Inheritance

System.Object

Namespace: Umbraco.Cms.Core.Xml

Assembly: Umbraco.Core.dll

Syntax

public class UmbracoXPathPathSyntaxParser

Methods

ParseXPathQuery(String, Nullable<Int32>, Func<Int32, Nullable<IEnumerable<String>>>, Func<Int32, Boolean>)

Declaration

public static string ParseXPathQuery(string xpathExpression, int? nodeContextId, Func<int, IEnumerable<string>?> getPath, Func<int, bool> publishedContentExists)

Parameters

Type	Name	Description
System.String	xpathExpression
System.Nullable<System.Int32>	nodeContextId
Func<System.Int32, System.Nullable<IEnumerable<System.String>>>	getPath
Func<System.Int32, System.Boolean>	publishedContentExists

Returns

Type	Description
System.String

ParseXPathQuery(String, Nullable<Int32>, Nullable<Int32>, Func<Int32, Nullable<IEnumerable<String>>>, Func<Int32, Boolean>)

Parses custom umbraco xpath expression

Declaration

public static string ParseXPathQuery(string xpathExpression, int? nodeContextId, int? parentId, Func<int, IEnumerable<string>?> getPath, Func<int, bool> publishedContentExists)

Parameters

Type	Name	Description
System.String	xpathExpression	The Xpath expression
System.Nullable<System.Int32>	nodeContextId	The current node id context of executing the query - null if there is no current node.
System.Nullable<System.Int32>	parentId	The parent node id of the current node id context of executing the query. With this we can determine the $parent and $site parameters even if the current node is not yet published.
Func<System.Int32, System.Nullable<IEnumerable<System.String>>>	getPath	The callback to create the nodeId path, given a node Id
Func<System.Int32, System.Boolean>	publishedContentExists	The callback to return whether a published node exists based on Id

Returns

Type	Description
System.String
