No, <x:forEach> is behaving properly. I think you're misunderstanding the mechanism. You're apparently assuming that the scoped variable "addressBook" refers somehow to a tree where the context node is the root element. Instead, the variable refers to the entire parsed tree. Thus, the single "ADDRESS" that's printing corresponds to the single document root element: <addressBook> ... </addressBook>. If you want to loop over each <address> ... </address> element, you'll need to use an expression like $addressBook/addressBook/* This might look odd to you at first, but I'd assert that's just because you used the same name for the scoped variable and the root element of your document. To learn more about the mechanism, instead of printing just "ADDRESS," print a property of the context node (e.g., the tag name). The behavior of <x:forEach> is demonstrated nicely in JSTL's standard-examples application. (*Please* consult it before submitting bug reports.) :-) Thanks! |
I have this code ... <x:forEach select="$addressBook/*"> ADDRESS </x:forEach> ... which produces this output ... ADDRESS ... for this XML file: <addressBook> <address> <firstName>Anna</firstName> <lastName>Keeney</lastName> <email>anna.keeney@worldlink.net</email> <phone type="work">716-873-9644</phone> <phone type="home">716-834-8772</phone> </address> <address> <firstName>Ronald</firstName> <lastName>Dunlap</lastName> <email>ron.dunlap@worldlink.net</email> <phone type="work">716-873-9644</phone> <phone type="home">716-834-8772</phone> </address> </addressBook> The output, as far as I can tell, should be ... ADDRESS ADDRESS ... because there are 2 addresses in the file.
