What is MSXML?
MSXML stands for Microsoft XML and this refers to a set of core services developed by Microsoft Corporation to allow VBScript, JScript, and Microsoft development applications to create other apps that are based on XML. XML or Extensible Markup Language is the main tool used in the internet for encoding documents. It has also become the default format for various office-related applications and programs like MS Office and Open Office.
The best feature of MSXML is that it allows wide interoperability between a variety of applications that are based or compatible with the XML standard. With its core services, MSXML’s DOM or Document Object Model became the standard library for API’s or application programming interfaces. This is especially helpful when one tries to access documents created in XML. It also features support for XML digital signatures wherein data is protected through an encryption technology. It can also be used to verify the authenticity of the data involved. For those who would like to find programming alternatives to the Document Object Model, MSXML also has SAX or Simple API for XML. Aside from this, accessing XML Schema documents can also be done through SOM or Schema Object Model.
MSXML started with the version 4.0 of Microsoft Internet Explorer. With the initial version, basic processing and parsing of XML documents were involved. Over the years, MSXML was released with newer and updated features that included a much safer HTTP access point and complete implementation of XSLT and XPath based on W3C specifications and standards. By 2001, MSXML version 4.0 was released and this now became the Microsoft XML Core Services. This particular version even made further improvements on HTTP data access and supports XSD Schema types. MSXML 4.0 was also the start of DOM-SAX integration. Other versions of MSXML include MSXML 5.0 and MSXML 6.0. The 5.0 version was designed specifically for Microsoft’s office-based application, MS Office. This version comes pre-installed on Office 2003 and 2007 versions. MSXML 6.0 meanwhile is the latest version and comes along with MS SQL Server 2005, Windows XP SP3, Windows Vista, and Windows 7.
