Subject: Can't distinguish among ending tags
Consider this HTML code: <p>Line 1.<br>Line 2.<br /></p> My application needs to output the HTML with an RTF layer, preserving as much as possible from the HTML layout/spacing. The problem I'm running into is that HTML::Element doesn't allow me to detect that the <br> tag has no closing tag, the <br /> element is XML-properly empty (bonus points for being able to detect the space before the ending slash), and <p> does have a closing tag. Is there a way to distinguish between these three cases?

<br /> vs. <br> is possible: the former will have an attribute of '/', where the latter will not. However, this only works if the element is self contained. As far as <p> having a closing tag, I'm evaluating how possible that is, but I'm focusing on bug fixes first.

<br> never has a close tag - that is, <br>...</br> is not legal HTML or XHTML. <br /> is not a close tag, it is an empty br element. Note that br elements are always empty!

What I meant is that I'm trying to tell between <br>, <br/> and <br /> because my application must preserve the input HTML as faithfully as possible. It has been suggested above that <br/> will have an attribute of '/', while <br> won't. How can I also get the amount of whitespace in <br /> ?

What you want can't be done using HTML::Parser, which is what HTML::TreeBuilder uses for parsing HTML. You would need to patch HTML::Parser to be able to get the white space information you want. Cheers, Jeff.
