Re: Error in XPath expression with IE

I'm sorry for not be explicit enough, my fault. The lack of the / was
a copy&paste problem, it should be there.

The [1] was a not-well-done example, cause in reality that is a variable,

xmlDoc.selectNodes("(//Menu)["+pos+"]/parent::Menu/MenuTitulo");

I'm very sorry for being so lazy and thanks a lot.

That isn't correct Xpath so will generate an error on any conformant
XPath system (I don't know if it would work in wd-xsl, but I didn't
think that had that axis at all)


adding a / so it says:

  (//Menu)[1]/ancestor-or-self::Menu/MenuTitulo

would make it syntactically correct but still strange.

 (//Menu)[1]

will select a Menu node (or nothing) so ancestor-or-self::Menu will
always be the same as self::Menu so it can be omitted, so the expression
is then equivalent to

  (//Menu)[1]/MenuTitulo
