php - Replace HTML entities between divs and only between divs -


given following string:

asd &nbsp; <div> def &nbsp; foo &nbsp; </div> ghi &nbsp; <div> moo &nbsp; </div>

i want remove of &nbsp;'s within <div>s, resulting in:

asd &nbsp; <div> def  foo  </div> ghi &nbsp; <div> moo  </div>

i can use standard php stuff, i'm not sure how approach problem. couldn't figure out how keep contents inside <div>s while removing &nbsp;

the reason why need because wordpress's content filter adds &nbsp; under strange situations. can't remove &nbsp; because might've been entered user, need remove of them within element that's having display problems caused them

the following works in case: 

$str = "asd &nbsp; <div> def &nbsp; </div> ghi &nbsp; <div> moo &nbsp; </div>"; $res = preg_replace("%<div>(.*?)&nbsp;(.*?)</div>%", "<div>$1$2</div>", $str);

but beware of facts:

  • it won't work if divs have attributes;
  • it won't work expected if divs nested;
  • it applies replacement of &nbsp; 1 time, multiple &nbsp;s inside divs untouched.

so abovementioned replacement not solution @ all. it's way better first find div tags (xml) parser function , replace &nbsp;s.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
