I am trying to run a query over some XML data using XQuery, Saxon and Java.
And I would like to read the XML data from a string, not a file. I haven't figure out which classes to use, as many classes implement the Item interface. I tried a few with no luck.. maybe I am not on the right track. Please let me know what is the right way.
String stringSource = "xml input data";
final Configuration config = new Configuration();
final StaticQueryContext sqc = config.newStaticQueryContext();
final XQueryExpression exp = sqc.compileQuery(new FileReader("xquery.file"));
final DynamicQueryContext dynamicContext = new DynamicQueryContext(config);
dynamicContext.setContextItem(new StringValue("stringSource")); //?????????????????? line that needs to be modified
final Properties props = new Properties();
//... set propos
exp.run(dynamicContext, new StreamResult(new File("output.file")), props);
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
You seem to have found a forum that was dormant, but has re-appeared from a long sleep as a result of SourceForge migrating to the new platform. I would recommend using the forums at saxonica.plan.io in preference.
You are using Saxon's original Query API which is rather messy and "for internal use". For external use I would recommend use of the interfaces in the s9api package.
What you are doing should work fine, except that you are not setting the SystemID of the Source object; this means that Saxon doesn't know its base URI, which means any attempt to resolve relative URIs from this document will fail.
