Note: I am using PipelinedComparator to compare the files. If you see the difference between the expected result and the got result, the result that i got is collapsed blacklining.

Here in the old xml I have a table with two rows with footnoteref element and in the new xml i have deleted the first row. I compared the two xmls. In the diff xml I have the result as the first row as modified and the second row as deleted.
What can I do to resolve this problem. I am helpless. Could you help me how to do?

Hi Arul,

Firstly, from the example output you have included, it looks like you are using an older version of DeltaXML Core. We have recently released version 5.0 which, among other things, includes a new improved result format. You can download this at http://www.deltaxml.com/library/downloads.html and request a new evaluation key to use with this version.

I have tried to reproduce the result that you are getting from this comparison and I am unable to. Firstly, I had to edit the XML documents you included above as they were not valid. The </sec> closing tags needed to be changed to </sect1> closing tags. Comparing these new valid inputs with various settings always gave me the result you were expecting, with the first row being deleted. Are you using any input filters on the documents before you compare them?

You are using the PipelinedComparator to compare your documents. One setting that you may not be aware of is the Enhanced Matcher. This improves the matching of elements by evaluating the PCDATA in their subtrees. In your example, the Enhanced Matcher would cause the row in the second input to match with the second row of the first input based on the PCDATA inside it. To ensure the Enhanced Matcher is on, use the following line in your code:

pc.setComparatorFeature("http://deltaxml.com/api/feature/enhancedMatch1", true)

assuming your PipelinedComparator instance is called 'pc'

To further improve the matching when using the Enhanced Matcher, word by word comparison can be used. This requires the addition of an input filter and some output filters to the pipeline. If you are using Core 5.0, add com.deltaxml.pipe.filters.dx2.wbw.WordInfillter as the last input filter and com.deltaxml.pipe.filters.dx2.wbw.WordSpaceFixup and com.deltaxml.pipe.filters.dx2.wbw.WordOutfilter as the first two output filters.
Take a look at http://www.deltaxml.com/free/examples/core-features/word-by-word for an explanation of word by word comparison.

Hopefully this should help you solve your problem. If you are using your own input filters, try the comparison without them first to see if they are the cause of the problem. Do ask further questions if you are still having problems getting the correct result.
