Whilst editing XML files SharpDevelop provides namespace,
element, attribute and attribute value completion based on its
On typing the = character, after the xmlns attribute, a list of
namespaces will be shown. A namespace in the list can be selected
in a similar way to code completion by using the up and down cursor
keys, or by typing in the first few characters of the namespace,
and then pressing the Tab key to insert the namespace.
On typing an opening tag a list of elements that can be added at
the current location will be displayed.
On typing a space character after an element name a list of
attributes for that element will be shown. Inserting the attribute
will also insert the attribute value quotes ready for you to type
in its value.
Attribute Value Completion
On typing the first character of the attribute value a list of
possible values, as inferred from the schema, are displayed.
If the schema contains any annotation then this will be
To validate an xml document against its schema, first associate
a namespace with it using the xmlns attribute, then from the
XML menu select Validate XML.
Errors will be shown in the Output window and the
Clicking an entry in the Errors window will move the
cursor to the position of the error.
The XML schemas that SharpDevelop is aware of can be viewed and
configured from the options dialog box. From the Tools menu
select Options..., expand the Text Editor category
and select XML Schemas.
In the Schemas group box schemas that have been added by
you are highlighted in black text. System schemas, those that are
installed with the XML Editor, are displayed in grey text. Only
schemas that have been added by you can be removed. Clicking the
Add button opens up the open file dialog allowing you to
browse to an .xsd file and add it.
The File Extensions group box shows default associations
between a file extension and a schema. For example, .build
files could be associated with a NAnt schema, then whenever a
.build file is opened it automatically gets XML completion
for that schema without having to specify an xmlns attribute.
Specifying an xmlns attribute will override the default schema
association. To associate a schema with an xml file extension click
the browse button and select a schema from
The Prefix text box is used to specify the default
namespace prefix associated with an xml element. This prefix will
be used in the completion list (eg. "xs:schema").
