http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22102 XPATH not performing implicit conversion from int to boolean as expected [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |INVALID ------- Additional Comments From [EMAIL PROTECTED] 2003-08-05 16:13 ------- According to XPath1.0, section 2.4 Predicates: [A PredicateExpr is evaluated by evaluating the Expr and converting the result to a boolean. If the result is a number, the result will be converted to true if the number is equal to the context position and will be converted to false otherwise; if the result is not a number, then the result will be converted as if by a call to the boolean function] When "Given that string-length() returns 0 for empty strings", it evaluates record[0] to false, cause the position starts from 1 (as your result). For element "<field>A sample string</field>", record[string-length(normalize-space (field))] = record[15], it evaluates to false too. When Expr is a number, record [string-length(normalize-space(field))] <> record[boolean(string-length (normalize-space(field)))].
