Hi, Can you give this a try?
e = REXML::Document.new(ie.text).root.elements e["/tokens/ShortUrl[starts-with(@url, "resetpassword.aspx?m=7fb83717-9606-4022-bd4e-67b6f6582ada"].attributes["url"] As you already know value of 'm' in query string you can create a string a give it a try. - Angrez On 5/11/07, Zeljko <[EMAIL PROTECTED]> wrote:
I have xml that looks like this. <tokens> <ShortUrl url="resetpassword.aspx?m=7fb83717-9606-4022-bd4e-67b6f6582ada&code=2271ad0e-d627-4e6c-bdfb-2b11d354e9ac" hash="BF8E8F60E722E92C7ED8303916591AB4" /> </tokens> I need to get value of "hash" attribute (BF8E8F60E722E92C7ED8303916591AB4). I know the value of "m" url parameter (inside "url" attribute) (7fb83717-9606-4022-bd4e-67b6f6582ada), but I do not know the value of "code" url parameter. I know how to get attribute of a tag when I know another attribute of that tag. For example, if I knew "hash" attribute and needed "url" attribute, I would do it like this: e = REXML::Document.new (ie.text).root.elements e["/tokens/[EMAIL PROTECTED]'BF8E8F60E722E92C7ED8303916591AB4']"].attributes["url"] => "resetpassword.aspx?m=7fb83717-9606-4022-bd4e-67b6f6582ada&code=2271ad0e-d627-4e6c-bdfb-2b11d354e9ac" But, I know only part of "url" attribute. Of course, this does not work (because e[...] returns nil). e["/tokens/[EMAIL PROTECTED]'resetpassword.aspx?m=7fb83717-9606-4022-bd4e-67b6f6582ada&code=']"].attributes["hash"] => NoMethodError: undefined method `attributes' for nil:NilClass I have heard that there are xpath string functions (http://www.w3.org/TR/xpath#section-String-Functions ), but I did not understand how to use them, or would it even help in this case. I have solved this problem with regular expressions, but I guess there must be xpath solution. Also, I have already asked my developer to simplify that xml, so I can use it, but that has low priority because I have already solved the problem. Does anybody know how to do this using xpath?
