Using XERCES with XPath support

[Reuven Nisser]

Hello, I have an application relying heavily on XML. I am currently using MS-XML4. The application imports, builds, changes and exports XML documents and uses XPATH to find notes. The main reason for switching to XERCES is using Apache XML Security later. I am trying to migrate the application, I started with XERCES and then found out it has no XPATH support. I continued with XALAN but it does not allow to change the XML and if I use a wrapper I will need to rebuild it after each XML change. Do, where do I go from here? Is it possible to use Apache XML Security with other XML libraries? Especially with MS-XML 4? Thanks, Reuven Nisser
