The <shipTo> element is not supposed to contain a <price> element embedded within it, but when it does, OrderXMLHandler gets confused and uses the last price it sees This vulnerability sometimes goes by the name

XML injection because, presumably, the attacker has tricked some frontend system into generating an order document without validating the shipping address, thereby allowing the attacker to inject an unexpected XML tag It is not reasonable to expect an XML parser to validate the complete semantics of a document s content However, a parser can do a complete and thorough job of checking the document s structure and, therefore, guarantee to the code that processes the document that the content is at least well-formed A schema definition allows the XML parser to be much more specific about the data types that are allowed to inhabit each tag in the document Validating the XML you receive is not the end of the inputvalidation job, but it is a very good way to start The simplest way to ensure that the order document has the form we expect is to validate it against a DTD The following DTD requires that an order element contain a title, a price, and a shipTo element, and that all those elements are leaf nodes

You can express the same thing in XML Schema as follows:

most of the examples in this book, the following code relies on interfaces introduced in Java 15) This schema requires that all the tags are present and in the right order, but as long as the title, price, and shipTo elements don t have any nested tags, it will accept any values for them After we show how to modify the OrderXMLHandler class to validate against this schema, we come back and tighten up the schema to add stronger validation To enforce that the order XML matches the schema, two things need to change First, the OrderXMLHandler class needs to enable validation Second, it needs to stop processing if validation fails The main() method enables validation by creating a Schema object and registering it with the parser factory Example 102 shows a new main() method for OrderXMLHandler that enables validation The easiest way to cause processing to fail when validation fails is to override the error method, also shown in Example 102 Changes to the original OrderXMLHandler class are in bold
