XML Editors

If you are serious about XML, you will benefit from using a professional XML Editor.

XML is Text-based
XML is a text-based markup language.
One great thing about XML is that XML files can be created and edited using a simple text-editor like Notepad.
However, when you start working with XML, you will soon find that it is better to edit XML documents using a professional XML editor.

Why Not Notepad?
Many web developers use Notepad to edit both HTML and XML documents because Notepad is included with the most common OS and it is simple to use. Personally I often use Notepad for quick editing of simple HTML, CSS, and XML files.
But, if you use Notepad for XML editing, you will soon run into problems.
Notepad does not know that you are writing XML, so it will not be able to assist you.

Why an XML Editor?
Today XML is an important technology, and development projects use XML-based technologies like:
·   XML Schema to define XML structures and data types
·   XSLT to transform XML data
·   SOAP to exchange XML data between applications
·   WSDL to describe web services
·   RDF to describe web resources
·   XPath and XQuery to access XML data
·   SMIL to define graphics
To be able to write error-free XML documents, you will need an intelligent XML editor!

XML Editors
Professional XML editors will help you to write error-free XML documents, validate your XML against a DTD or a schema, and force you to stick to a valid XML structure.
An XML editor should be able to:
·   Add closing tags to your opening tags automatically
·   Force you to write valid XML
·   Verify your XML against a DTD
·   Verify your XML against a Schema
·   Color code your XML syntax
