I'm currently working on the XML::LibXML plugin for the Template Toolkit
atm. It has two interfaces. The first, more complicated interface,
allows you to pass named parameters for the type of data source you want
parsed. The second tries to guess what you meant when you passed in a
single scalar.
Here's the current code for that guessing:
sub _guess_type
{
# look for a filehandle
return "fh" if _openhandle($_[0]);
# okay, look for the xml declaration at the start
return "string" if $_[0] =~ m/^\<\?xml/;
# okay, look for the html declaration anywhere in the doc
return "html_string" if $_[0] =~ m/<html> /i;
# okay, does this contain a "<" symbol, and declare it to be
# xml if it's got one, though they should use "<?xml"
return "string" if $_[0] =~ m{\<};
# okay, we've tried everything else, return a filename
return "file";
}
That'll be turned into a call to $libxml-> parse_$returnvalue($data)
later on.
My question is then, is the separate html detection stage needed, or if I
throw it all at parse_html_string? It all seems to work atm, but I was
wondering if I'm jumping though the wrong hoops.
Mark.
