[SOLVED] Using regex to mask the SSN

[fletchsod]

It's been a while I haven't use regular express, so I need someone with a fresh mind on this one.  There is a SSN that is within the HTML tags or XML tags, so I only need to mask the SSN.  There may be or may not be whitespace(s) between the SSN and the html/xml tags.

 

IE -->  <SSN>111-11-1111</SSN>

    -->  <SSN> 111-11-1111</SSN>

    -->  <SSN> 111-11-1111 </SSN>

    -->  <SSN>    111-11-1111  </SSN>

 

Whatever happens, I need it to become like this...

 

IE --> <SSN>XXX-XX-1111</SSN>

 

Thanks...

I recommend an XML parser if you're doing other work; otherwise:

 

<pre>
<?php
$data = <<<DATA
IE -->  <SSN>111-11-1111</SSN>
    -->  <SSN> 111-11-1111</SSN>
    -->  <SSN> 111-11-1111 </SSN>
    -->  <SSN>     111-11-1111  </SSN>
DATA;
$data = preg_replace('%<SSN>\s*\d{3}-\d{2}-(\d{4})\s*</SSN>%', '<SSN>XXX-XX-$1</SSN>', $data);
echo htmlspecialchars($data);
?>
</pre>

Thanks..  It does work now.    I'm using this to update the received XML string before passing it on to MS-Access application and later the XML parser for the web browser.

P.S.  How do I mark it as solved?

Via "Topic Solved" in the bottom left corner, after the last post.

Gotcha!  Just click that "Topic Solved" folder tab and voila!    Thanks...
