Hi all,

I am new in learning regular expressions and I need a little bit help.

 

How do I match input type elements from a site.

I need to match all and in case that type of input is text (type="text"), I have to check if value attribute exists .

The type could be in every possible position in the element such as <input type="text" value="Login" ...> or <InPut value="Password" type="text" ...> 

 If exists input element and every input element have value print --> OK

In other case , print --> input element does not have value attribue 

else print --> I did;t find input element.

 

And something finally, I would like to check also textareas.

The different is that I have to check if text exists between <textarea ...> and </textarea>

This regex will matche an input tag containing 'type="text"':

(?i)<input[^>]*type="text"[^>]*>

Not sure what you mean by "if text exists", but you can probably use the regex I posted to solve this.

I need to check also if exists value attribute in this input element.

Could you help me ?

I mean that :

case 1 <textarea cols="2" row="2">Hello</textarea>

case 2 <textarea cols="2" row="2">&nbsp;</textarea>

case 3 <textarea cols="2" row="2"></textarea>

 

Case 1 is right use , while case 2 and 3 are wrong.  

Somebody ??

I don't like helping people who are impatient.

Good luck.

as you wish

As I advise most, you are most likely better served using the HTML DOM to parse HTML, rather than a regex.  It is very easy create vaild HTML that will break a given regex patten.
