Category: None Group: None Status: Open Priority: 5 Private: No Submitted By: Michael (mthenderson) Assigned to: Nobody/Anonymous (nobody) Summary: xpath fails to return results Initial Comment: I am having a issue using xpath. We are receiving a file from an external vender. When we use xpath to parse the file, we don’t get any results. Below is a brief example. <?xml version="1.0" encoding="UTF-8"?> <TXLife Version="2.16.01" xmlns="http://ACORD.org/Standards/Life/2"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://ACORD.org/Standards/Life/2 TXLife2.16.01.xsd"> <TXLifeRequest> <TransRefGUID>abc1234567</TransRefGUID> </TXLifeRequest> </TXLife> The following code returns no result List nodes = doc.selectNodes("//TransRefGUID"); I realize it's due to the default namespace declaration, but the file comes from an external vendor and we have not control over it. Is there a fix for this? Is there a work around? We have no control over the incoming xml.

The prefix in the query has no bearing in the actual query so the following demo show how to do this -------------- import java.io.StringReader; import java.util.Collections; import java.util.List; import org.dom4j.Document; import org.dom4j.XPath; import org.dom4j.io.SAXReader; import org.dom4j.xpath.DefaultXPath; public class xp { public static void main(String[] args) throws Exception { String xml = "" + "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" + "<TXLife Version=\"2.16.01\" xmlns=\"http://ACORD.org/Standards/Life/2\"; xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"; xsi:schemaLocation=\"http://ACORD.org/Standards/Life/2 TXLife2.16.01.xsd\">" + " <TXLifeRequest>" + " <TransRefGUID>abc1234567</TransRefGUID>" + " </TXLifeRequest>" + "</TXLife>"; Document doc = new SAXReader().read(new StringReader(xml)); XPath xpath = new DefaultXPath("//x:TransRefGUID"); xpath.setNamespaceURIs(Collections.singletonMap("x", "http://ACORD.org/Standards/Life/2";)); List nodes = xpath.selectNodes(doc); System.out.println(nodes); } } ------- this produces the following output [EMAIL PROTECTED] [Element: <TransRefGUID uri: http://ACORD.org/Standards/Life/2 attributes: []/>]] Mike Skells ---------------------------------------------------------------------- Comment By: Michael (mthenderson) Date: 2007-08-07 20:03 Message: Logged In: YES user_id=1862440 Originator: YES Thanks, that did the trick. Mike ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2007-08-07 15:10 Message: Logged In: NO Use DocumentFactory for creating document and set it's namespace map for XPath: namespaces.put("default", "http://ACORD.org/Standards/Life/2";); DocumentFactory documentFactory = DocumentFactory.getInstance(); documentFactory.setXPathNamespaceURIs(namespaces); reader = new SAXReader(documentFactory); Than you can use "default" as prefix for your namespace: List nodes = doc.selectNodes("//default:TransRefGUID"); You can try empty prefix: namespaces.put("", "http://ACORD.org/Standards/Life/2";); but I can't remember if this works. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=216035&aid=1769459&group_id=16035 ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
