xmllint

Generally speaking, XML documents are known for being rather large and unwieldy, mostly because of the use of improper developer tools. The parser can come in handy in these situations as the XML needs an initial parsing step to slow down the processing. Since the processing high level protocols in a rather meticulous job, a specialized tool can save you a lot of time, energy and headaches.

xmllint is a tiny console-based application that has the role of emulating the xmllint function in Windows. The idea behind xmllint is to parse one or more XML files, documents that you need to specify when entering the command in the console.

The files allows you to validate the XML doc against Document Type Definitions (DTD) and report on any differences it discovers. According to the developer, the application can help you detect errors both in the code as well as in the XML parser itself. Depending on the options picked, it can also print various types of output.

Unlike any other tools out there, which have a plain role of reading the binary format, the XML parser is less likely to crash during the analysis. At the same time, it is less susceptible to various performance traps, such as buffer copying, for instance.
