Hi all, I need to remove certain hyperlinks tags, which contain a certain "class" attribute, for instance: "<a href='http://link.com' class='js-removal'>link body</a>". The reason for it is that I want to keep all other hyperlinks ("href") tags and only remove those marked by a certain attribute (I was wondering to use the "class" attribute for that). Is there anyway to do that? Note: The current "removeElement(String element)" method only remove the entire element. It does not consider any attributes information. Thanks & Regards, Clelio de Souza |

For more advanced element processing, you'll probably want to implement your own filter class. It's probably a good idea to use the element remover filter as a starting point because when you want to remove an element you need to remove all of its children (and their children) in addition to the starting and ending element tags. There is more information about custom filters and how to use them in the documentation.

Or, rather than at parse time, you can manipulate the DOM using a NodeFilter
after the DOM has been created....
public class MyHrefFilter implements NodeFilter {
public final short acceptNode(final Node n) {
final String classVal = el.getAttribute("class");
if (classVal != null and classVal.indexOf("js-removal") > -1) {
el.removeAttribute("href");
return NodeFilter.FILTER_ACCEPT;
} else {
return NodeFilter.FILTER_SKIP;
}
}
}
Then in your application code....
Document myDocument = .....;
boolean expandEntityReferences = false;
NodeIterator iter =
((DocumentTraversal) myDocument).createNodeIterator(
myDocument,
NodeFilter.SHOW_ELEMENT,
new MyHrefFilter(),
expandEntityReferences);
//Must iterate in order to apply NodeFilter changes
while (iter.nextNode() != null);
iter.detach();
