Question

I want to compare two xml raw files and capture their differences in data. For example,

    <Segment>
      <SegNum>2</SegNum>
      <Dt>20110910</Dt>
      <Comment>B test</Comment>
    </Segment>
  </Retrieve>
</info>

File B:

<info>
  <Retrieve>
    <LastNameInfo>
      <LNameNum>2</LNameNum>
      <NameType/>
      <LName>TESTING</LName>
    </LastNameInfo>
    <Segment>
      <SegNum>1</SegNum>
      <Status>HS</Status>
      <Comment>A test</Comment>
    </Segment>
    <Segment>
      <SegNum>2</SegNum>
      <Dt>20110</Dt>
      <Comment>COULD I USE LINQ</Comment>
    </Segment>
  </Retrieve>
</info>

so the output i need should be a file with just the differences like

              <LNameNum>1</LnameNum> File 2:<Lnamenum>2</Lnamenum>

Answer 1

There is a library (and tool), XML Diff and Patch, published to MSDN a while back that does this.
