NOTE: I have the atoi just to validate that the scanf validation works. scanf ( "%[0987654321.-]s" , buf ); i = atoi ( buf ); if ( i ) index = i ; 回答1: Using scanf() is usually a bad idea for user input since failure leaves the FILE pointer at an unknown position. That's because scanf stands for "scan formatted" and there is little more unformatted than user input. I would suggest using fgets() to get a line in, followed by

Alternative you can use the regex based test as: if(preg_match('/^\d+$/',$_GET['id'])) { // valid input. } else { // invalid input. } 回答2: Can use $validatedValue = filter_input(INPUT_GET, 'id', FILTER_VALIDATE_INT

I would like to parse a Schema doc using JAXB. 回答1: Of course. Most of the time you can just point your browser to the URL that serves as the namespace for the XML document. This also works with XML Schema: http://www.w3.org/2001/XMLSchema The XSD is linked from there. 回答2: Also check XSOM . This is what JAXB RI uses to load and process XSDs. 回答3: There are two versions of the XML Schema Definition

How can I validate those HTML pages and get a log telling me what errors/warnings on what pages? Then I can fix the errors manually. I have tried JTidyFilter, but that doesn't work for me. 回答1: You can use the W3C validator directly from Java, see w3c-jabi . 回答2: There is also an experimental API available from W3C to help automate validation. They kindly ask that you throttle requests, and also offer
