RegEx - Turn Plain Text Into Links..?

[cyfer65]

Im trying to make a greasemonkey scrip that turns all 4 digit numbers in plain text into a link on a site.I need some help with regex to find and replace all instances of plain text like this "___1234___" into links like<a href="http://site.com?ID=1234">1234</a> something like this, but not sure what the proper way to format it is to replace all the instances it finds..?var pattern = /___([0-9]{4})___/g;

string.replace(regexp/substr,newstring) Will replace every instance it finds if you use a /g flag which you have. So just go str.replace(/___([0-9]{4})___/g, "<a href=\"http://site.com?ID=$1\">$1</a>"). Good luck!

Thanks, so how do I get it to replace the text on the webpage though?arn't I suppose to get the whole html into a variable or something to search through..what is the str representing..?

It would help if you could say what the site is (I used to write GM scripts for 2 years). I'm guessing you're taking post id's? Well basically you take the element e.g. <p id="element">___1234___</p> var str = document.getElementById('element');str.innerHTML = str.innerHTML.replace(...);

this seemed to do the trick

document.body.innerHTML = document.body.innerHTML.replace

so how could I do the exact same thing except for IP Addresses..?they appear like this in the HTML Source Code.

___1.1.1.1</td>

This should work:

/___(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/

That's four numbers between one and three digits, separated by dots.
