I have a simplexml script which creates a complex object, I just want the information from within the div 'grid' so grab I use xpath to get it.
$id = $sxml->xpath("//*[@id='grid_data']");
This results in big object array which seems to be a mix of objects and arrays and im really struggling to traverse my way through it. The below is a very cut down version. There are 30 members 'Person 1' etc. Each person has a list which contains 25 items and its these I need to access/work on. (["li"]=> array(25))
Ideally I need to loop through each member, and then subsequently loop through each li item, but im getting hung up on using $variable['name'] vs $object->name
Just testing I have tried a variety of ways to get the persons name and I think Im confusing myself trying to wrap my head around objects traversal.
echo $id[0]->div[0][p][a];
echo $id[0]['div'][0]['p']['a'];
echo $id->0->div

Let's use simplexml along with xpath, see comments inline below
<?php
$xml = simplexml_load_file('xml.xml');
// let's take all the divs that have the class "stff_grid"
$divs = $xml->xpath("//*[@class='stff_grid']");
// for each of these elements, let's print out the value inside the first p tag
foreach($divs as $div){
print $div->p->a . PHP_EOL;
// now for each li tag let's print out the contents inside the a tag
foreach ($div->ul->li as $row){
print " - " . $row->a . PHP_EOL;
}
}
/* this outputs the following
Person 1
- 1 hr
- 2 hr
- 3 hr
- 4 hr
- 5 hr
- 6 hr
- 7 hr
- 8 hr
