=== Function getQualifierValue ===

The getQualifierValue function is for use when we want to fetch the value of a qualifier. We need to know the property and the value of the property that the qualifier relates to. The parameters are:
* The property ID passed in the unnamed parameter (or {{para|1}})
* The target value for that property in {{para|pval}}
* The qualifier ID for that target value in {{para|qual}}
* The same parameters to implement whitelisting and blacklisting of the property as in getValue
* Optional boolean to specify whether only sourced values of the property are returned (defaults to "no") in {{para|onlysourced}}
* Optional item ID for arbitrary access in {{para|qid}}
* The same parameters to format output as in getValue

==== Example of getQualifierValue ====
In {{Q|Q1513315}} there is a property {{Q|P793}}, which has a value {{Q|Q385378}}. That has two qualifiers, {{Q|P580}} and {{Q|P582}}. To get the start date:
* <code><nowiki>{{#invoke:WikidataIB |getQualifierValue |P793 |pval=Q385378 |qual=P580 |name=xyz |fetchwikidata=ALL }}</nowiki></code>
In [[South Pole Telescope]] it returns:
* {{#invoke:WikidataIB |getQualifierValue |P793 |pval=Q385378 |qual=P580 |name=xyz |fetchwikidata=ALL |qid=Q1513315}}
