I am creating a parser that wards off against spamming
and harvesting of emails from a block of text that comes from tinyMCE (so it may or may not have
html tags in it)
I've tried regexes
and so far this has been successful:
/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i
problem is, i need to ignore all email addresses with mailto hrefs. for example:
<a href="mailto:
[email protected]">
[email protected]</a>
should only return the second email add.
To get a background of what im doing, im reversing the email addresses in a block so the above example would look like this:
<a href="mailto:
[email protected]">moc.liam@tset</a>
problem with my current regex is that it also replaces the one in href. Is there a way for me to do this with a single regex? Or do i have to check for one then the other? Is there a way for me to do this just by using gsub or do I have to use some nokogiri/hpricot magicks
and whatnot to parse the mailtos? Thanks in advance!
Here were my references btw:

so.com/questions/1376149/regexp-for-extracting-a-mailto-address
im also testing using this:

edit
here's my current helper code:
def email_obfuscator(text)
text.gsub(/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i) { |m|
m = "<span class='anti-spam'>#{m.reverse}</span>"
}
end
which results in this:
<a target="_self" href="mailto:<span class='anti-spam'>moc.liamg@tset</span>"><span class="anti-spam">moc.liamg@tset</span></a>
