| 42 | ))) | ||
| 43 | |||
| 44 | 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 ... | ||
| 45 | |||
| 46 | Exemple : | ||
| 47 | |||
| 48 | {{code language="XML"}} | ||
| 49 | <xsl:value-of select="ixf:GetTracking(Order[_envID = 'iXPath')"></xsl:value-of> | ||
| 50 | {{/code}} | ||

| 53 | **Links** | ||
| 54 | ))) | ||
| 55 | |||
| 56 | **~ **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. | ||
| 57 | |||
| 58 | {{code language="XML"}} | ||
| 59 | <xsl:value-of select="ixf:GetTracking(Order[!Partner.Name = 'My Partner')"></xsl:value-of> | ||
| 60 | {{/code}} | ||
| 61 | |||
| 62 | * **Extrametadata:** | ||
| 63 | |||
| 64 | 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. | ||
| 65 | |||
| 66 | {{code language="XML"}} | ||
| 67 | <xsl:value-of select="ixf:GetTracking(Order[§xTraMetaDataKey = 'Value')"></xsl:value-of> | ||
