I have a xml file and i need to select grandchild or grandchild's child using xpath.
Here is xml file link - XML file I do that with this code:
<?php
$dom = new DOMDocument();
$dom->validateOnParse = TRUE;
$dom->load('file.xml')
$xpath = new DomXPath($dom);
$nodes = $xpath->query('//question[@id = "1"]/answer[@id = "1"]/subquestion[@id = "1-1"]/answer[@id = "1-1"]');
?>
Above code work fine but i need shorten query as i don't know the dept of subquestions.
Thanks
You can use the // at any point in the query, so
//question[@id = "1"]//subquestion[@id = "1-1"]/answer[@id = "1-1"]
can find it at any level below the one your after.
You can always play with these things in something like https://www.freeformatter.com/xpath-tester.html which allows you to test your expressions.
