Could not read properly data from XML while inserting data into PostgreSQL using Mule ESB, Mule Studio

Question

I have an xml file as under

<Families>
    <Family>
        <title>Mr</title>
        <name>Xyz</name>    
    </Family>
    <Family>
        <title>Mr</title>
        <name>Mno</name>    
    </Family>
</Families>

I am trying to read the file and store the data into PostgreSQL database. My configuration xml file is as under

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:jdbc="http://www.mulesoft.org/schema/mule/jdbc" xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" version="CE-3.3.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="

        <jdbc:outbound-endpoint exchange-pattern="one-way" queryKey="InsertQuery" queryTimeout="-1" connector-ref="Database-Connector" doc:name="Database"/>
    </flow>
</mule>

While running , I am receiving the below error (mainly)

Exception stack is:
1. ERROR: syntax error at or near ":"
  Position: 52(SQL Code: 0, SQL State: + 42601) (org.postgresql.util.PSQLException)
  org.postgresql.core.v3.QueryExecutorImpl:2157 (null)
2. ERROR: syntax error at or near ":"
  Position: 52 Query: INSERT INTO "tblTest"(title, name)VALUES (#xpath://title,#xpath://name) Parameters: [](SQL Code: 0, SQL State: + 42601) (java.sql.SQLException)
  org.apache.commons.dbutils.QueryRunner:540 (null)

I am suspecting that there is something wrong in

"VALUES (#xpath://title,#xpath://name)"

Can someone help me out as what is wrong?

Thanks in advance

Answer 1

This is not a valid expression language syntax, which are like #[ ... ], nor a valid MEL XPath expression (see http://www.mulesoft.org/documentation/display/MULE3USER/Mule+Expression+Language#MuleExpressionLanguage-Xpath).

Use: #[xpath('//title').text]

Note that I added .text because you want the text content of the selected DOM element, not the DOM element itself.
