Java xml file read

Question

Creating an xml file in my Package and the XML file content is

<?xml version="1.0" encoding="UTF-8"?>
<main>
<sub>
<Key>TL</Key>
<value>Title</value>
</sub>
<sub>
<Key>DKN</Key>
<value>Docket No.</value>
</sub>
</main>

from the main class, i have declare a String Variable and passing the Following query

String query = "prabu<in>TL";

adove string Key is TL so now i want to read the XML file, with corresponding Key with Value and assign the value into an another string variable

String fieldName ="Title";

Can anyone please provide a suggestion how I can read the value from the xml file

If you did not simplify your XML, java XML properties would be an already existing solution.

The XML looks like:

<?xml version="1.0"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
    <entry key="TL">Title</entry>
    <entry key="DKN">Docket No.</entry>
</properties>

And Properties are handled as:

Properties properties = new Properties();
properties.loadFromXML(inputStream);

String key = "TL";
String defaultValue = "";
String value = properties.getProperty(key, defaultValue);
