Thank you for the extensive xquery support. The query functionallity is really impressive. The tool is extremly performant. Now I have come over an xliff file that contains namespaces. At file import into the db I activated the internal parser, parsing of entities and DTDs, chopping of whitespaces, text index, attribute index, path summary and all full text options except TF/IDF scoring and Stopword list. > > The root element looks like: > <xliff xmlns="urn:oasis:names:tc:xliff:document:1.2" xmlns:anotherNamespace="http://www.anotherNameSpace.com/some/element" version="1.2"> > > I can perform a full text search on all attributes such as //@id or count(//@id) returning over 6000 hits. > Performing a query for an element i.e. //note/ does not find any hits although there are note elements containing text in the file. > > Do you have any suggestions? > > > Thanks again for you help. > > Regards, > Jörg > > > > ________________________________ > > Jörg Beisiegel > Geschäftsführer / Managing Director > Localization Consulting > Desk phone: +49 7275 98933-22 > mailto:joerg.beisiegel at translatissimo.de > translatissimo Übersetzung und Lokalisierung GbR > Bismarckstr. 19 * D-76870 Kandel * Germany > http://www.translatissimo.de > > *** HINWEIS *** NOTE *** > Falls die Mail Anhänge enthält, bitte Empfang bestätigen. > If this mail contains attachments please confirm receipt. > > -----Ursprüngliche Nachricht----- > Von: Andreas Weiler [mailto:andreas.weiler at uni-konstanz.de] > Gesendet: Montag, 30.

The namespace without prefix, e.g. > xmlns="urn:oasis:names:tc:xliff:document:1.2" is the default namespace of all the elements below it. As the <node/>-elements thus have a non-empty namespace, they aren't found by the query //node (implying am empty NS). There are two solutions: 1. As this is the default element namespace, you could simply declare it in your query: > declare default element namespace > "urn:oasis:names:tc:xliff:document:1.2"; > //note 2. Generally you can also bind it to a prefix and use that in your query: > declare namespace xliff = "urn:oasis:names:tc:xliff:document:1.2"; > //xliff:note I hope this helps, Cheers Leo
