Hi all

Im trying to extract just the src url of img tag from a page.

my preg_match_all is

preg_match_all('/(src)="(.*?)"/i',$f, $m);

BUT its returning

an array with 3 types of match :

1 - with src= IE src="graphics/homeandawaybanner.jpg"

2 - only the tx src IE src

&
( what i actually want )

the url IE graphics/homeandawaybanner.jpg

How do i adjust my preg to only extarct the url from src

Hope someone can help with this


Cheers

If the third element of the array is what you are looking for, can't you just take that value from the array?

PHP Code:

preg_match_all('/(src)="(.*?)"/i',$f, $m);

$src = $m[2]; 


No its actually creating 27 elements in 1 array representing 9 images on the page i am scraping

first 9 are in format src="url"
second 9 ar just src
and the third 9 are the urls i require.

sorry my fault. I was mis interpreting the array.
Thanks. Your absolutely correct in the solution you offered.

Cheers

Edit
In that case disregard this.

Try:

PHP Code:

preg_match_all('/(src)="(.*?)"/i',$f, $m, PREG_SET_ORDER); 


Using the above the third element of the array should contain an array of URLs.

Yur thats the preg had started to use. I have just realized that it actually returns everything with a src attr which isnt actually as want

so
have amended to be

preg_match_all('/(<img src)="(.*?)"/i',$f, $m);

which appears to be working

Cheers

If you're only interested in the url, I do believe you can also skip the parentheses around <img src.
Right now your regexp will match three things:

1) The complete matched string, <img src="some_url"
2) The first parentheses, <img src
3) The second parentheses, some_url

And from my understanding you don't need 2).

Edit:
Also, I think the questionmark inside the seccond parentheses is unnecessary. The * already matches zero or more.

I don't recommend using regexs at all if you're trying to parse content out of an html file. Using a DOM parser can be much quicker and less error prone.

That looks really handy, Null! I didn't know about that, I guess I should read more PHP.net Thanks for posting that link

have you tried with htmlsimple dom , simplehtmldom[dot]sourceforge[dot]net/manual.htm

it is good too.
