This example parses an XML record received in the "body" field of the input record following the xPathMappings for each field name. The output structured record will be created using the type specified for each field in the "fieldTypeMapping". Only years and prices will be passed on for books with a price over 35.00:

For example, suppose the transform receives these input records:
...
offset | body |
|---|---|
1 | <bookstore><book category="cooking"><subcategory><type>Continental</type><genre>European |
...
cuisines</genre></subcategory><title |
...
lang="en">Everyday |
...
Italian</title><author>Giada |
...
DeLaurentiis</author><year>2005</year><price>30.00</price></book></bookstore> |
...
2 | <bookstore><book category="children"><subcategory><type>Series</type><genre>fantasy |
...
literature</genre></subcategory><title |
...
lang="en">Harry |
...
Potter</title><author>J. |
...
K. |
...
Rowling</author><year>2005</year><price>49.99</price></book></bookstore> |
...
The output records will contain:
...
category | title | year | price | subcategory |
|---|---|---|---|---|
cooking | Everyday Italian | null | null | <subcategory><type>Continental</type><genre>European cuisines</genre></subcategory> |
children | Harry Potter | 2005 | 49.99 | <subcategory><type>Series</type><genre>fantasy literature</genre></subcategory> |
Here, since the subcategory contains child nodes, the plugin will return the complete subcategory node (along with its child elements) as string as <subcategory><type>Continental</type><genre>European cuisines</genre></subcategory> . This is to ensure that the plugin returns a single XML event for a structured record instead of the two child events: <type>Continental</type> and <genre>European cuisines</genre>.
