how to specify namespace in saxon api ??

[Gabriel]

Greetings, After 6 hours of fruitless research, I ask for your help !

I have an svg file and use Saxon latest implementation, openSource version.

it holds nodes whose path are :
svg/g[@id='textes_x00 20_et_x0020_puc es']/g/text

each text node possess a transform attribute that I want to work with.

The problem is that whatever xPath expression I use, I never fetch any
nodes. According to the samples, it works with regular xml but doesn't
with svg (which is xml !). But well, it just doesn't :(
I tried to get svg width attributes as well but nope

After a lot of research it happenedn that sxon does not know about the
svg namespace. How can I tell him to be aware of it ??
Any ideas ?
The code :

import net.sf.saxon.xp ath.XPathEvalua tor;
import net.sf.saxon.xp ath.XPathExpres sion;
import net.sf.saxon.xp ath.StandaloneC ontext;
import net.sf.saxon.om .NodeInfo;
import net.sf.saxon.xp ath.Variable;
import org.xml.sax.Inp utSource;
import javax.xml.trans form.sax.SAXSou rce;

import java.util.List;
import java.util.Itera tor;

public void go(String filename) throws Exception {

// Create an XPathEvaluator and set the source document

InputSource is = new InputSource(fil ename);
SAXSource ss = new SAXSource(is);
XPathEvaluator xpe = new XPathEvaluator( ss);

StandaloneConte xt sc = (StandaloneCont ext) xpe.getStaticCo ntext();
String expression = "//LINE[contains(., $word)]";

Variable wordVar = sc.declareVaria ble("word", "");
// Set the value of the XPath variable
wordVar.setValu e("svg");
//expression = "//g[@id='textes_x00 20_et_x0020_puc es']/g/text";
// Compile the XPath expressions used by the application
XPathExpression findLine = xpe
.createExpressi on(expression);

// Find the lines containing the requested word
List matchedLines = findLine.evalua te();

// Process these lines
for (Iterator iter = matchedLines.it erator(); iter.hasNext(); ) {

// Get the next matching line
NodeInfo line = (NodeInfo) iter.next();

// // Find where it appears in the play
// findLocation.se tContextNode(li ne);
// System.out.prin tln("\n" +
findLocation.ev aluateSingle()) ;
//
// // Find out who the speaker of
this line is
// findSpeaker.set ContextNode(lin e);

// Output the name of the speaker and the content of the
// line
// System.out.prin tln(findSpeaker .evaluateSingle () + ": "
// + line.getStringV alue());
// Finish when the user enters "."

}
System.out.prin tln("Finished." );

}
