Get a concrete part of a string

Recommended Posts

edgariyu

Hi to everyone! I'm new with Autoit, so i hope you could help me starting with this language. Here comes my questions:

Let's put the example of these 3 strings:

http://www.ejemplo1.com

http://www.ejemplo2.es/loquesea/xx.html

http://www.problema.solucion.net/loquesea/xdew2/de.html

¿There's any way to get the extension of the direccion? I mean, in the first case will be com, in the second es and in the last net.

My other question is if it's possible to count the number of times that a character is repeated in a string, for example, count the number of times that the character & is repeated in this string: http://www.ejemplo.com/dsdsada&dsadasda&sds%ddfsd&a

Thaks to all for your help!!

edgariyu,

Welcome to the AutoIt forum. :idea:

Your first question can be solved like this: :)

$sText = "http://www.ejemplo1.com"

$sExt = StringRegExpReplace($sText, "^.*\.", "")

MsgBox(0, "Ext", "The extension is: " & $sExt

And the the second like this: :(

$sText = "http://www.ejemplo.com/dsdsada&dsadasda&sds%ddfsd&a"

StringRegExpReplace($sText, "&", "&")

MsgBox(0, "Ext", "The number of '&'s: " & @extended)

I hope that helps. :)

Thaks Melba23 for your fast answer!! That was exactly what i was looking for!

The only thing that i don't understand at all is in the first piece of code, if you put www.ejemplo1.com/somethingelse/dsdasd , the code take all that goes after the last point (com/smethingelse/...). How could i erase that part? or if you have www.example.other.net/semething and you want to take the "other".

I don't understand the patern ^.*\. :s

Thaks for your help!!!

As much as I have a love-hate relationship with RegEx, using it to answer the second question is perhaps over the top, although it won't really make a lot of difference. The onlt reason I mention it is becuase it may be a bit too soon in the OPs experience with AutoIt to start trying to figure out SREs. Not too mention I forgot to pick on M23 yesterday so I have to catch up today.

$sText = "http://www.ejemplo.com/dsdsada&dsadasda&sds%ddfsd&a"

StringReplace($sText, "&", "&")
$sVal = @Extended
MsgBox(0, "Ext", "The number of '&'s: " & $sVal)
MsgBox(0, "Result", "The number of repetitions is ", $sVal-1)

edgariyu,

George will no doubt be along in a minute with a fancy SRE, but this will do just as well: :)

$sText = " www.ejemplo1.com/somethingelse/dsdasd "

$aArray = StringSplit(StringRegExpReplace($sText, "^.*\.", ""), "/")

MsgBox(0, "Ext", "The extension is: " & $aArray[1])

Edit: I see he beat me too it - but did not leave an SRE. Must be an off day...... :idea:

edgariyu - we are not always like this, but we do try and have fun if we can. :(

I was waiting for someone whom I shall leave un-named to check his PM's so he could check the expression himself.

Beyond the excellent answer already provided, let me ask a question:

In the case of httm://www.asus.com.tw/index.html what are you expecting: com or tw or com.tw?

There are increasingly more and more subdomains in use and this may affect your script(s).

Good question! I expected to get com.tw, and the fact that the URL ends with a .html is a problem too. I solved triming the string when it's necessary, but i don't know how to get the com.tw :s

Separating the domain and the path/file parts is not the problem.

The issue is more with the trend towards domain names that have more than the historic 3 components. Not only there is an explosion of TLD (top level domains) but the (now independant) national CANNs have a number of "features", well beyond simple vanity. For instance you might encouter www.abcd.domain.com.oz.au and a large number of weird (non-existant or phasing out) country "codes" (.su, .dd, .ac, ...).

The advent of IDN is now making identifying TLDs really more difficult, anyway, more than what a single regexp can (reasonably) do. Given that the vast majority of potential web users will find it easier to have urls written in their own (non-latin) scripts, I bet we will see more and more of these unusual domain names.

Beside using some tables lookups, I don't see any one liner here.

I'm new with regular expresions and it's being kind of hard :s

Can anyone tell me how can i get the text between the points text1.whatiwant.text2 for use it in a StringRegExpReplace?

I don't know how to tell the pattern to get the text between the twoo points, because using .*\. and replacing it for "" then i get "text2", and with \..* i get the other text1 :s

On purpose, can anyone tell me a page or manual to learn more about regular expresions? (besides of the one of help file )

Thanks for your help !!

PCRE: follow the link in the help page. This is the definitive PCRE reference. No tutorial, just reference.

tools: RexEx Coach is very good and freeware, RegExp Buddy is payware and excellent (albeit PCRE support is years behind) other good tools floating in this forum (sticking to PCRE as implemented by AutoIt). Google and forum search are your friends.

Now to extract the part you want:

$res = StringRegExpReplace($s, "[^.]*?\.([^.]*?)\..*", "$1")

should do it.

This is still in Beta but you might want to give it a try for testing and experimenting with PCRE expressions.
