Okay. Then like Geir said, try dom4j. It can convert DOM to dom4j's node
model. See http://www.dom4j.org/cookbook/cookbook.html#NB2C for more
info. Also, if jTidy can generate SAX events you could have dom4j read
those from jTidy.

Another option is to write a little class that implements Iterator and
given a DOM NodeList could traverse it.

At the moment, the DOM document is generated by JTidy, because it 'cleans it up' before I work with it. So back go the original question: How can I iterate through a NodeList with #foreach()?

Not certain if this will answer your question as to why foreach isn't working as you expect it to, but Jaxen (http://jaxen.org/) can help you work with XML object-models (DOM, JDOM, dom4j, EXML). Using XPath, you can extract whatever data portions you need. If you like JDOM, then Anakia (part of Velocity) is also a nice way to go. SomeDay(tm), I plan on re-working Anakia to use Jaxen instead of werken.xpath, so that more than just JDOM is supported. -bob -- To unsubscribe, e-mail: <mailto:velocity-user-unsubscribe@xxxxxxxxxxxxxxxxxx> For additional commands, e-mail: <mailto:velocity-user-help@xxxxxxxxxxxxxxxxxx>
