My next project in the “whittling wood”? Figuring out why XML::RSS::LibXML parses these tags without any problem:
[code language=”xml”] <itunes:category text="News & Politics"/><itunes:image href="http://media.npr.org/images/podcasts/2013/primary/hourly_news_summary-c464279737c989a5fbf3049bc229152af3c36b9d.png?s=1400"/>
[/code]
and produces this internal data structure:
[code language=”perl”] category => bless( {_attributes => [
"text"
],
_content => "",
text => "News & Politics"
}, ‘XML::RSS::LibXML::MagicElement’ ),
image => bless( {
_attributes => [
"href"
],
_content => "",
href => "http://media.npr.org/images/podcasts/2013/primary/hourly_news_summary-c464279737c989a5fbf3049bc229152af3c36b9d.png?s=1400"
}, ‘XML::RSS::LibXML::MagicElement’ ),
[/code]
But then doesn’t have these tags anywhere in the re-rendered XML when it spits it back out again. I know it has to do with the fact that these tags have no content (there’s no opening and closing tag, there’s just the one tag closed with a />), but I don’t know why XML::RSS isn’t properly rendering it when it converts the data structure back to XML.
The easy work-around would be to just do some string matching, recognize these tags in the original XML, copy them and re-insert them into the rendered XML afterwards.
The more difficult fix is to figure out what’s wrong with XML::RSS and try to fix it myself.
Guess which road I’m taking?
