Regexp parsing prоblem

Question

There is a block div, in him an unknown number of links like "a href onclick", if there are link more one, then they are separated a comma and a space.

var reg = /<div class="labeled fl_l"><a href="[^"]*" onclick="[^"]*">(.+?)<\/a>(, <a href="[^"]*" onclick="[^"]*">(.+?)<\/a>{1,})?<\/div>/mg;
var arr;
while ((arr = reg.exec(data)) != null) {
            console.log(arr[0]); //contains the entire text (because it is java script)
    console.log(arr[1]); //contains the name of the first link
    console.log(arr[2]); //contains the following "a href" entirely (if I will point out (?: x, <a... /a>), then the nested brackets will not work)
    console.log(arr[3]); //contains the name of the second link, **and then all of the code**
}

}

I think that should be used ([^ <] *) instead of (. +?), but it does not work at all then.

I'll stop you right away. It's time for you to know the thruth... http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags — plalx, Sep 30 '13 at 20:19
Aside from plalx's comment, if you are going to ask a question about a regex, at least give some examples of the source and what you expect to extract. Then forget regex and use the DOM manipulation functions in Javascript that are designed for the purpose. — Matt Burland, Sep 30 '13 at 20:20
Don't parse HTML with a regular expression. You're in JavaScript, don't you have access to the DOM elements themselves? It's already parsed, you just need to access it. — tadman, Sep 30 '13 at 20:24
Start with `getElementByClass` to get the parent div and then `getElementByTagName` to get all the `A` tags. Then you can use `getAttributeNode` to get whatever attributes you are interested in. — Matt Burland, Sep 30 '13 at 20:27

If using regular expressions were ideal for this (which they aren't), I'd go with two separate expressions, one to find everything between <div class="labeled fl_l"> and </div> and then another to find each link.

However, regular expressions aren't the right tool for the job. You might want to instead consider using xPath to iterate through the links.
