使用Javascript（regex）查找不在HTML标记内的文本

Question

I have a string from a DOM element, which contains something similar to the following:

<span class='greenhornet'>Can you catch the green?</span>

I need to know the position of the word green .

In this case, if I setup a pattern /green/ , JS exec() of course will return the first occurrence of green (position 13).

Is there a way to tell JS regexp to ignore ! the word green , if it's between < and > or is there an easier way to do this?

Oh, and I can't just strip the HTML either!

thanks.

Answer 1

As the commentors (and user1883592) have suggested, stripping the HTML or parsing the text out of the HTML is the correct answer here. Using regular expressions with HTML is a loser's game; you've been warned.

But, that being said, if you really want to play that game, I'd start by ensuring there are no opening brackets in between your term and the last closing bracket; in other words:

var greenRegex = />[^<]+(green)/;
var position = "<span class='greenhornet'>Can you catch the green?</span>".search(greenRegex);
// position = 25, not 13

Answer 2

You can get innerHTML of the span element. No Regex needed.
