    Replacing <br> with line breaks

    I have this working, but I would like to take it one step further. Most of my content has two <br /> tags in a row to space out sentances. This is not how I want, but this is how it is. Since I load this content up into a textarea, I need to strip the <br /> tags and replace them with line breaks so the user does not see the break tags, I use:

    Code:
    replace(/<br \/>/g, "\n");
    My problem comes because there are two (<br /><br />) tags right after one another, so the replace function creates two line breaks, which I don't want. Is there a way to check if there are two break tags, and if there are, only replace them with one line break?

    put the tag inside a parenthesis so you can check one or more times the pattern:
    Code:
    replace(/(<br \/>)+/g, "\n");

    Or to make it work for HTML and XHTML, e.g.:
    Code:
    <br>HTML (not XHTML).
    OR
    <br/>No space.
    OR
    <br />Single space.
    OR
    <br            />Multiple spaces.
    OR
    <br	/>Single tab instead of multiple spaces.
    Code:
    replace(/(<br\s*\/?>)+/g, "\n");
    Of course, it replaces any number of those with any combination of whitespace characters before the "/>" or the ">", depending on whether it is <br/> or <br> respectively.
