Hi all,
I've been trying unsuccessfully to get the text from html page. Html
tag that I'm interested in looks like this:
<a class=link
href="http://www.something.c om/_something.php? type=cart">Shop ping
Cart</a>
<div><em class=newentry> <a href=http://nothing.com>New
Age</a></em></div>
>From the above tag, I want to extract "Shopping Cart". I'm not very
good with RE. I tried this:
$lines = file_get_conten ts("http://theabovetag.com/page.html");
preg_match_all( "/(<a\ class\=link\ href\=(.*)>)(<\/a>)/", $lines,
$matches1);
The above RE gives me "Shopping Cart" plus "New Age" as well. I just
want "Shopping Cart". What am I doing wrong? My RE is somehow ignoring
</atag right after Shopping Cart and instead accepting </aafter New
Age. Please help! 3  3316  cr*********@yah oo.com wrote:

It most likely has to do with the greediness of *. Regular expressions
will match the *longest* possible string. To prevent this, use '?'.
given the string: "<a>text</a>more</a>"
<a>.*</amatches "<a>text</a>more</a>"
<a>.*?</amatches "<a>text</a>"

Well what i basically want is:
<a class="somethin g" href=http://something.com/abc.php">Shoppi ng
Cart</a>
I want the RE to parse the HTML tag and see if it starts with '<a
class="somethin g" href=', then IGNORE whatever is between 'href=' and
'>', and ending with '</a>'. I couldn't figure out how to "ignore" the
text in between. cr*********@yah oo.com wrote:

Instead of a (greedy) * operator, use a negation class that parses
everything upto an certain character :
/(<a\ class\=link\ href\=([^>]*)>)([^<]*)(<\/a>)/ This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi
I have used some of this code from the PHP manual, but I am bloody hopeless
with regular expressions.
Was hoping somebody could offer a hand.
The output of this will put the name of a form field beside name.
I want to get the following but not sure how to modify the code below.
1. Field Name (to appear beside NAME:)
2. Field Type (to appear beside TYPE:)

Hi,
i'm using the regular expression \b\w to find the beginning of a word,
in my C# application. If the word is 'public', for example, it works.
However, if the word is '<public', it does not work: it seems that <
is not a valid character, so the beginning of the word starts at
theletter 'p' instead of '<'.
Because I'm not an expert in regular expressions, maybe someone of you

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in
matches. I would like to get what the actual regular expression is.
In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION
DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH
CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How
do I gain access to the expression (not the matches) at runtime?
Thanks,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
