Example of the nsprefix option

The following definition is used in the example
```
D info            DS                  QUALIFIED
D   type                        25A   VARYING DIM(2)
D   ns_type                     10A   VARYING DIM(2)
D   qty                         10I 0
D   price                        7P 3
D   ns_price                    10A   VARYING
```
Assume that file info3.xml contains the following
```
<abc:info xmlns:abc="http://www.abc.xyz"
          xmlns:def="http://www.def.xyz">
 <abc:type>Chair</abc:type>
 <abc:qty>3</abc:qty>
 <def:type>Modern</def:type>
 <abc:price>79.99</abc:price>
</abc:info>
```
XML-INTO options ns=remove nsprefix=ns_ are specified, so that the RPG programmer can obtain the namespace used for the XML name matching some of the RPG subfields. Option nsprefix=ns_ indicates that subfields beginning with NS_ are candidates for holding the namespace values.

The XML document has two elements that map to the RPG subfield TYPE: abc:type and def:type.

The TYPE subfield is defined with DIM(2) because there are two XML elements with the name type, after the namespace is removed. The NS_TYPE subfield is also defined with DIM(2) so that XML-INTO can place the namespace value for each occurrence of an XML name matching the TYPE subfield.

When XML-INTO handles the XML name abc:type, it will set the TYPE(1) subfield to the value 'Chair' and it will set the NS_TYPE(1) subfield to the value 'abc'.

When XML-INTO handles the XML name def:type, it will set the TYPE(2) subfield to the value 'Modern' and it will set the NS_TYPE(2) subfield to the value 'def'.

When XML-INTO handles the XML name abc:qty, it sets the QTY subfield to the value 3. There is no subfield with the name NS_QTY, so the namespace value is not saved in a subfield.

When XML-INTO handles the XML name abc:price, it will set the PRICE subfield to the value 79.99 and it sets the NS_PRICE subfield to the value 'abc'.
```
   xml-into info %xml('info3.xml'
                   : 'doc=file ns=remove nsprefix=ns_');
   // info.type(1) = 'Chair'
   // info.ns_type(1) = 'abc'
   // info.type(2) = 'Modern'
   // info.ns_type(2) = 'def'
   // info.qty = 3
   // info.price = 79.99
   // info.ns_price = 'abc'
