Introduction
IXpathExpression is a built-in expression language similar to the well-known Xpath language.
Use
•	The current usable syntax of IXpathExpression looks like the following :  trkType [ key1 {operator} value1 AND key2 {operator} value2 ...] 
                     eg : Product [ Price <10 AND Quantity= 3 AND Category = Food] 
•	The list of available operators  : 
 =	equals	 	
>=	greater or equal than	 	
>	greater than	 	
<=	less or equal	 	
<	less	 	
!=	different	 	
<>	between two number or date values	the two values are stored in a String as : "min;max"
Example : Product [ ExpirationDate <> 2020-02-02;2021-02-02	
#	not in an array of values 	the list is a String of values separated with ';' :
Example : Game [ Alias # FIFA;MINECRAFT ]	
€	in an array of values	the list is a String of values separated with ';' :
Example : Planet [  Name € Mercury;Earth]	
	
•	 
•	Metadata:
         There is the possibility to call values from metadata, such as creationDate , modificationDate, jobID , userID ... by inserting '_' (underscore) at the beginning of the alias           needed like : _creationDate , _modificationDate ... 
         Exemple :
<xsl:value-of select="ixf:GetTracking(Order[_envID = 'iXPath')"></xsl:value-of>
•	Links
        To call values from links, insert "!" at the beginning of the alias. For example: !key will refer to the linked value associated with the key.
<xsl:value-of select="ixf:GetTracking(Order[!Partner.Name = 'My Partner')"></xsl:value-of>
•	Extrametadata:
        To call values from extrametadata, insert "§" at the beginning of the alias. For example: §key will refer to the value associated with the key in extrametadata.
<xsl:value-of select="ixf:GetTracking(Order[§xTraMetaDataKey = 'Value')"></xsl:value-of>
