php - Problem with simpleXML and entity not being defined

Question

I'm trying to parse a XML file, but when loading it simpleXML prints the following warning:

Warning: simplexml_load_file() [function.simplexml-load-file]: gpr_545.xml:55: parser error : Entity 'Oslash' not defined in import.php on line 35

This is that line:

<forenames>B&Oslash;IE</forenames><x> </x>

As it is a warning, I might ignore it, but I'd like to understand what is happening.

Answer 1

HTML-entities like &Oslash is not the same as XML-entities. Here's a table for replacing HTML-entities to XML-entities.

As I can tell from one of your comments to another post, you're having trouble with an entity /. I don't know if this even is a valid HTML-entity, my Firefox won't show the character - only ouputs the entity name. But I found an other table for most entities and their character reference number. Try adding them to your replace-table and you should be safe. /'s reference number is / by the way.
