LSSerializer fails when validating external entities with namespaces
--------------------------------------------------------------------
Key: XERCESJ-1043
URL: http://issues.apache.org/jira/browse/XERCESJ-1043
Project: Xerces2-J
Type: Bug
Components: SAX
Environment: Linux Debian
Reporter: ijorge
Priority: Minor
When I try to write a Document with this code:
System.setProperty(DOMImplementationRegistry.PROPERTY,
org.apache.xerces.dom.DOMImplementationSourceImpl");
DOMImplementationRegistry registry = DOMImplementationRegistry.newInstance();
DOMImplementationLS impl
=(DOMImplementationLS)registry.getDOMImplementation("LS");
LSOutput output = impl.createLSOutput();
output.setSystemId(uri);
LSSerializer writer = impl.createLSSerializer();
writer.write(document, output);
I recieve this error:
[java] java.io.IOException: The replacement text of the entity node
'entity' contains an element node 'example1' with an attribute 'xmlns:exa' an
undeclared prefix 'xmlns'.

These are the xml files that I am using:
XML:
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE Root PUBLIC "-//Example//DTD Example/EN"
"http://www.example.com/example"; [
<!ENTITY entity SYSTEM 'entity.inc'>
]>
<Root
name="root"
xmlns="http://www.example.com/example";
xmlns:exa="http://www.example.com/example";>
&entity;
</Root>
ENTITY:
<?xml version="1.0" encoding="iso-8859-1"?>
<example1 xmlns:exa="http://www.example.com/example";>
<exa:example2>ss</exa:example2>
</example1>
I have been investigating the source code of Xerces and I think that the error
is in org/apache/xerces/util/NamespaceSupport.java. The method "String
getURI(String prefix)" compare two string but uses "==" instead of "equals". I
have modified this code and previous example does not produce errors.
DIFF between original code and my modified code:
232c232
< if (fNamespace[i - 2] == prefix) {
---
> if (fNamespace[i - 2].equals(prefix)) {
--
