Fwd: xmlns ignore

[Michael Kay]

You clearly didn't understand David's answer.
 
You can no more "ignore" a namespace declaration in your source document
than you can ignore the first character of each element name. The namespace
is an intrinsic part of the names of your elements, and when selecting
elements by name, you need to be aware of it.
 
If you want to use unqualified names in your XQuery expression to refer to
names in a namespace, you can do this by means of a default namespace
declaration in the XQuery prolog: 
 
declare default element namespace " <http://www.portalfiscal.inf.br/nfe>
http://www.portalfiscal.inf.br/nfe"
 
However, you need to be aware that this affects the interpretation of all
unprefixed names in your query, not only those in a path expression.
 
If you don't want to change the source of the query, you can achieve the
same effect using the Saxon API:
 
comp.declareNamespace("", " <http://www.portalfiscal.inf.br/nfe>
http://www.portalfiscal.inf.br/nfe");
 
Your example query will then work as written. Note, however, that this is a
very different thing from "ignoring" the namespace.

Hi,  

This is a complete code test:

         
//--------------------------------------------------------------------------
------------------------------------------------------- 

          Processor proc = new Processor(false);
     
          
          XQueryCompiler comp = proc.newXQueryCompiler();
     
          XdmNode source = proc.newDocumentBuilder().build(new
StreamSource(inputFile));
     
     
          

          XQueryExecutable exp = comp.compile("/NFe/infNFe/ide/natOp"); 

          XQueryEvaluator eval = exp.load();
          eval.setContextItem(source);        
         
         
          

          XdmItem i =eval.evaluateSingle();
          System.out.println(i.getStringValue()); 

          
          
          XdmValue v = eval.evaluate(); 
          System.out.println(v.size());


//--------------------------------------------------------------------------
-------------------------------------------------------

that is the xml file:


//--------------------------------------------------------------------------
-------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<NFe xmlns="http://www.portalfiscal.inf.br/nfe">
        <infNFe Id="NFe2907" versao="1.10">
            <ide>
                <cUF>29</cUF>
                <cNF>123658</cNF>
                <natOp>Venda - direta</natOp>
....

//--------------------------------------------------------------------------
-------------------------------------------------------

The ""http://www.portalfiscal.inf.br/nfe"" return page not found. If I
remove the addres, the program return the correct value. That is way a fink
to ignore the addres. Is that possible?

A namespace declaration is not an attribute in the XDM model used by
XPath and Xquery. The name of an element includes the namespace.

Most likely the part of teh code that you don't show

= comp.compile("/.../... ...");

is selecting elements in no-namespace, and you should change it to
select elements in the namespace used in your xml source.

either by using a prefix
/p:aa/p:bb

and binding p to the namespace used in the source, or by setting the
default namespace in the xquery to that used in the source.
