  1. POExtracting email addresses in an html block in ruby/rails
    text
    copied!<p>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)</p> <p>I've tried regexes and so far this has been successful:</p> <pre><code>/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i </code></pre> <p>problem is, i need to ignore all email addresses with mailto hrefs. for example:</p> <pre><code>&lt;a href="mailto:test@mail.com"&gt;test@mail.com&lt;/a&gt; </code></pre> <p>should only return the second email add. </p> <p>To get a background of what im doing, im reversing the email addresses in a block so the above example would look like this:</p> <pre><code>&lt;a href="mailto:test@mail.com"&gt;moc.liam@tset&lt;/a&gt; </code></pre> <p>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!</p> <p>Here were my references btw:</p> <p>so.com/questions/504860/extract-email-addresses-from-a-block-of-text</p> <p>so.com/questions/1376149/regexp-for-extracting-a-mailto-address</p> <p>im also testing using this:</p> <p><a href="http://rubular.com/" rel="nofollow noreferrer">http://rubular.com/</a></p> <p><em>edit</em></p> <p>here's my current helper code:</p> <pre><code>def email_obfuscator(text) text.gsub(/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i) { |m| m = "&lt;span class='anti-spam'&gt;#{m.reverse}&lt;/span&gt;" } end </code></pre> <p>which results in this:</p> <pre><code>&lt;a target="_self" href="mailto:&lt;span class='anti-spam'&gt;moc.liamg@tset&lt;/span&gt;"&gt;&lt;span class="anti-spam"&gt;moc.liamg@tset&lt;/span&gt;&lt;/a&gt; </code></pre>
