributes/elements "id" and "text" are text boxes and "selected" is a checkbox.

As already mentioned it works fine in the preview but why does the Form Services report this error:

Unexpected end of file while parsing Name has occurred. Line 1, position 5175.
