Question

Im using PEAR XML Serializer to generate xml results from array inputs. I found out that empty array elements are encoded like this: <arraykey/>. I d rather prefer it this way <arraykey></arraykey>

Below are my options:

            $options = array
            (
                 indent  =>      ,
                 defaultTagName  => $this->xml_tag_name,
                 addDecl  => true,
                 encoding   =>  UTF-8 ,
                 rootName  => $this->xml_root_name,
                XML_SERIALIZER_OPTION_RETURN_RESULT => true
            );

Are there any other options to add to fix this?

Answer 1

In the actual state of the library no, it uses PEAR XML_Util and if you look at the code of XML_Util::createTagFromArray(), it does the following for empty tags:

if (!isset($tag[ content ]) || (string)$tag[ content ] ==   )
{
    $tag = sprintf( <%s%s /> , $tag[ qname ], $attList);
}

You could probably fake empty content with a string that contains a space such as but that would result into something like <arraykey> </arraykey>.

BTW, <arraykey/> is totally legal in XML (it s recommended for empty tags, it s also used in XHTML).

Answer 2

Is there a concrete reason you prefer the <tag></tag> format over <tag />? Noting that (as another poster said) <tag /> is totally valid XML. Personally I prefer self-closing for an empty tag.
