volunteer? :)

RE: REReplace and RegExp
Someone will have to submit it. Considering Rob and I are already
_swamped_ under the queue now, it would be better if someone were to
submit this. I just can't bring myself to make the queue bigger. I'll
let others do that. ;)
Just as an FYI - both Rob and I know the queue is getting a bit backed
up now. Rob is very busy, and I've been working on a little product you
may have heard of. (It's does dynamic web page crap. ;) Once things
settle down, the queue will get busted down. Plus, we have some
interesting things in work for the site as well as a new site.

RE: REReplace and RegExp
James, Thanks for the response. It has given me other ideas about how to approach this. It appears that the solution you provided only replaces that Tags, which is part of the desired solution. I also need to obtain the value of the attributes and put then in differenct attributes for the tag. The real kicker is that the attributes in the tag can be in any order. For example: >From this: Oldenburg, Claes Thure,b.1929 Bruggen, Coosje van, b.1942 To this: Oldenburg, Claes Thure, b.1929 Bruggen, Coosje van, b.1942 So far, I've come up with this, which is not complete: REReplaceNoCase( agentList, '(.[^<]*?)', '\4', "ALL")> Background: I am using ColdFusion 4.51 on a Windows2000/IIS5 server. The tags come from an XML document that looks like this: 60793 Parc Andre-Citroen Paris: Parks and Gardens, 1615-1992 lGxFR B343a A53ed05 Oldenburg, Claes Thure, b.1929 Bruggen, Coosje van, b.1942 Berger, Patrick, b. 1947 Viguier, Jean-Paul Jodry, Jean-Francois Clement, Gilles Provost, Alain Thanks, Troy -- Troy Simpson Applications Analyst/Programmer - MCSE, OCP DBA North Carolina State University Libraries Campus Box 7111 | Raleigh | North Carolina ph.919.515.3855 | fax.919.513.3330 [EMAIL PROTECTED] -Original Message- From: James Ang [mailto:[EMAIL PROTECTED]] Sent: Monday, April 22, 2002 5:45 PM To: CF-Talk Subject: RE: REReplace and RegExp Try this: REReplaceNoCase(agents, "(|[[:space:]]+[^>]*>)", "\1a\2", "ALL") I have tested this code on CFAS 5 on WinXP.

Re: REReplace and RegExp
Troy, What you need is a 2-part parser. There isn't an easy way unless you decide to use MS XML Parser or the Apache.org Java parser to parse the XML. If you decided not to use the Apache or the MS XML parsers, here's how your tag parser would do: Step 1: Retrieve a start tag one at a time: ]*)> Step 2: Retrieve the individual attributes of the tag retrieved in step 1 Step 3: Perform transformation of the attributes in step 2. Step 4: Perform transformation of the tag in Step 1 Step 5: Place the transformed string back in to xml input stream OR place the transformed stream into your output stream. Step 6: If not end of file/stream, go to Step 1. Attached is a sample code that might help. It is meant for CFAS 5. I wrote it thinking that it would solve your problem until I re-read your posting. :P The attached file should provide some insight, I hope. :) For the code to work in CFAS 4.5.x, you will need to convert the UDF to Custom Tags. Good luck. :) Back to *real* work. (This list is too much fun.) James Ang Senior Programmer MedSeek, Inc.

RE: REReplace and RegExp
James, Thanks again. Great food for thought. Is there a performance hit with either of the XML Parsers you suggested? If so, what has been your experience? Do these XML Parsers use something called "XPath" to get the data from the XML Document? Background: I have created a pre-joined resultset of all the records() and stored them in an Oracle9i Table (a.k.a Materialize View). This basically takes all the records and joins them together into a denormalized spreadsheet to elliminate the expensive joins at runtime. One of the columns in my Table contains an XML Document compiled from all the tables and columns used for TEXT indexing and searching. Like I said, the documents are stored in an Oracle9i database table column as an XML document of type XMLType (clob or Character Large Object). There is some functionality in the database to parse the XML Document but as of now, I do not know how elaborate or expansive these functions are. Ideally, I am trying to make the Oracle9i Database do the work for me before returning the result set to the ColdFusion Application Server for processing. So far I've been able to get a list of tags for all my in a . I wonder if the XML functionality in the Oracle9i database exist and is as good as that of the two parsers you suggested? I also have the option to store the values in seperate columns. The problem I am running into is that mutliple can exist for each and I only want one record in the table(a.k.a Materialized View) for each .

RE: REReplace and RegExp
Here are the URL to the mentioned parsers: Java-based (AND C++,Perl,COM) for the Anti-MS camp: http://xml.apache.org/ Strictly COM-based for the those following the Dark M$ path: http://www.microsoft.com/xml/ The Apache XML Xalan Project supports Xpath in its latest iteration. MS XML 4.0 supports Xpath. Both of these implementations are pretty big and can have a performance hit at script/runtime. In my opinion, they would not scale properly if it is used on a page that gets hit a lot. Both implementations have memory leak issues on certain configurations (I have seen an early Apache parser dies after parsing and transforming 10,000 to 50,000 documents for a particular JVM that I can't remember off the top of my head). The MS XML stuff is notorious for memory leaks for certain pattern of usage. I am sure it has been reduced/eliminated with the latest iteration. I think you may have to batch the processing and store it somewhere. Have the batch run every so often to refresh the data. I doubt the Oracle dudes would do better than the Apache or the Microsoft XML teams. These two implementations are the best out there. I would not be surprised if Oracle used or incorporated a portion of the Apache parser. Good luck! :) James Ang Senior Programmer MedSeek, Inc.
