javascript - counting the number of nodes is not working -


i have xml file :

<?xml version="1.0" encoding="iso-8859-1"?> <food> <cuisine type="chinese"> <restaurant name = "panda express"> <location id= "0"></location> <phone id = "1"></phone> <city id="2"></phone> </restaurant> <restaurant name = "mr. chau's"> </restaurant> </cuisine> <cuisine type="indian"> <restaurant name = "shan"> </restaurant> </cuisine> </food>

and trying count number of cuisine nodes code have, know right when try print out length of nodelist says it's 0

//starts talking xml document if(window.xmlhttprequest){ xmlhttp = new xmlhttprequest(); }else{ xmlhttp = new activexobject("microsoft.xmlhttp"); } xmlhttp.open("get","data.xml", false); xmlhttp.send(); xmldata = xmlhttp.responsexml; //fills first combobox var sel = document.getelementbyid('cuisinelist'); cuisinelist = xmldata.getelementsbytagname('cuisine'); document.getelementbyid("test").innerhtml = cuisinelist.length;

two possible answers:

a) xml has error, have </phone> need </city>. you'll need fix that. :-) (but i'm guessing that's in question, not in real data, because if in real data wouldn't getting 0, wouldn't think; you'd getting error.)

b) check response headers, may server isn't returning xml correct mime type. if not:

  1. the best answer correct server configuration serves xml files correctly.

  2. if whatever reason can't that, can use overridemimetype force xmlhttprequest treat response xml:

    xmlhttp.open("get","data.xml", false); xmlhttp.overridemimetype("text/xml"); // <=== new bit xmlhttp.send(); xmldata = xmlhttp.responsexml;

if fix those, works: live working copy | source

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
