Hpricot strangeness

[D. Krmpotic]

Hi,

Has anyone noticed the following gotcha/bug(?) with empty xml tags in
hpricot: doc = Hpricot("<div><foo/><span>aaaa</span></div>") ;
doc.at("foo") => {elem <foo> {elem <span> "aaaa" </span>}} versus =>
{emptyelem <foo>} for <foo></foo>

How to get around that?

thank you!

I'm not sure I understand the question, but I suspect the XML standard(s)
declare that <foo></foo> is exactly the same as <foo/>, so any XML
implementation has no choice but to treat the contents of foo as NULL or nil.

I just got it - Why has an insect where <foo/> is not recognized as zero-length,
then his infamous Hpricot forgiveness thinks it's supplying a missing <foo>
after the </span>. Report this to his Trac system.

He needs a mode to turn the forgiveness off, to become more useful. Here's a
survey of the differences between Hpricot and REXML:
