how return more 1 node on page? here code using, returns 1st node found. $dom = new domdocument; $dom->loadhtmlfile($url); $xpath = new domxpath($dom); $users= $xpath->query('//b[@class="xc_user"]'); echo $users->item(0)->nodevalue; $users domnodelist, can iterate over: foreach($users $node) { echo $node->nodevalue; }

to replace multiple words, i'm using looping thru candidates, , replacing 1 one. there better way? create or replace function "myreplace"(text, _varchar, _varchar) returns "pg_catalog"."text" $body$ declare int; result text; begin result = $1; in 1 .. array_length( $2, 1 ) loop result = replace( result, $2[ ], $3[ ] ); end loop; return result; end $body$ language 'plpgsql'; besides making stable , strict, , switching using pl/perl or c, there isn't optimization can make faster.

i have requirement have pass values next page via querystring. querystring coming third party , need have on otherpage analysis. i response.redirect , add querystring recieve them other page. problem .net environment encoding/encrypting of special characters used them dont want not bring correct values in new page. example: passed url : abcd.efgh=testing|value1=rtedf%20value2%202010-04-07%207pm|value3=aaaa this gets changed abcd.efgh=testing|value1%3drtedf+value2+2010-04-07+7pm|value3%3daaaa it looks "=" becomes "%3d" , "%20" space becomes "+" how can stop encoding of url , pass in original form. your querystrings being url encoded . standard behaviour due how urls should formatted. need on receiving page use urldecode in order original string.
