In contrast, St AX is a “streaming” API like SAX with minimal memory footprint regardless of data size, but its “pull” model is nearly as easy to use and understand as DOM – and St AX also features a writer.

You could of course run a reformatter on the generated file but that might add a lot of processing time for large files. This article focuses on how one can parse a XML file in Java. That’s why, the design goals of XML emphasize simplicity, generality, and usability across the Internet. Implementation Idea of How St AX parser works : Image Source : Input File : This is sample input file made by the author as an example to show how St AX parser is used . XML database files usually are large and contains many tags nested within each other . It was designed to be both human- and machine-readable. Create Test Xml Schema Validation class as shown below: Use XMLStream Reader2.validate Against() method to validate the XML document against the XML schema (see line 29 below). Note that it is in accordance with described above as it defines the ‘title’ element (see line 4 below) instead of ‘salary’ element.That said, it does have a few drawbacks, such as lack of pretty printing and schema validation. One disadvantage of the St AX writer is its lack of support for “pretty printing,” i.e.

formatting XML with line breaks and perhaps indentation.

Then try to validate invalid (see line 46 below)and verify that the validation fails .

The output of the program demonstrating both validation success and failure scenarios is shown below.

Interface XMLStream Reader provides PULL API (compared to SAX which provides PUSH API).
