I have been thinking about different options to provide xml normalization meaning I want to be able to maintain xml files or unique nodes with information that is reused within a specific xml file. I gave it a try using xinclude but the parsers I have seen do not implement xpointer() scheme but only the element() scheme. On the other hand they do not provide way of selecting fragments using xpath expressions as XInclude propose thru #xpointer... included in the href attribute. Using element() I am able to maintain individual files and include just the particular nodes I need in my final xml files, however I have to keep the order of them because element works based on the position of children like element(/1/2) to say use the second child from root.
I was thinking about to use in the meanwhile (seems like xerces will support the xpointer scheme and even an xpath scheme someday as well as jaxen as I read from some dom4j postings) xslt to given the specific nodes with ids just build the resulting xml file where the nodes are repeated and I can make my xpaths simpler.
In both cases above I heve always the worry about the maintanance of those several files that host unique nodes and I am wondering if there is a better solution.
Still I think a better way has to exist and maybe this is using schemas. I hope some of you could give me directions about where to look for a good solution.
Thanks in advance Nestor
