Question

I am trying to get a list of numeric IDs from an XML file. It’s formatted like this.

<Count>Number of things found</Count>
<RetMax>Number of things asked for</RetMax>
<RetStart>0</RetStart>
<IdList>
<Id>ID#</Id>
<Id>ID#</Id>
<Id>ID#</Id>
<Id>ID#</Id>
<Id>ID#</Id>
<Id>ID#</Id>
<Id>ID#</Id>...

The file is generated using Esearch on the pubmed database. Is there a way using php to only get the text that is between the ‘count’,’RetMax’,and’ID’ tags and have it differentiate between them? Preferably in array format.

Answer 1

$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
echo $json->Count;
