I'm trying to use the msxsl.exe utility to do a simple differencing between two xml files that will generate another xml file that contains the differences between the two original xml files. I know there has to be some code out there that will get me pointed in the right direction. I have this copy code... I figure it can be modified to work with a little guidance. Any help would be appreciated... still learning.

Thanks!

<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>

Differencing between XML documents is a pretty complex subject, in defining exactly what differences you regard as significant, in deciding how they should be reported, and in devising and implementing algorithms. I'm afraid it's too big a problem for a simple answer.

I didn't think it was going to be tough... I'm pulling an identical data file, just at different times during the week. Some additions but mostly changes are made to the data within the xml, so I thought it wouldn't be that tough to compare each subsequent data file to the original and build a new xml data file (based on that same schema) out of the differences between each comparison. Not much changes each time and there are 24 data tags to parse in each record.

Good, let us know the answer when you've done it.

The problem is of course easier if you make the scope narrower, for example if you know the two files conform to the same schema and you are only looking for differences in data content, or if you have ID attributes that you can use as comparison anchors.

Take a look at Altovas Diff Dog. Maybe it can help.

Until I can get my xsl command line routine to run... I found some shareware out there that does difference comparison and output. If anyone's interested it's call ExamXML and you can get it here... http://www.download.com/ExamXML/3000...-10566218.html
