I suck at RegEx

I suck at RegEx

I suck at RegEx

(OP)
Can someone please help me.

I have an html tag:

CODE

<div id="myid" class="myclass " data="QAZwsxedc12345.pdf" data-height="100" data-width="100"> 

I'm trying to use regex to find this div which has a unique id and I want to strip out the data portion that has the PDF file name.

I was trying

CODE

<div\sid=\"myid\"\sclass=\"myclass\s\"\sdata=\"[a-zA-Z0-9].pdf\" 

I'm not getting anywhere and I'm useless at regex. I simply want to find a <div match id="myid" then get the value contents of data=""

Thanks

NATE

RE: I suck at RegEx

Hi

Like this ?

CODE --> PHP CLI

php > var_dump(preg_match('/<div\sid=\"myid\"\sclass=\"myclass\s\"\sdata=\"([a-zA-Z0-9]+\.pdf)\"/', '<div id="myid" class="myclass " data="QAZwsxedc12345.pdf" data-height="100" data-width="100">', $match), $match);
int(1)
array(2) {
  [0] =>
  string(57) "<div id="myid" class="myclass " data="QAZwsxedc12345.pdf""
  [1] =>
  string(18) "QAZwsxedc12345.pdf"
} 
  • There are more than 1 alphanumeric characters before the ".pdf" extension, so use a + quantifier
  • The dot ( . ) is a metacharacter so escape it with backslash ( \ )
