RegEx.. Finding pattern?

[Pheddy]

Hi All!
I'm a little confused by using RegExe in general.
Does anybody know how the pattern would look like if I needed to print out anything in between two known blocks?

The code looks like this:

<span class=bld>2832.1600 USD</span>

I would need to extract the number 2832.1600

Thanks!

Well in general for testing I'd recommend Rubular.com or a Regex Testing tool from Rad Software http://www.radsoftware.com.au/regexdesigner/

extract the number which can be done in many way depending on what exactly you are trying to parse.

See Rubular link for your particular example

The pattern is
^<span.*?>(\d*\ .\d*).*<\/span>$

Now the explanation
From the start of the line (^ character)
You need to have "<span" characters
Followed by some other characters until the ">" character (it is done by using .*? non greedy technique which takes character after character (?) and sees if it matches)
Now you'll have 0 or more digits followed by a point and than followed by 0 or more digits (\d*\.\d* - it is also saved with the parenthesis)
Followed by 0 or more characters (.*)
Until "</span>" characters
And the line should end here ($ character)

Couldn't make any matches with

^<span.*?>(\d*\.\d*).*<\/span>$

Please note I use VBScript version 5.8

OH I found the problem.. The think Is it is loaded from a HTML source and theres more characters on the entire line wich looks like this:

<div id=currency_converter_result>320 GBP = <span class=bld>2816.6400 DKK</span>
