Introduction

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

Parameters

GetTracking uses 5 params to help retrieve trackings in question.

1. trackingType: it refers to type of tracking wanted. (eg : order , product, baseArticle ...)
2. keys: it can handle 2 values, "trkID" or keys separated by ';' (eg: 'orderNumber;City;Phone')  if the key contains '_' at the first character, it means we look for metadata (_statusTracking, _creationDate ...)
   NB: all metadata will be explained in detail in another paragraph.
3.  values: the values must be ordered the same as 'keys'. if we're searching by 'trkID', 'values' should contain trkIDs separated by space ' '. eg : '121ee 123DD 55evr om432' 
   In the other case where we use values depending on keys, they must be separated by ';' as shown below : 
   if we take the last example in 'keys' param, 'orderNumber;City;Phone' , 'values' will be by example '1243;Paris;06070706053' .
4. limit: it defines the max number of tracking to retrieve. it's optional.
5. order: whether you want to order the list of trackings in a descending way or not by a certain key order. it's optional as long as you didn't fill then 

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;Brand' , 'Laptop;Dell')"></xsl:value-of>
