Question

I have a SimpleXML element, from XML like the following:

<Result>
    <BlueAnswer>Blue</BlueAnswer>
    <RedAnswer>Red</RedAnswer>
    <YellowAnswer>Yellow</YellowAnswer>

    <BlueQuestion>What is my favorite color?</BlueQuestion>
    <RedQuestion>What is my favorite color?</RedQuestion>
    <YellowQuestion>What is my favorite color?</YellowQuestion>
</Result>

How do I loop through them with a wildcard, like so:

foreach ($response->Result->wildcard('*Answer') as $answer) {
    echo "Answer: " . $answer;
}

This seems simple, but I can’t seem to figure it out. Thanks for any help in advance.

Answer 1

foreach($response->xpath("/Result/*[substring(name(),string-length(name()) - 5) =  'Answer']") as $answer){
     echo $answer;
}
