I want xml like below,is there any way

 '<Grading_Automated><PassOrFail>Pass</PassOrFail><ActivityScorebased><AutomatedSequence Value="0"/><Percentage>40</Percentage><Value>34</Value><AutomatedSequence Value="1"/><Percentage>99</Percentage><Value>432</Value><AutomatedSequence Value="2"/><Percentage>43</Percentage><Value>232</Value><AutomatedSequence Value="3"/><Percentage>43</Percentage><Value>323</Value><AutomatedSequence Value="4"/><Percentage>33</Percentage><Value>432</Value><AutomatedSequence Value="5"/><Percentage>45</Percentage><Value>3432</Value></ActivityScorebased></Grading_Automated> 
If you want all '<PassOrFile>Fail' changed to '<PassOrFail>Pass' you have straight forward replace, perhaps with a regexp if <PassOrFail> is elsewhere in xml record.  If  you need to set specific values for specific records, your looking at parsing the xml (SAX, DOM, take you pick) and re-writing the record.
