Hello Pete,

I make this:
It is working, but I think, maybe is not optimize.
Do you know a better way?

I use this file. I read it and change the values.

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <header eventId="Rt-Test Old eventId 000001111" version="Rt-Test Old
version V2.01" timeStamp="Rt-Test Old timeStamp 22.02.2008">
        <location lineNo="Rt-Test Old lineNo Line0931" statNo="Rt-Test Old
statNo 920-270" statIdx="Rt-Test Old statIdx 534523" />
    </header>
    <event>
        <partProcessed identifier="Rt-Test Old identifier 4545353535353"/>
    </event>
    <body>
        <identifierType>FL</identifierType>
        <resHead result="Rt-Test Old result 3333" typeNo="Rt-Test Old typeNo
3333" />
        <partCount>Rt-Test001 partCount Neu</partCount>
        <results>
            <result position="1" state="Rt-Test Old state 3333" removed="Rt-
Test false"/>
        </results>
        <items>
            <item name="Component1.timeStamp" value="Rt-Test001 timeStamp"
dataType="8"/>
            <item name="Component1.Identifier" value="Rt-Test002 Identifier"
dataType="8"/>
        </items>
    </body>
</root>

Regards Andreas
