Re: [xsl] Need an XPath 2.0 expression that identifies a lon

Well, a predicate using name()='p' is bad news because it depends on namespace
prefixes, which are arbitrary. Use self::p, assuming it's a no-namespace
element, or self::xhtml:p if its in the XHTML namespace.

You could also do something like

> //p[o:p eq '&#160;'][every $p in following-sibling::*[position() le 10]
satisfies $p[self::p/o:p eq '&#160;']]
