I need to create regular expression for:

<span class="myClass">some text 1</span>
some text under 1
<span class="myClass">some text 2</span>
some text under 2
<span class="myClass">some text 3</span>
some text under 3

How i can get into array all text 

some text n

and

 some text under n

using preg_match_all

class of span is knowing

tnx

 

Based on your sample:

Raw Match Pattern:
<span class="myClass">(.*?)</span>\r\n(.*?)(?:\r|$)

PHP Code Example:
<?php
$sourcestring="your source string";
preg_match_all('#<span class="myClass">(.*?)</span>\r\n(.*?)(?:\r|$)#',$sourcestring,$matches);
echo "<pre>".print_r($matches,true);
?>

$matches Array:
(
    [0] => Array
        (
            [0] => <span class="myClass">some text 1</span>
some text under 1
            [1] => <span class="myClass">some text 2</span>
some text under 2
            [2] => <span class="myClass">some text 3</span>
some text under 3
        )

    [1] => Array
        (
            [0] => some text 1
            [1] => some text 2
            [2] => some text 3
        )

    [2] => Array
        (
            [0] => some text under 1
            [1] => some text under 2
            [2] => some text under 3
        )

)

Soory, but it isn`t work if:

1. \r\n not exists in text

2. if  another HTML tags exists in  "some text under n"

 

<span class="xpert">some text 1. </span></p><p>some text under 1<br><span class="xpert">....

it may looks like this :( 

If you require a working solution for your actual text then we need to see your actual text.
