FnC

Ok, let’s try this…
This is actually a reply to the post mentioned above, but that one has been closed.

So what we did was this:

1.) Open glossary.php

2.) Near the top, add a function glossaryXmlEntities that scans for that unknown nbsp entity and replaces it

function glossaryXmlEntities($str) {
 $xml = array('(AMP)#160;');
 $html = array('(AMP)nbsp;');
 $str = str_replace($html,$xml,$str);
 $str = str_ireplace($html,$xml,$str);
 return $str;
} 

(Replace all “(AMP)” with an ampersand when you copy this)

3.) Replace line 115 …

 $dom->loadXML($content_temp); 

… with this:

 $dom->loadXML(glossaryXmlEntities($content_temp)); 

and thats it.

4.) As I mentioned earlier, the warning also appears whenever another unknown entity is found. So our new function glossaryXmlEntities should actually look like this:

function glossaryXmlEntities($str) {
  $xml = array('(AMP)#160;','(AMP)#161;','(AMP)#162;','(AMP)#163;','(AMP)#164;','(AMP)#165;','(AMP)#166;','(AMP)#167;','(AMP)#168;','(AMP)#169;','(AMP)#170;','(AMP)#171;','(AMP)#172;','(AMP)#173;','(AMP)#174;','(AMP)#175;','(AMP)#176;','(AMP)#177;','(AMP)#178;','(AMP)#179;','(AMP)#180;','(AMP)#181;','(AMP)#182;','(AMP)#183;','(AMP)#184;','(AMP)#185;','(AMP)#186;','(AMP)#187;','(AMP)#188;','(AMP)#189;','(AMP)#190;','(AMP)#191;','(AMP)#192;','(AMP)#193;','(AMP)#194;','(AMP)#195;','(AMP)#196;','(AMP)#197;','(AMP)#198;','(AMP)#199;','(AMP)#200;','(AMP)#201;','(AMP)#202;','(AMP)#203;','(AMP)#204;','(AMP)#205;','(AMP)#206;','(AMP)#207;','(AMP)#208;','(AMP)#209;','(AMP)#210;','(AMP)#211;','(AMP)#212;','(AMP)#213;','(AMP)#214;','(AMP)#215;','(AMP)#216;','(AMP)#217;','(AMP)#218;','(AMP)#219;','(AMP)#220;','(AMP)#221;','(AMP)#222;','(AMP)#223;','(AMP)#224;','(AMP)#225;','(AMP)#226;','(AMP)#227;','(AMP)#228;','(AMP)#229;','(AMP)#230;','(AMP)#231;','(AMP)#232;','(AMP)#233;','(AMP)#234;','(AMP)#235;','(AMP)#236;','(AMP)#237;','(AMP)#238;','(AMP)#239;','(AMP)#240;','(AMP)#241;','(AMP)#242;','(AMP)#243;','(AMP)#244;','(AMP)#245;','(AMP)#246;','(AMP)#247;','(AMP)#248;','(AMP)#249;','(AMP)#250;','(AMP)#251;','(AMP)#252;','(AMP)#253;','(AMP)#254;','(AMP)#255;');
  $html = array('(AMP)nbsp;','(AMP)iexcl;','(AMP)cent;','(AMP)pound;','(AMP)curren;','(AMP)yen;','(AMP)brvbar;','(AMP)sect;','(AMP)uml;','(AMP)copy;','(AMP)ordf;','(AMP)laquo;','(AMP)not;','(AMP)shy;','(AMP)reg;','(AMP)macr;','(AMP)deg;','(AMP)plusmn;','(AMP)sup2;','(AMP)sup3;','(AMP)acute;','(AMP)micro;','(AMP)para;','(AMP)middot;','(AMP)cedil;','(AMP)sup1;','(AMP)ordm;','(AMP)raquo;','(AMP)frac14;','(AMP)frac12;','(AMP)frac34;','(AMP)iquest;','(AMP)Agrave;','(AMP)Aacute;','(AMP)Acirc;','(AMP)Atilde;','(AMP)Auml;','(AMP)Aring;','(AMP)AElig;','(AMP)Ccedil;','(AMP)Egrave;','(AMP)Eacute;','(AMP)Ecirc;','(AMP)Euml;','(AMP)Igrave;','(AMP)Iacute;','(AMP)Icirc;','(AMP)Iuml;','(AMP)ETH;','(AMP)Ntilde;','(AMP)Ograve;','(AMP)Oacute;','(AMP)Ocirc;','(AMP)Otilde;','(AMP)Ouml;','(AMP)times;','(AMP)Oslash;','(AMP)Ugrave;','(AMP)Uacute;','(AMP)Ucirc;','(AMP)Uuml;','(AMP)Yacute;','(AMP)THORN;','(AMP)szlig;','(AMP)agrave;','(AMP)aacute;','(AMP)acirc;','(AMP)atilde;','(AMP)auml;','(AMP)aring;','(AMP)aelig;','(AMP)ccedil;','(AMP)egrave;','(AMP)eacute;','(AMP)ecirc;','(AMP)euml;','(AMP)igrave;','(AMP)iacute;','(AMP)icirc;','(AMP)iuml;','(AMP)eth;','(AMP)ntilde;','(AMP)ograve;','(AMP)oacute;','(AMP)ocirc;','(AMP)otilde;','(AMP)ouml;','(AMP)divide;','(AMP)oslash;','(AMP)ugrave;','(AMP)uacute;','(AMP)ucirc;','(AMP)uuml;','(AMP)yacute;','(AMP)thorn;','(AMP)yuml;');
  $str = str_replace($html,$xml,$str);
  $str = str_ireplace($html,$xml,$str);
  return $str;
}

(Again, replace all “(AMP)” with an ampersand when you copy this)

This version covers all encoded characters from #160 to #255. If you need something beyond that (like mathematical or greek characters), you may have to add them as well. This list here can be used for reference: http://www.w3.org/TR/html4/sgml/entities.html#h-24.3.1

Hope we could help.
