Dynamic Reference to Registered XSD

Question

I generate docs from SELECT like this,
<span style="color:red;">(I do not store this type of doc in DB/XDB)</span>:
<div style="color:blue;">
SELECT '&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;' || chr(10) ||
xmlelement
(&quot;ReinsuranceXfer&quot;,
xmlattributes
    ('http://blah.com/blah2/types/common' AS &quot;xmlns&quot;,
     'http://www.w3.org/2001/XMLSchema-instance' AS &quot;xmlns:xsi&quot;,
     'http://blah.com/blah2/types/common http://blah3/xmlschemas/Sales_v1.xsd'
     AS &quot;xsi:schemaLocation&quot;),
 xmlelement
    (&quot;SalesTransactions&quot;,
     xmlattributes('DirectTransactions' AS &quot;xsi:type&quot;).......
</div>
the schema &quot;Sales_v1.xsd&quot; is XDB-registered.
In stead of hard-coding <strong>&quot;Sales_v1.xsd&quot;</strong> in PL/SQL or View definition
I want to DYNAMICALLY reference the value, so when I switch to
version 2, registering the new schema (deleting the old one)
the value <strong>&quot;Sales_v2.xsd&quot;</strong>
can be dynamically referenced.
Is there a better/&quot;smarter&quot; way to achieve the dynamic reference
than this ?
<div style="color:blue;">
SELECT substr(any_path, instr(any_path, '/', -1) + 1) xsd
    FROM resource_view
   WHERE any_path LIKE '%Sales%.xsd';
</div>
thanks

You can't invoke methods on bits of String as if they were references to objects. (Java isn't like PHP in this regard.)
You can, however, use arrays as db suggested.
Let's say I have a hundred toggle buttons. I might give them names like "okButton" "exitButton" etc. Or I might make them elements of an array of buttons, buttonArr.
And I have a method toggle(int) that accepts an integer as input and verifies that the argument is within the range 1 to 100, throwing an exception if it is not. This method is intended to select the toggle button that corresponds to the integer it receives as input as selected. So the method would be implemented as
buttonArr.setSelected(true);
