seems to work fine How can I write a regular expression to return the value of the mesh volume? The file containing this information is printed below. , You could try something like this:
code :
%float_pattern = "[0-9.]+";
float_pattern = "\d+(?:\.\d+)?";
pattern = "Mesh Volume  is (?<MeshVolume>" + float_pattern + ")";

matches = regexp(information, pattern, 'match')
tokens = regexp(information, pattern, 'tokens')
names = regexp(information, pattern, 'names')

if isfield(names, "MeshVolume")
    fprintf("Mesh Volume = %f m^3\n", names.MeshVolume);
    fprintf("Failed to find mesh volume.\n");

it helps some times @diEcho and @Dve are correct, you should learn to use something like the native DOMdocument class rather than using regex. Your code will be easier to read and maintain, and will handle malformed HTML much better.
Here is some sample code which may or may not do what you want:
code :
$contents = '';
$doc = new DOMDocument();
$nodes = $doc->getElementsByTagName('div');
foreach ($nodes as $node)
      $attributes = $element->attributes;
         foreach ($attributes as $index=>$attr){
            if($attr->name == 'class' && $attr->value == 'rgz'){
               $contents .= $node->nodeValue;

I hope this helps you . Can you change the single quote to a unicode character /u0027 or use the ASCII \x27 and have it work properly?
