Line 451:

The getValueByLang function returns the value of a property which has a qualifier {{Q|P407}} whose value has the given language code. The parameters are:

* The property ID passed in the unnamed parameter (or {{para|1}})

* The MediaWiki language code{{Q|P424}} to match the language whose code is given by {{para|lang|xx[-yy]}}. If no code is supplied, it uses the default language.

* 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 getValueByLang ====

In {{Q|Q7565108}} there is a property {{Q|P856}} that has multiple values, each of which has a qualifier {{Q|P407}}. We can return the property value whose {{Q|P407}} qualifier value (a WD item) itself has the {{Q|P424}} property that is "ja", i.e, {{Q|Q5287}}

* <code><nowiki>{{#invoke:WikidataIB |getValueByLang |qid=Q7565108 |P856 |lang=ja |fwd=ALL |osd=no |noicon=true}}</nowiki></code> → {{#invoke:WikidataIB |getValueByLang |qid=Q7565108 |P856 |lang=ja |fwd=ALL |osd=no |noicon=true}}

If {{para|lang}} is unspecified, we can obtain the same value with the default language (here that is the {{Q|Q1860}} and its {{Q|P424}} is "en")

* <code><nowiki>{{#invoke:WikidataIB |getValueByLang |qid=Q7565108 |P856 |fwd=ALL |osd=no |noicon=true}}</nowiki></code> → {{#invoke:WikidataIB |getValueByLang |qid=Q7565108 |P856 |fwd=ALL |osd=no |noicon=true}}
