DTMNodeProxy.getTextContent() does not return text content of child nodes
-------------------------------------------------------------------------
Key: XALANJ-2473
URL: https://issues.apache.org/jira/browse/XALANJ-2473
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Components: DTM
Affects Versions: 2.7.1
Environment: Java 1.5
Reporter: Christian Schröder
If a java extension functions takes an org.w3c.dom.Node as an argument then it
gets an org.apache.xml.dtm.ref.DTMNodeProxy object.
The "getTextContent" method of this object returns null if the node is an
element node, although according to the java 1.5 documentation, the
"getTextContent" method should return the "concatenation of the textContent
attribute value of every child node".
This is the implementation:
public String getTextContent() throws DOMException {
return getNodeValue(); // overriden in some subclasses
}
Of course, "getNodeValue" returns null for the "foo" node, but I think this is
not the way "getTextContent" should be implemented.
The following code can be used to reproduce this error:
XSLT:
<xsl:value-of select="src:myFunction(foo)"/>
XML:
<foo>Some Text</foo>
Java:
public static String myFunction(org.w3c.dom.Node n) {
String s = n.getTextContent();
// s should be "Some Text", but is actually null.
}
