extract substring

[samuelberthelot]

Hi,
I would like to extract 'some string' from the following string:

<A href=\"#\">some string</A>

Attention! This is not an HTML element, it is a STRING, so I can't do
..innerHTML.

'some string' can be of any length.

Can you help ?

thanks

Hard to say as the real problem has not been defined/stated. Answering
the question asked is unlikely to help much.

Hi Samuel,

I would like to extract 'some string' from the following string:

<A href=\"#\">some string</A>

substring and indexOf is your friend:

s = "<A href=\"#\">some string</A>";
start = s.indexOf(">"); // get first '>' index
end = s.lastIndexOf("<"); // get last '<' index
// get whats in between, note that you need to add 1
// to start, becuase it gives the location of the symbol
// which is what we want to skip.
link = s.substring(start + 1, end);
alert(link)

Good luck,
Vincent

If you are simply trying to strip out the HTML tags, then I think:

var s = '<A href=\"#\">some string</A>';
alert( s.replace(/<[^>]*>/g,'') );


Is much simpler. It will strip out *all* tags, so that:

<p>foo <span>bar</span></p>

becomes 'foo bar'.
