RE: [ACFUG Discuss] XML & CF
Well, like I said, don't let the 30 pages scare you off. If you need (or want) to work with XML in CFML, just start reading the first few pages. That will give you great insight in and of itself. I just can't say enough about it. (Thanks, Teddy, for chiming in. And Chris, I wish you well with it also.) /Charlie http://www.carehart.org/blog/ _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, January 04, 2007 12:56 PM To: discussion@acfug.org Subject: Re: [ACFUG Discuss] XML & CF Good to hear.

RE: [ACFUG Discuss] XML & CF
What is a practical use for XML? What kind of situation would call for using it? _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Powell Sent: Monday, January 01, 2007 8:54 PM To: discussion@acfug.org Subject: Re: [ACFUG Discuss] XML & CF Also, I would suggest Jeff Peters' book on the CF XML Object: http://www.cafepress.com/protonarts.50984013 ap On Jan 1, 2007, at 8:31 PM, Andrew Powell wrote: 1.

If that is the case, then you can just manipulate that data in the array that xmlsearch() returns and then write the original xml back to a string with changes intact. I would not write it to an array of structs or a query if you're going to write back as XML to the server or database. Just manipulate the original XML doc and save the processing of conversion. To write it back to the server, you just toString(myXMLObj) within your CFFILE action="write" tag. On Jan 1, 2007, at 8:12 PM, [EMAIL PROTECTED] wrote: I've not really worked with XML and CF.

RE: [ACFUG Discuss] XML & CF
If you have control over the xml format, I would suggest just using the wddx tags to save and call up query info in a xml format that wddx uses.
