RE: [PHP] Text between two tags
try explode using td align=right class=yfnc_tabledata1 then on array index[1] explode /td your answer will then be in index[0] Hope this helps Mike Message Received: Nov 10 2005, 03:01 PM From: Normmy2k [EMAIL PROTECTED] To: php-general@lists.php.net Cc: Subject: [PHP] Text between two tags Hello I'm trying to extract some text between two tags: Example I have this string : $text='td/td td align=right class=yfnc_tabledata3/td td/td td align=right class=yfnc_tabledata2/td td/td td align=right class=yfnc_tabledata11234/td td/td td/td td/td td align=right class=yfnc_tabledata5/td '; And I want to retrieve the number 1234 between td align=right class=yfnc_tabledata1 and /td Any idea??

Re: [PHP] Text between two tags
HI, Hello I'm trying to extract some text between two tags: I am answering your question from the perspective that you are going to have more than one column that you want the data from. I would use this pattern and this code to test the pattern. ? $pattern=/(td align=\(.*)\ class=\(.*)\(.*)\/td)/; $text='td/td td align=right class=yfnc_tabledata3/td td/td td align=right class=yfnc_tabledata2/td td/td td align=right class=yfnc_tabledata11234/td td/td td/td td/td td align=right class=yfnc_tabledata5/td '; preg_match_all($pattern, $text, $matches); print_r($matches); ? This will give you: [0] = Array ( [0] = td align=right class=yfnc_tabledata3/td [1] = td align=right class=yfnc_tabledata2/td [2] = td align=right class=yfnc_tabledata11234/td ) [1] = Array ( [0] = td align=right class=yfnc_tabledata3/td [1] = td align=right class=yfnc_tabledata2/td [2] = td align=right class=yfnc_tabledata11234/td ) [2] = Array ( [0] = right [1] = right [2] = right ) [3] = Array ( [0] = yfnc_tabledata3 [1] = yfnc_tabledata2 [2] = yfnc_tabledata1 ) [4] = Array ( [0] = [1] = [2] = 1234 ) THen you can loop through $matches[4] and you will get all of the values in your row. $mathces[3] will give you your class names and $matches[2] will give you the alignment and $matches[1] will give you the whole td blah blah blah /td string. You could explode on tr and get each new row of your table in a new element in an array and repeat the process for your entire table. Do note that my regular expression will only return columns with a class name and align attribute. You can use $matches[0] elements if you are needing to replace what is there with other information. I hope this helps. Please let me know if it does what you are asking for as I am in need of good regular expression practice.

Re: [PHP] Text between two tags
Maybe just treat it like XML and use PHP's XML parsing routines. Should work
pretty good but maybe someone else has a better way of handling it. (code below)
-TG
// $string - contains your HTML string
$innerText = ;
$_XML_PARSER = xml_parser_create();
xml_set_element_handler($_XML_PARSER,'xml_open_element_function','xml_close_element_function');
xml_set_character_data_handler($_XML_PARSER,'xml_handle_character_data');
xml_parse($_XML_PARSER,$string,strlen($string));
xml_parser_free($_XML_PARSER);
echo $innerText;
function xml_response_open_element_function($p, $element, $attributes){
global $grabInnerText;
if (strtolower($element) == td AND $attributes['class'] ==
yfnc_tabledata1) {
$grabInnerText = true;
} else {
$grabInnerText = false;
}
}
function xml_response_close_element_function($p, $element){
global $grabInnerText;
// Probably unnecessary?
$grabInnerText = false;
}
function xml_response_handle_character_data_pdf($p, $cdata){
global $grabInnerText;
global $innerText;
if ($grabInnerText) {
$innerText .= $cdata;
}
}

Hello
I'm trying to extract some text between two tags:
Example
I have this string :
$text='td/td
td align=right class=yfnc_tabledata3/td
td/td
td align=right class=yfnc_tabledata2/td
td/td
td align=right class=yfnc_tabledata11234/td
td/td td/td td/td td align=right class=yfnc_tabledata5/td ';
And I want to retrieve the number 1234 between td align=right
class=yfnc_tabledata1 and /td
Any idea??
Normmy.

Re: [PHP] Text between two tags
Great example.. haha.. I knew someone would pull some nice regex out for this one.. I suck at regex. hah I still like my XML parsing fix, but Leonard's regex is probably better. hah -TG = = = Original message = = = HI, Hello I'm trying to extract some text between two tags: I am answering your question from the perspective that you are going to have more than one column that you want the data from.
