| <P> | |
| The methods in this class are convenience methods into the | |
| low-level XPath API. | |
| These functions tend to be a little slow, since a number of objects must be | |
| created for each evaluation. A faster way is to precompile the | |
| XPaths using the low-level API, and then just use the XPaths | |
| over and over. | |
| NOTE: In particular, each call to this method will create a new | |
| XPathContext, a new DTMManager... and thus a new DTM. That's very | |
| safe, since it guarantees that you're always processing against a | |
| fully up-to-date view of your document. But it's also portentially | |
| very expensive, since you're rebuilding the DTM every time. You should | |
| consider using an instance of CachedXPathAPI rather than these static | |
| methods. | |

| <DD>Evaluate XPath string to an XObject. | |
| XPath namespace prefixes are resolved from the namespaceNode. | |
| The implementation of this is a little slow, since it creates | |
| a number of objects each time it is called. This could be optimized | |
| to keep the same objects around, but then thread-safety issues would arise. | |
