Converting RSS feed to json is missing pieces-CodePudding

I am trying to convert a RSS feed to json PHP. I get the title, description etc. but I am missing all elements starting with "itunes".

This is for instance not showing in my json:

<itunes:subtitle>Subtitle text here</itunes:subtitle>

But these are showing:

<title>Title here</title>
<description>Description here</description>

I think it has something to do with converting the XML to json, which I use this code for:

function Parse($url) {
    $fileContents= file_get_contents($url);
    $fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);
    $fileContents = trim(str_replace('"', "'", $fileContents));
    $simpleXml = simplexml_load_string($fileContents);
    $json = json_encode($simpleXml);
    return $json;
}

Can anybody help me understand where the error occurs?

CodePudding user response：

Ahh you are destroying the XML with the string replacement you are doing. Instead all you need to do is convert the tags with : in them to something that will be valid in PHP once converted to JSON

So just do the str_replace() to convert

<itunes:subtitle>Subtitle text here</itunes:subtitle>

<itunes_subtitle>Subtitle text here</itunes_subtitle>

That will make those tags legal when converted to a PHP data structure

function Parse($url) {
    $fileContents= file_get_contents($url);
    
    $fileContents = str_replace(':', '_', $fileContents);
    
    $simpleXml = simplexml_load_string($fileContents);
    $json = json_encode($simpleXml);
    return $json;
}
