Getting the document path in a collection using XQuery
Say I have a collection c with xml documents x.xml, y.xml, and z.xml and that I've added them using "to" so that they are found here: collection('c/x') ... Let's say that in each document I have a node <code/>, so in x.xml I have <code id='1'/>, in y.xml I have <code id='2'/>, etc. I can query across the documents to find the <code/> node with id = 2 pretty easily. But now that I've found it, I want to do further queries limiting myself to that document. In other words, I want to learn using XQuery that the <code/> node with id = 2 is in collection('c/y'). How can I do this? TIA, Chas.
Hi Chas, you could use the function fn:document-uri(): http://www.w3.org/TR/xpath- functions/#func-document-uri . A working example which I tested with BaseX is //code[@id = '2']/root()/document-uri() Cheers, Dimitar Am Montag 30 Mai 2011, 03:03:19 schrieb chas@munat.com:
