RE: RegEx to manipulate html tags

For example, I would want to replace the SRC parameter of an IMG tag but the SRC parameter is not located in the same postition of the IMG tag each time. So, as an example: img src=image1.jpg img height=100 width=100 src=image1.jpg should both be converted to: img src=image2.jpg img height=100 width=100 src=image2.jpg If the SRC parameter were always located after the IMG tag start (as in the first example) then I could use a simple findnocase but that's not the case.

Re: RegEx to manipulate html tags
Hi, This is an application for CF_REextract; see: http://www.contentbox.com/claude/customtags/REextract/testREextract.cfm?p=hf You could easily get all img tags in a recordset, then loop on the query and analyse them, still using CF_REextract. -- ___ REUSE CODE!

Re: RegEx to manipulate html tags
Thanks for all of the replies but what I really need to do is append some text in the SRC value. What I mean is to change this: img src=image1.jpg to img src=/root/images/image1.jpg I would like to do this for all images in the text and account for both single and double quotes.

Re: RegEx to manipulate html tags
what I really need to do is append some text in the SRC value. Since CF_REextract also returns the exact position and length of every string in the text searched, these strings can easily be changed, replaced or appended. The trick is to loop backward in the query to make sure the positions of all strings are not changed before. -- ___ REUSE CODE!

Re: RegEx to manipulate html tags
OK, I'll take a look at this. I read the info on your site and it seems a bit daunting to a non-regex person :) Thanks, Howie --- On Wednesday, April 27, 2005 11:18 AM, Claude Schneegans scribed: --- what I really need to do is append some text in the SRC value.

Re: RegEx to manipulate html tags
I read the info on your site and it seems a bit daunting to a non-regex person It may looks so, but on the contrary, it is based on the principle that it may sometimes be much easier to find a string based on context before and after than using only one single regex. Then it actually makes thing easier for a non-regex person. -- ___ REUSE CODE!

Do you just want to get the src or are you interested in all the attributes? If just the source then something like this should do it: #ReReplaceNoCase(Input, (img.*?src.*?=.*?).*?(.*?), \1#NewSource#\2)# You'll have to tweak it. I'm not even sure it'll run - but I think it will! The power of positive thinking! You'll have to make it more complex to also understand things like single quotes instead of double quotes. If you want ALL of the attributes then a nice (but, honestly, slow) way to do it is to find all of the img tags (a regex like img.*? should do that) rip them out of the source and treat each one like an XML doc (using XMLParse()). You can then navigate the tag and its attributes like an XML document. This will only work on well formed code (so you might have to insert an end slash if its not there.
