passing more then one path to xPath query - php

Question

I have links with a different paths, and trying retrieve data from those links. So I don't want to do it separate. Made a query list, and used foreach on that list.
function passPath($list){
$list = [
"//li[#class='out']/a[1]",
"//ul[#class='ul right_ul clearfix']/li[2]/a",
"//ul[#class='ul right_ul clearfix']/li[2]/a"
];
foreach($list as $val){
return $val;
}
}
Then used that function inside DOMXpath's query.
function getPath($urls){
foreach($urls as $k => $val){
$url = $urls;
$html = content($val);
$path = new \DOMXPath($html);
$xPath = passPath($val);
$route = $path->query($xPath);
foreach($route as $value){
if ($value->nodeValue != false) {
$urls [] = trim($value->getAttribute('href'));
unset($urls[$k]);
}
}
}
return array_unique($urls);
}
it's running without an error. But there is foreach problem here. because it's just retrieving one element's data. not keep going other elements... What I am missing here?
$data = getPath($urls)
var_dump($data)
by the way: content() is file_get_content/loadHTML function.

I changed your code for earning list of href.
# You want to parse all pages using url list. So you created function named `getPath($urls)`.
function getPath($urls) {
# I suggest you'd rather declare $ret for storing values to return.
$ret = [];
# Using foreach, you can parse all url.
foreach ($urls as $k => $url) { # $val is url value of $urls. And I changed $val to $url.
# content() is file_get_content/loadHTML function.
$html = content($url);
# Create new DOMXPath object using $html.
$path = new \DOMXPath($html);
# This function is not required.
# By the way, second element and third element of $xPathList are equal. I think the third element is not required.
// $xPath = passPath($url);
$xPathList = [
"//li[#class='out']/a[1]",
"//ul[#class='ul right_ul clearfix']/li[2]/a",
"//ul[#class='ul right_ul clearfix']/li[2]/a"
];
foreach ($xPathList as $xPath) {
$nodes = $path->query($xPath);
foreach ($nodes as $node) {
if ($node->nodeValue != false) {
$ret[] = trim($node->getAttribute('href'));
}
}
}
}
return array_unique($ret);
}
$data = getPath($urls);
var_dump($data);
