Re: Extract and modify IMG SRC tags in an HTML document.

in reply to Extract and modify IMG SRC tags in an HTML document.

Searching and replacing HTML can be tricky. For example, what about HTML like this:

<H1>Hello World</H1>
<IMG 
HEIGHT="20" WIDTH="20"
SRC="me.gif"
ALT="My picture!"
>
[download]

However, if you simply want to replace their picture with yours, use a regexp:

s/SRC="[^"]*"/SRC="$mypicture"/gi;
[download]

but you'll also want to remove and/or replace any WIDTH, HEIGHT, and ALT tags as well.

....which get real complicated real quick. Consider using a module to parse the html, or write your own little subroutine to parse each instance of the IMG tag...
