Try Komodo Edit. It's free, open source, multi-platform and supports XML editing.

From the Komodo Edit online help:
XML AutoComplete and CallTips

Komodo supports XML autocomplete and calltips for basic XML as well as a number of XML dialects, including:

 HTML
 XHTML
 SGML
 RELAX
 RELAX NG
 RDF
 MXML
 XML Schema
 Atom
 Dublin Core
 DocBook
 WAP
 XSLT
 VXML
 SVG
 MathML
 XBL
 XUL
 XML Catalog

Support for additional XML dialects can be configured by adding an XML Catalog for the dialect in the SGML/XML Catalogs section of the Code Intelligence Preferences.

Komodo supports the following types of XML autocomplete:

• Autocomplete for elements: A list of elements available in the current namespace is supplied upon entering "<". If the current document's XML dialect is not recognized (i.e. it is not in the above list or in a configured catalog), the completion list is drawn from elements used in the document.
• Autocomplete for attributes: A list of attributes available within in the current element is supplied upon entering a space after the element name.
• Autocomplete for end-tags: A list (of length one) to close the current tag is supplied upon entering '

If the document does not have an XML declaration, autocomplete will default to XHTML 1.1. The DOCTYPE and namespace can be manually set under File Properties.
