Defining Sitemap Nodes in XML

The following is a simple sitemap XML file that can be used with the MvcSiteMapProvider:

<?xml version="1.0" encoding="utf-8" ?> 
<mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0"
            xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0 MvcSiteMapSchema.xsd">

  <mvcSiteMapNode title="Home" controller="Home" action="Index" changeFrequency="Always" updatePriority="Normal"> 
    <mvcSiteMapNode title="Browse Store" controller="Store" action="Index" /> 
    <mvcSiteMapNode title="Checkout" controller="Checkout" /> 
  </mvcSiteMapNode> 
</mvcSiteMap>

Note: There must be exactly 1 root mvcSiteMapNode in the configuration file and the rest of the mvcSiteMapNode elements should be defined below the root node.

The following attributes can be given on an XML node element:

Attribute	Req'd	Default	Description
key	No	(autogenerated)	The unique identifier for the node.
url	Cond.	(autogenerated based on routes)	The URL represented by the node. Required if Controller and Action are not provided.
route	No	(empty)	Can optionally be specified to bind the node URL generation to a specific route.
title	Yes	(empty)	The title of the node. Localizable.
description	No	(empty)	Description of the node. Localizable. By default this value will be put into the HTML title attribute of the link.
area	No	(empty)	The MVC area for the sitemap node. If not specified, it will be inherited from a node higher in the hierarchy.
controller	Yes	(empty)	The MVC controller for the sitemap node. Case-sensitive! If not specified, it will be inherited from a node higher in the hierarchy.
action	Cond.	(empty)	The MVC action method for the sitemap node. Required if URL is not specified.
roles	No	(empty)	Comma-separated list of roles allowed to access the node and its child nodes.
resourceKey	No	(empty)	Optional implicit resource key for use during localization of the node.
clickable	No	true	Is the node clickable or just a grouping node?
inheritedRouteParameters	No	(empty)	Route parameters that should be inherited from the parent sitemap node.
dynamicNodeProvider	No	(empty)	A class name implementing MvcSiteMapProvider.IDynamicNodeProvider and providing dynamic nodes for the site map. These nodes are cached, not per-request.
urlResolver	No	Sitemap provider's SiteMapNodeUrlResolver instance	Class that will be used to generate URLs for sitemap nodes.
visibilityProvider	No	(empty); returns true	Class that will be used to determine visibility for a sitemap node. Default setting can be overridden by the configuration/appSettings value "MvcSiteMapProvider_&arr; DefaultSiteMapNode&arr; VisibiltyProvider".
visibility	No	(empty)	Optional extra data that can be passed to a visibility provider to make convention-based visibility. Example from demo: visibility="SiteMapPathHelper,!*"
cacheResolvedUrl	No	true	Should the resolved URL be cached (true) or resolved on each request (false)? If the preservedRouteParameters attribute is used, this setting will be ignored.
targetFrame	No	(empty)	Optional target frame for the node link.
imageUrl	No	(empty)	Optional image to be shown by supported HtmlHelpers. Localizable.
preservedRouteParameters	No	(empty)	Optional preserved route parameter names (= values that will be used from the current request route).
canonicalUrl	No	(empty)	Optional. The primary URL for what is completely or mostly duplicated content on the current node. The value may be an absolute URL (in the current site or in an external site), a rooted URL starting with '~/', or a relative URL. Cannot be used in conjunction with canonicalKey.
canonicalKey	No	(empty)	Optional. The key value for the node that contains the primary copy of the content for the current node, if it is largely similar. Cannot be used in conjunction with canonicalUrl.
metaRobotsValues	No	(empty)	Optional. A space-delimited list of values to apply to the robots meta tag. These will apply to all robots that crawl the site. Allowed values: index, noindex, follow, nofollow, none, noarchive, nocache, nosnippet, nopreview, noodp, noydir.
lastModifiedDate	No	(empty)	Last modified date for the node. Will be output to sitemaps XML for search engines.
changeFrequency	No	Undefined	Change frequency for the node. Will be output to sitemaps XML for search engines.
updatePriority	No	Undefined	Update priority for the node. Will be output to sitemaps XML for search engines.
httpMethod	No	GET	The HTTP method that will be used to check node accessibility. This value is used to select correct controller action if a controller has multiple action accepting different HTTP verbs. Set to * or Request to use HTTP method of current request.
order	No	0	The sort order the node will be displayed in the Menu and SiteMap HTML helpers relative to its sibling nodes.
(custom name)	No	(empty)	Any attributes not defined in this list will automatically be parsed and added to the node.Attributes dictionary. Localizable (string data type only).

XML Inheritance

Default Behavior

By default, "area" and "controller" (route values only) are automatically inherited from the parent node if they are not explicitly specified. This allows you to use fewer attributes when configuring nodes to make the XML less verbose.

The following two XML declarations will produce exactly the same results, however as you can see the second one requires less markup because it is taking advantage of the default inheritance behavior.

<?xml version="1.0" encoding="utf-8" ?>
<mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0"
            xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0 MvcSiteMapSchema.xsd">

    <mvcSiteMapNode title="Home" controller="Home" action="Index">
        <mvcSiteMapNode title="About" controller="Home" action="About"/>
        <mvcSiteMapNode title="Contact" controller="Home" action="Contact"/>
        <mvcSiteMapNode title="Products" controller="Products" action="Index">
            <mvcSiteMapNode title="Flashlight" controller="Products" action="Details" id="1"/>
            <mvcSiteMapNode title="AA Battery" controller="Products" action="Details" id="2"/>
        </mvcSiteMapNode>
        <mvcSiteMapNode title="Administration" area="Admin" controller="Home" action="Index">
            <mvcSiteMapNode title="Manage Products" area="Admin" controller="Products" action="Manage"/>
        </mvcSiteMapNode>
    </mvcSiteMapNode>

</mvcSiteMap>

<?xml version="1.0" encoding="utf-8" ?>
<mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0"
            xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-4.0 MvcSiteMapSchema.xsd">

    <mvcSiteMapNode title="Home" controller="Home" action="Index">
        <mvcSiteMapNode title="About" action="About"/>
        <mvcSiteMapNode title="Contact" action="Contact"/>
        <mvcSiteMapNode title="Products" controller="Products" action="Index">
            <mvcSiteMapNode title="Flashlight" action="Details" id="1"/>
            <mvcSiteMapNode title="AA Battery" action="Details" id="2"/>
        </mvcSiteMapNode>
        <mvcSiteMapNode title="Administration" area="Admin" controller="Home" action="Index">
            <mvcSiteMapNode title="Manage Products" controller="Products" action="Manage"/>
        </mvcSiteMapNode>
    </mvcSiteMapNode>

</mvcSiteMap>

inheritedRouteParameters

You can also specify additional route values to inherit, including custom attributes, by adding the name of the value to the inheritedRouteParameters. Multiple values should be separated by a comma.

The following 2 XML declarations will have exactly the same result.

<?xml version="1.0" encoding="utf-8" ?>

        <mvcSiteMapNode title="Products" controller="Products" action="Index">
            <mvcSiteMapNode title="Flashlight" action="Details" id="1" type="product"/>
            <mvcSiteMapNode title="AA Battery" action="Details" id="2" type="accessory"/>
        </mvcSiteMapNode>
    </mvcSiteMapNode>
