Sorry, I hit Send too quickly. With input like this: <rss ...some attributes> <channel ...some attributes> <title>value may be mixed</title> <link>value</link> ...more siblings that do not repeate <item> <title>value</title> <description> mixed content</description> <link>value</link> ...more descendants </item> <item> ...</item> ...more items </channel> </rss> I would like XML output like this: <root> <row> <rss-attr1>value</rss-attr1> ...more rss/@* as elements <channel-attr*>value</channel-attr*> ...more channel/@* <channel-title>value or perhaps CDATA surrounding mixed content</channel-title> <channel-link>value</channel-link> ... all other non-repeating siblings in order as elements <item-title>value for first item</item-title> <item-description> probably CDATA around mixed content</item-description> ...all other item fields in order traversing depth-first </row> <row>...again rss attributes, channel attributes, non-repeating children of channel followed by fields for second item </row> ...more rows ... </root> This example is for a single level of repeating descendants, but my solution has to be able to handle any level of repeating descendants. More over, the stylesheet has no knowledge of the structure of the input document. I have a solution that works ok by traversing the input document in doc order -- but it does not handle the siblings of repeating nodes that are not themselves repeating. I have thought of doing this the opposite way, get a key of all repeating nodes and process only those at the lowest depth to generate rows. I haven't actually written the logic. Any better ideas would be welcome. --- On Thu, 12/3/09, Michael Kay <mike@xxxxxxxxxxxx> wrote: > From: Michael Kay <mike@xxxxxxxxxxxx> > Subject: RE: Generic stylesheet to flatten XML hierarchy > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Date: Thursday, December 3, 2009, 3:54 PM > > I've been wandering through the > archives and other searches > > and so far have not found exactly what I am hoping to > find.
