Deleting text node causes some XPath select queries to fail
-----------------------------------------------------------
Key: XMLBEANS-331
URL: https://issues.apache.org/jira/browse/XMLBEANS-331
Project: XMLBeans
Issue Type: Bug
Components: XPath
Affects Versions: Version 2.1, Version 2.2
Environment: Windows XP Service Pack 2, JDK 1.6.0_01
Reporter: Steffan Westcott
Deleting TEXT tokens in a document appears to confuse the selectPath()
functionality. Here is a complete demonstration program :
package bug;
import org.apache.xmlbeans.XmlCursor;
import org.apache.xmlbeans.XmlObject;
public class Bug {
static String doc ="<?xml version='1.0'
encoding='UTF-8'?><a><b/>text<b/></a>";
static String query = "//b[2]";
public static void main(String[] args) {
try {
// Initialise XmlObject and cursor
XmlObject obj = XmlObject.Factory.parse(doc);
System.out.println("Intitial document :\n" + obj.toString());
XmlCursor cur = obj.newCursor();
// Select the second b node - Works fine...
cur.selectPath(query);
System.out.println(query + " finds " + cur.getSelectionCount() + "
objects");
// Delete the text node
cur.toStartDoc();
cur.selectPath("/a/text()");
cur.toSelection(0);
cur.removeXml();
System.out.println("After removing text node :\n" + obj.toString());
// Select the second b node - Doesn't work!!!
cur.selectPath(query);
System.out.println(query + " finds " + cur.getSelectionCount() + "
objects");
cur.dispose();
} catch (Exception e) {
e.printStackTrace();
}
}
}
This produces the following output :
Intitial document :
<a>
<b/>
text
<b/>
</a>
//b[2] finds 1 objects
After removing text node :
<a>
<b/>
<b/>
</a>
//b[2] finds 0 objects
