wish helps you Using JavaScript regexes. , you can use the following function:
code :
function extractInfo(str) {
    var myRegex = /\$(.*):([^$]*)/gm; 
    var match = myRegex.exec(str);
    while (match != null) {

      var key = match[1];
      var value = match[2];
      console.log(key,":", value);
      match = myRegex.exec(str);
}}  
var textualInfo = "$Label1: Text1\n    Text1 possibly continues \n$Label2: Text2\n$Label3: Text3 \n     Text3 possibly continues";
extractInfo(textualInfo);
[Log] Label1 :  Text1
    Text1 possibly continues 

[Log] Label2 :  Text2

[Log] Label3 :  Text3 
     Text3 possibly continues

Any of those help Just use DOM, it's easy enough:
code :
$dom = new DOMDocument;
$dom->loadXML($xml_string);

$documents = $dom->getElementsByTagName('Document');
foreach ($documents as $document) {
    echo $document->getAttribute('id');     // id1    

    $impacts = $document->getElementsByTagName('impact');
    foreach ($impacts as $impact) {
        echo $impact->getAttribute('for');  // tree.def
        echo $impact->getAttribute('name'); // Something has changed
    }
}
Regex & PHPUnit assertion : count how many times word matches in repeating pattern

To fix this issue I'm using PHPUnit to test the output of a PHP function that produces HTML option tags using provided data. , Don't use regexes to parse HTML or XML documents. Use a DOM parser:
code :
// create a document object from the HTML string
$doc = new DOMDocument();
$doc->loadHTML($html);

// create a XPath selector
$selector = new DOMXPath($doc);

// select nodes containing the selected attribute
$result = $selector->query('//*[@selected]');

// make assertion
$this->assertEquals(1, $result->length, 'Failed to assert that result contains exactly one selected element');

Does that help I'm being destroyed by spam and the emails are always different except that they always have similar links like this that repeat several times: , I believe I've improved on your pattern slightly:
code :
/(\/\w{30,})(?:.+?\1){3,}?/s

I wish this helpful for you Interesting requirement. Code is explained in the comments, a very fast solution using only REGEX:
code :
import re
# make it more complex
text = "export1/VB European0/NNP export/VB European1/NNP Community1/NNP Community2/NNP French/JJ European2/NNP export/VB European2/NNP"


# 1: First clean app target words word/NNP to word,
#  you can use str.replace but just to show you a technique
# how to to use back reference of the group use \index_of_group
# re.sub(r'/NNP', '', text)
# text.replace('/NNP', '')
_text = re.sub(r'(\w+)/NNP', r'\1', text)

# this pattern strips the leading and trailing spaces
RE_FIND_ALL = r'(?:\s+|^)((?:(?:\s|^)?\w+(?=\s+|$)?)+)(?:\s+|$)'
print('RESULT : ', re.findall(RE_FIND_ALL, _text))
  RESULT :  ['European0', 'European1 Community1 Community2', 'European2', 'European2']
import re
# make it more complex
text = "export1/VB Europian0/NNP export/VB Europian1/NNP Community1/NNP Community2/NNP French/JJ Europian2/NNP export/VB Europian2/NNP export/VB export/VB"

RE_SPLIT = r'\w+/[^N]\w+'
result = [x.replace('/NNP', '').strip() for x in re.split(RE_SPLIT, text) if x.strip()]
print('RESULT:  ', result)

wish help you to fix your issue You are looping 10 times with for x in range(0,10, 1):
So the single match is printed 10 times.
