Newbie alert... After a LOT of searching around (programming languages, libraries, toolkits, etc.) I have concluded that XPath is the best approach for my application. I found an implementation and my app is running fine. The only problem is that the app is rather slow, and I foresee the need for speed. See my imports below. The reason for the sluggish performance is that my XPath is based on DOM, and for every element retrieved the whole tree must be re-evaluated. Needless to say, that is very inefficient. Is there any XPath implementation based on SAX out there? Frankly, I don't even know where to start. Pointers would be very much appreciated. TIA, -Ramon ps: I only do retrieves, my XML files are large and read-only. ------------------------------ import javax.xml.xpath.XPath; import javax.xml.xpath.XPathConstants; import javax.xml.xpath.XPathExpressionException; import javax.xml.xpath.XPathFactory; import org.w3c.dom.Node; import org.w3c.dom.NodeList;
I am also interested in having XPath/DOM: (1) Read the whole XML tree, and keep in memory. (initialization stage) (2) Search the tree, as needed. (In fact, this sounds even better than SAX, if there is such thing ;-) -RFH --------------------------------------------------------------------- To unsubscribe, e-mail: j-users-unsubscr...@xerces.apache.org For additional commands, e-mail: j-users-h...@xerces.apache.org
