Re: [OT] Newbie Question:XML parsing
I'll third the recommendation to use Digester. I needed to parse an XML file for the securityfilter project, and I had not done any XML parsing before so I was expecting it to be a fair amount of work to do. Then I recieved a contributed solution from a member of this list that used Digester. It only took me a few minutes of looking at the code to understand how it worked. Digester is great for the kind of config-file parsing that my project needed. Here's a link to the class that uses Digester to parse the securityfilter config file (see the loadConfig() method for the Digester part): http://tinyurl.com/dj54 Having struggled with some software that used XML for configuration but had no DTD before (what the heck can I specify, and how?), I decided to write a DTD for the config file for my project. I used XML Spy to create the DTD pretty quickly, despite not having any experience with authoring DTDs before. The DTD language has some annoying limitations (which seems to explain why many projects/products don't use a DTD for their config files), but I was able to come up with a DTD that worked for my needs. Now that I had a DTD, Digester could validate it during the parse. Digester also allows you (as the developer of the software that reads the XML file) to register a local copy of the DTD for validation, rather than retrieving it from the internet. You can also turn validation on or off, a feature you may want to allow the users of your project to control. -Max - Original Message - From: "Navjot Singh" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Wednesday, June 04, 2003 11:55 PM Subject: RE: Newbie Question:XML parsing > you may wish to see apache digester. > > |-Original Message- > |From: Sushil Jain [mailto:[EMAIL PROTECTED] > |Sent: Sunday, June 05, 1994 9:38 AM > |To: Struts Users Mailing List > |Subject: Newbie Question:XML parsing > | > | > |I am new to Struts.

RE: Newbie Question:XML parsing
If you want to just read the file and validate it against some rules, then may be you need to write a dtd/schema for the file and just read teh file using xerces or some other parser while setting the validate feature true...That is simple and easy..Apart from writting the xml schema /dtd part..:-)) But if you need to populate java objects from the xml file contents, have a look at Castor.It eliminates the need to know jaxp at all.. If you need any more help,let me know. regards, Shirish -Original Message- From: Andrew Hill [mailto:[EMAIL PROTECTED] Sent: Thursday, June 05, 2003 6:25 AM To: Struts Users Mailing List Subject: RE: Newbie Question:XML parsing Nah, thats really a job for your parser. Struts does come with a marvellous thing called "Digester" (which is part of the commons project) but thats used for creating objects (usually for configuration (its used in struts to process struts-config)) so is probably not applicable to what your trying to do.
