[SOLVED] Anyone able to help on regex issue with my html source code...

[jkrystof]

If anyone can help out with preg_match_all or some guidance that would be greatly appreciated. I'm trying to pull some user info from my html which looks like below.

 

<div class="td user_ref">
<p class="alignright" id="user">
	<span class="Height">FT</span>
	<span><span class="user_ref" userid="jbk" mwformat=",2" userfield="height1">6.3</span>
	</span>
</p>
</div>

 

I am looking to pull only the 6.3 and place it into an array. I've displayed one div class but I will have between 20 to 30 html segments just like this in my complete html. Also, there are other div classes not equal to "td user_ref" within the html which should be ignored. I would like to extract each height and place it within the height array.

 

preg_match_all($string_pattern, $html, $height);

 

I've been attempting to learn the $string_pattern part with regular expressions but only getting constant headaches.

 

all help and thoughts appreciated..thanks

Assumes userfield="height1" is a unique attribute to the span inside the div you want to match, that will be in all the spans inside those divs.

preg_match_all('~<div.+?"td user_ref"[^>]*>.+?<span.+?userfield="height1"[^>]*>(.*?)</span>~is',$html,$height);
print_r($height[1]);

Thanks, that worked for me. There was one issue I was still having on another segment within the html where I'm using regex too.

 

<div class="td user_ref">
   <p class="mweight" id="user_id"> Weight Value </p>
</div>

 

In this case I used the following regex and I don't know what to put in following the id=??????? because my user id is a numeric value greater than 1, i.e id="user1", "user2"..."user27".."user98" etc. Also I don't want to include the class="mweight" because that is the same in other <p></p> segments I'm not interested in.

 

I can return the first 9 if I use a /d but I don't know how to return for all numbers greater than or equal to 1.

 

 

preg_match_all('~<div.+?"td user_ref"[^>]*>.+?<p.+?id=???????[^>]*>(.*?)</p>~is',$html,$weight);

 

thanks for your help

id="\d+?"

[jkrystof]

thanks, it does work but for some rreason I only get every other user_id entry saved to my $weight array. any thoughts why this would happen?

 

for example,

$weight[0]= "user2"

$weight[1]= "user4"

etc...

 

I'm using the following code

 

preg_match_all('~<div.+?"td user_ref"[^>]*>.+?<p.+?id="user\d+?"[^>]*>(.*?)</p>~is',$html,$weight);

 

the html is the same for each user,

 

<div class="td user_ref">
   <p class="mweight" id="user_id"> Weight Value </p>
</div>

try adding

 

.*?</div>

 

to the end of your pattern.

[jkrystof]

gave it a try but still same result. I'll have to take a deeper look at it later today when I have a bit of time. seems odd to me. thanks

[.josh]

okay then can you give an example of the whole page that you're trying to pull the info from?

[jkrystof]

thanks crayon for your help. i played with it some this morning and got it to work now. im not exactly sure why it was skipping every other one but the following worked for me.

 

preg_match_all('~<div.+?class="td.+?"[^>]*>.+?<p.+?id=".+?height.+?"[^>]*>(.*?)</p>~is',$target2,$height);
