No, if you omit a prefix from an element name in an xpath, you tell the
xpath processor the element you want is in no namespace.
As far as I can tell, the prefix resolver is only called on the xpath (not
on nodes of the document). So you might provide a prefix resolver extending
PrefixResolverDefault which knows the mappings of a certain set of prefixes
which you use in your xpath, and lets the default resolver's method handle
all others.
class MyPrefixResolver extends PrefixResolverDefault {
private HashMap prefixes;
public MyPrefixResolver(HashMap namespaceByPrefix, Node context) {
super(context);
prefixes = namespaceByPrefix;
}
public String getNamespaceForPrefix(prefix}{
String ns = (String)prefixes.get(prefix);
if (ns != null) return ns;
return super(prefix);
}
etc. -- other methods as needed
}
You might have to use ugly prefixes to attempt to avoid clashes with
prefixes that might appear in a document created by someone else with
another namespace as their resolution.
