What potential issues can arise from having extra spaces before and after significant strings in XML data when processing it with PHP?

Having extra spaces before and after significant strings in XML data can lead to parsing errors when processing the data with PHP. To solve this issue, you can use the trim() function in PHP to remove any leading or trailing spaces from the XML data before parsing it. 

$xmlData = "<data>   Hello, World!   </data>";
$trimmedData = trim($xmlData);
$xml = simplexml_load_string($trimmedData);
