I'm working on a regular expression to do syntax highlighting and I just ran
into a problem.
The regular expression below works on just about everything except nested
parentheses:
(</*cf\w+)\s*((?:\w+\s*?)|(?:\w+\s*=\s*["'][^"']*["']\s*?)|(?:\w+\([^)]+\)))*(/*>)
Will match:
<cfif isDefined('form.fieldnames')>
<cfheader name="Content-Type" value="text/xml">
<cfcontent type="text/xml" reset="yes">
<cfset lacking = "">
<cfloop list="#form.fieldnames#" index="i">
<cfif not listLen(lacking)>
but not
<cfif not isNumeric(evaluate(i))>
I'm not sure what to do about nested parens because nested functions can get
pretty complex :/ Any thoughts?
This is the block that is supposed to deal with those: (?:\w+\([^)]+\))
Oh yeah, and is there any way to make the 2 key/value pairs in the following
tag show up as separate matches? At the moment, the index="i" capture
overwrites the first pair. Or do I just need to loop over an exec to handle
those separately?
<cfloop list="#form.fieldnames#" index="i">
