RE: What is fast ?
In order to manipulate the nodes of DOM you need to run a query to select the nodes that are subject to manipulation, which involves XPath processor, which in case of MS DOM is encapsulated by selectNodes() method. Then you need to iterate over the returned list of nodes to do the actual modification. If you already have reference to these nodes that are to be modified as a result some earlier processing, that you don't run the above query and it may be quite fast to modify them. However, if you can quickly modify the underlying xml text, though somewhat less elegant - read less elegant as euphemism for hack - then parsing the modified xml text into a new modified DOM might turn to be faster. The actual difference might be implementation dependent. cheers roman -----Original Message----- From: raghavendra.ml [mailto:raghavendra.ml@m...] Sent: Friday, February 01, 2002 2:17 PM To: Xml-Dev Subject: What is fast ? Hi, I need to replace 10-20 keywords in a DOM (the keys could be there in DOM as text nodes or attribute values in any node at any level). DOM is relatively small in size (say 50-60 nodes all levls included).The replaced DOM is used by some other process. Given the scenario .. whats faster ? Going through DOM for each possible text value (in Node or node attribute) and replace that text which could contain any of the keys and replacing the text or Replace all keywords in the xml string and then make a DOM out of it Or is there any other way much faster than both ? Please note the Keywords could also be repeated. Could somebody help me in making the decision ? Appreciate any comments .
