By defining your own tags, you create the markup language in terms of your specific problem set!
Rather than relying on a generic set of tags which suits everyone's needs adequately, XML allows every person/organization to build their own tag library which suits their needs perfectly.
No validation or well-formedness check will be performed, and template code/structure will be respected to the biggest possible extent in output. In this case, code is expected to be well-formed – no unclosed tags, no unquoted attributes, etc – and the parser will throw exceptions if well-formedness violations are found.
Note that no template mode will allow the use of a special syntax for templates of a non-markup nature.
The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt.
It is unique in that it combines the speed and XML feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known Element Tree API.
Thereafter, you can easily "explore" the tree to get your data.
You can also modify the tree using "add" and "delete" functions and regenerate a formatted XML string from a subtree.
Of course, you can also parse XML data that you have already stored yourself into a memory buffer.Examples of such templates might be text emails or templated documentation.Note that HTML or XML templates can be also processed as template mode will allow the processing of Java Script files in a Thymeleaf application.The first benefit of XML is that because you are writing your own markup language, you are not restricted to a limited set of tags defined by proprietary vendors.Rather than waiting for standards bodies to adopt tag set enhancements (a process which can take quite some time), or for browser companies to adopt each other's standards (yeah right!
