With this plugin you can define a PCRE regular expression against which data entered 
in XProfile fields will be matched.
For example:
<ul>
<li>check webpage field for a correct(-ish) URL or domain name: <code>%^(https?://)?([^ :/]{1,63}\.)+[^ :/.]{2,63}%iu</code></li>
<li>check age field for a sane(-ish) value (0-199): <code>/^1?[0-9]?[0-9]$/</code></li>
<li>check phone field for a sane(-ish) value: <code>/^+?[0-9 -]{7,45}$/</code></li>
<li>check any field for a minimum and maksimum length: <code>/^.{10,100}$/u</code></li>
</ul>
You can also configure a message to show when a field data does not validate.

Email Address Encoder


This might work with page or post content, but does not with widgets. I can't recommend using this and suggest to use the plugin "Email Encoder" by Jannis Thuemming instead, since that does the job out of the box.
