Re: [eXist-TEIXML] passing arguments to XQuery functions

Hi, The double slash seems to make no difference I'm afraid. I've used the eXist sandbox to verify the function works if I point it directly at one of my TEI files. The result in the webpage is that I see the separator ' - ' but no values for date of birth or death, which also suggests that $doc doesn't make it to the function. Also, the functions you see that add CSS and header text work fine - I assume because they don't contain expressions or pass an argument from the main query. Any help you could offer would be great! Here is the main query: http://snipt.org/ufiS3 Here is the function in question: http://snipt.org/ufiQ1 Regards, Chris On 13/03/12 11:16 PM, Peter Stadler wrote: > Maybe you're passing a document-node() to your module? > Can you try with a double slash after your $doc, e.g. $doc//tei:teiHeader/tei:profileDesc/tei:particDesc/tei:person/tei:birth/text() > and/or make it explicit via > declare function bibl:dob($doc as document-node()) as element() {...} > > Anyhow, I think we would need to see the whole files to be able to say more ... > > All the best > Peter > > Am 13.03.2012 um 10:58 schrieb Christopher Thomson: > >> Hi Martin, >> >> I'm not using<listPerson> as I believe<person> can be used directly in >> <particDesc>.
