RE: [xsl] Outputing Differences between two files

["Michael Kay" <mike@xxxxxxxxxxxx>]

For all problems involving looking for duplicates, or grouping, use
Muenchian grouping in XSLT 1.0 or xsl:for-each-group in 2.0.

It's a little hard from this problem description to see how it would
extrapolate to different input files. For example, what output would you
want if the input were:

> <a>
>    <b>Value1</b>
>    <bb>Value2</bb>
>    <bbb>Value3</bbb>
> </a>
> <c>
>    <b>Value1</b>
>    <bb>Value4</bb>
>    <bbb>Value5</bbb>
> </c>

or if it were:

> <c>
>    <b>Value4</b>
>    <bb>Value2</bb>
>    <bbb>Value5</bbb>
> </c> 
> <a>
>    <b>Value1</b>
>    <bb>Value2</bb>
>    <bbb>Value3</bbb>
> </a>
