Mule ESB: xml to maps transformer produces empty hashmaps
Question
The configuration of my flow is:
<flow name="addVendors" doc:name="addVendors">
<file:inbound-endpoint path="/ws/esb/vendors/input/" moveToDirectory="/ws/esb/vendors/processed/" responseTimeout="10000" doc:name="File"/>
<file:file-to-string-transformer mimeType="text/xml" doc:name="File to String"/>
<jdbc-ee:xml-to-maps-transformer encoding="UTF-8" mimeType="text/xml" doc:name="XML to Maps"/>
<component class="com.myapp.integration.VendorsHelper" doc:name="Java"/>
<file:outbound-endpoint path="/ws/esb/vendors/output" responseTimeout="10000" doc:name="File"/>
</flow>
I'm trying to send the following xml:
<?xml version="1.0"?>
<book>
<note id="1">
note1
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
<author>Some author</author>
</note>
<note id="2">
note2
<to>Mark</to>
<from>Smith</from>
<heading>Invitation</heading>
<body>Invitation for birthday!</body>
<author>Some author</author>
</note>
</book>
The problem is that I get two empty hashmaps after xml-to-maps transformation. What is incorrect in my code? how to debug it?

As explained in the documentation of the transformer , the XML transformed by the xml-to-maps transformer must be compliant to a specific schema (provided in the documentation).
Here is an example of a valid XML document:
<table>
<record>
<field name="id" type="java.math.BigDecimal">0</field>
<field name="name" type="java.lang.String">hello</field>
</record>
</table>
So you need to use the XSL-T transformer to transform your XML into the expected XML format and then you can use the transformer.
