XML Development Tools

XML is an open framework for data exchange and integrating applications on the Web. The popularity of XML has resulted in a demand for development tools that are powerful, flexible, and easy to use. The minimum software required for XML development is a parser for processing XML documents. Other useful tools are XML and document type declaration (DTD) editors, and middleware products. Many development tools are available including products from vendors such as IBM, Microsoft, HP Bluestone, Sun Microsystems, ArborText, and webMethods.
