Hey, just a quick followup.
Since this is giving so much problems, what if:
1.- I get the content as text and not as DOM
2.- I apply the suggested functions so I can clean it up
3.- I load it into a DOM document with something like:
private Document load(String s) {
DocumentBuilder builder = factory.newDocumentBuilder();
return builder.parse(new StringBufferInputStream(s));
}
I guess this is not a too clean approach, but it seems this time Xindice is
taking me there...any better ideas?
I need some sleep now...
