This might help you I have a simple pattern I am trying to match, any characters captured between parenthesis at the end of an HTML paragraph. I am running into trouble any time there is additional parentheticals in that paragraph: , Just change the expression to non-greedy and reverse the match order:

I wish did fix the issue. Since you're iterating through it all, I'd say you should still do that, but go the other way around. Find the smallest subsets of paranthetical expressions, rather than the largest ones:
code :
(\([^(]+\))
(5 + (4 + 0,75 + 6 + 2)) + 3

Does that help You can just try to remove the non-numeric and "." characters from your string. Try regex replace with this expression: "[^0-9\.]"
Code
code :
QRegExp rx("[^0-9\\.]");
yourString.replace(rx, "");

help you fix your problem Do not use regex to parse HTML. Ever.
Learn what xpaths are, and you will be much better off (xpaths can be used in many languages). Python has eTree built in which will do fine on your example, but lxml is a much better libary (with a mostly-compatible interface).
code :
In [1]: import lxml.html

In [2]: html = lxml.html.fromstring("""<span id="target_text">
   ...:          sample text
   ...:          <span class="red"> word1 </span>
   ...:          <span class="green"> <b> word2 </b> word3 </span>
   ...:          <b> word4 </b>
   ...:          <span> word5 </span>
   ...:          <b> word6 </b>
   ...:          <a class="itlink" href="http:www.example.com" > Details </a>
   ...: </span>""")

In [3]: html.xpath('//span[@id="target_text"]')[0].text_content()
Out[3]:' \n         sample text\n          word1 \n           word2  word3 \n          word4 \n          word5 \n          word6 \n          Details \n'
In [9]: content = html.xpath('//span[@id="target_text"]')[0].text_content()
In [10]: import re
In [11]: re.sub('\s+', ' ', content).strip()
Out[11]: 'sample text word1 word2 word3 word4 word5 word6 Details'

should help you out Don't parse HTML with regex.
If you want to extract data from HTML, use XPath.
code :
XPathExpression expr = xpath.compile("//p/a[@class='related-article']");
NodeList list = (NodeList)expr.evaluate(doc, XPathConstants.NODESET);
foreach(Node node in list)
{
    string text = node.InnerText;
    string href = node.Attributes["href"].Value;
}
