+2 A:

I assume this means you want:

<option value="14">Foobar</option>

To become:

<option value="Foobar">Foobar</option>

If so, here's the Javascript. I assume the select variable contains the surrounding <select> tag DOM element, e.g. by form.nameOfselect.

for ( var option : select.options ) {
   option.value = option.text;
}

I am using textwrangler on Mac OS X and it can regex for its search/replace function.Sorry I did not mention that.

Answer 3

+3 A:

Just remove the value attributes. <option> by default takes a value of it's content.

<option value="Accounting">Accounting</option>

is equivalent to:

<option>Accounting</option>

Edit: using sed you can do

sed -r s/' value="[0-9]+"'//g

Quotes generally don't need to be escaped in a regex. This is a matter of the host language's string representation. For clarity you should leave it off if you are not referring to a specific implementation.

Ok ;-) Although I like expression "better safe, then sorry" ;-)

I think putting escape characters everywhere "just in case" is a bad thing, as it raises uncertainty which part of the processing chain (in your case shell->sed->regex) gets to see what. I'd rather have the pure regex, doing my own escaping than removing escaping someone else anticipated for me.

Answer 4

+1 A:

If your HTML is well-formed, this will do the trick:

Regex:

(?<=<option) value="\d+"

Replace with the empty string.

In HTML, option values fall back automatically to the displayed text, if no value attribute is present.

Answer 5

A:

It can be made a bit more general, but it works when there are no other attributes in the option tag:

/(.*")([^"]+)(">)([^<]+)(.*)/

Then replace the captured string with this:

$1$4$3$4$5

If you're using backslash as the subgroup reference character, replace the dollar signs with backslash.

Answer 6

A:

You've added that you want to perform the operation in a text editor. I wrote something assuming you'd want to use php, and I'll let it stand here because I think it's important.

Anyway, using TextWrangler (or any other text editor), replace

<option value="[^"]*">([^<]*)</option>

with

<option value="\1">\1</option>

As you're mostly active in the php tag, I assume you're asking for a solution in php. However, let me begin this answer with an advice: If you are looking for a way, state your goal, not a technology you think is suitable. regexps work, but this is far easier in simplexml:

$xml = str_replace("&", "&amp;", $xml); // Fix errors in your XML
$doc = simplexml_load_string($xml);
foreach ($doc->xpath("//option") as $o) {
    $o["value"] = "" . $o;
}
$xml = $doc->asXML();

If you insist on using a regexps, you can do so:

$xml = preg_replace(
    '#<option value="[^"]*">([^<]*)</option>#',
    '<option value="$1">$1</option>', $xml);

Answer 7

A:

I haven't tested this, but I believe this will work, using jQuery.

 $('option').each(function(elm) { $(this).val($(this).text()); });
