Validating the xml
In this page you can check the validity of your XML Schema (XSD) file. The library used in this page is jaxp, Java API for XML Processing, version 1.4, from Java(TM) SE Runtime Environment (build 1.7.0_06-b24).by Domenico Briganti is licensed under a Creative Commons Attribuzione 3.0 Unported License.XML validation is the process of checking a document written in XML (e Xtensible Markup Language) to confirm that it is both well-formed and also "valid" in that it follows a defined structure.A well-formed document follows the basic syntactic rules of XML, which are the same for all XML documents.
All three provide identical APIs in lxml, represented by validator classes with the obvious names.
The reason is that XML software should be small, fast, and compatible.
HTML browsers are allowed to display HTML documents with errors (like missing end tags). A "well formed" XML document is not the same as a "valid" XML document. In addition, it must conform to a document type definition.
lxml also provides support for ISO-Schematron, based on the pure-XSLT skeleton implementation of Schematron: There is also basic support for The parser in lxml can do on-the-fly validation of a document against a DTD or an XML schema.
The DTD is retrieved automatically based on the DOCTYPE of the parsed document.
If you want to validate an XML document against a DTD that is not referenced by the document itself, you can use the keyword argument to parse from a file.
