Optimised for XML containing structured data, as opposed to XML documents which contain more narrative free-flowing content, XML Data Compare is the new comparison product from DeltaXML. XSLT filters are not necessary to tweak results. Adjust how the comparison is made and how the output is presented just using a config file. Before continuing, go grab your evaluation trial.
Once you have your evaluation copy you are ready to go!
Set up your REST server (see the REST user guide) and compare two of your data files using an empty config file.
The config file may require some thought about namespaces and what you need to adjust and there are several samples to help you on your way. You can always start with an ’empty’ config file and add to that if necessary. There’s more information on this page: Basics – Configuration File and a full definition in the Configuration File Schema Guide.
The samples are on Bitbucket; the whole project is here.
Postman provides access to the REST API or you can use the command line JAVA sample to run the comparison. Whatever way you choose it is simple to modify the config file and review the result file to see the changes that are produced. And you can develop your solution in whatever language you prefer.
To specify the nodes that are to be treated differently, the config file uses XPath expressions. I use an XML editor such as oXygen to check that I am using the right XPath expression. In oXygen, there is an XPath/XQuery builder window that can be used for this.
