Introduction

In this section, we will go throw an XSL function to get trackings by trkID or using Keys/Values.

Parameters

GetTracking uses 4 params to help retrieve trackings in question.

1. xpathExpression: read the IXpathExpression for more details (IXpathExpression)
2. limit: it defines the max number of tracking to retrieve. it's optional. (Optional)
3. order: whether you want to order the list of trackings in a descending way or not by a certain key order. The default value is 'trkID' and it's optional as long as you fill in the limit value. (Optional)
4. projection: you can return only some wanted fields instead of fetching the integrity of tracking object. (Optional)

Uses

We suppose that we have a tracking type named Product. It has 3 data (Name, Brand, and Country).

if we want to get Product by key values 

 <xsl:value-of select="ixf:GetTracking('Product [Name == Laptop AND Brand == Dell AND _statusTracking==Delivered ]')"></xsl:value-of>

Searching by trkIDs :

Set the limit value to get only 4 elements  :

Add an order by Country : 

if you want to add an order without filling the limit, you must put 0 as a value to it :
