Re: [dom4j-user] Selecting by id

[Evan Kirkconnell]

Well, I gave that a shot and it was much faster.  I looked at the code, because I don't want to capitalize my xhtml, and it's just walking the tree.  I was thinking it'd be maintaining a hashtable or something.  Makes you wonder why jaxen's so much slower...  So, I'll probably just write my own walking function that looks for the lower case id.  Here's the code I looked at: Thanks Edwin, --Evan     public Element elementByID(String elementID) {         for (int i = 0, size = nodeCount(); i < size; i++) {             Node node = node(i);             if (node instanceof Element) {                 Element element = (Element) node;                 String id = elementID(element);                 if ((id != null) && id.equals(elementID)) {                     return element;                 } else {                     element = element.elementByID(elementID);                     if (element != null) {                         return element;                     }                 }             }         }         return null;     }     protected String elementID(Element element) {         // XXX: there will be other ways of finding the ID         // XXX: should probably have an IDResolver or something         return element.attributeValue("ID");     } Edwin Dankert wrote: I'm curious as to why the dom4j function elementByID does not work. It seems like this should be independent of Jaxen. Actually, you are totally right ... I just had a look at the implementation and it should indeed work ... the elementByID method does not try to find elements with attributes which have been specified as having the ID type but attributes with a name of "ID". (make sure to use capitals) Regards, Edwin
