Re: XPath Against OpenXML and OpenOffice Spreadsheets?
Ronnie The .RELs bit is how OOXML maintains references between different XML documents and other file-types in the single compressed ZIP package file. For example each XML worksheet will be saved as a separate document, but .RELS allows links between the two worksheets to be followed. There's an open source tool called Open XML Package Explorer that is .RELS aware that may help if you need to traverse related documents. Commercial XML Suites now have this capability too. If you're just looking at a single ODF or OOXML worksheet however, then a simple ZIP-Package compatible XPath tool like SketchPath may help to generate the possibly lengthy XPath expressions you will need. Also, it would be useful if XSLT 2.0 processor implementations supported fn:document() functions containing URLs starting with zip:/// but I'm not sure which ones do.
