Get Web Content/Journal Article Fields Data Programmatically using SAX Parser

We already see in my previous blog on  Structues and Tempelates  that Liferay Stores Structues in xml format. So if you create a Web Content using Structures and Template and want to get the value of fields programmatically , than you can use SAXReaderUtil Class of Liferay. This class is used to parse xml content.

Ex- I already Created a Structure MOBILE_STRUCTURE which contain 5 fields Brand,Model,Description,Camera and Price.Now i create web contents Sony Xperia C using this structures .This data is save in journalarticle table as:-

Here the Content column store the data in xml as:-

	<?xml version="1.0"?>
	<root available-locales="en_US" default-locale="en_US">
	<dynamic-element name="Brand" index="0" type="text" index-type="keyword">
	<dynamic-content language-id="en_US"><![CDATA[Sony]]></dynamic-content>
	</dynamic-element>
	<dynamic-element name="Model_Number" index="0" type="text" index-type="keyword">
	<dynamic-content language-id="en_US"><![CDATA[Experia C]]></dynamic-content>
	</dynamic-element>
	<dynamic-element name="Description" index="0" type="text" index-type="keyword">
	<dynamic-content language-id="en_US"><![CDATA[Contain Front Camera]]></dynamic-content>
	</dynamic-element>
	<dynamic-element name="Camera" index="0" type="list" index-type="keyword">
	<dynamic-content language-id="en_US"><![CDATA[Yes]]></dynamic-content>
	</dynamic-element>
	<dynamic-element name="Price" index="0" type="text" index-type="keyword">
	<dynamic-content language-id="en_US"><![CDATA[12000]]></dynamic-content>
	</dynamic-element>
	</root>

So What if we want to fetch the fields like Price of Sony Xperia C programmatically. Just use  SAXReaderUtil as:-

	Document document = SAXReaderUtil.read(journalArticleObject.getContentByLocale(Locale.ENGLISH.toString()));
	Node brandNode = document.selectSingleNode("/root/dynamic-element[@name='Brand']/dynamic-content");
	String brand = brandNode.getText();
	Node modelNumberNode = document.selectSingleNode("/root/dynamic-element[@name='Model_Number']/dynamic-content");
	String modelNumber = modelNumberNode.getText();
	Node descriptionNode = document.selectSingleNode("/root/dynamic-element[@name='Description']/dynamic-content");
	String description = descriptionNode.getText();
	Node cameraNode = document.selectSingleNode("/root/dynamic-element[@name='Camera']/dynamic-content");
	String camera = cameraNode.getText();
	Node priceNode = document.selectSingleNode("/root/dynamic-element[@name='Price']/dynamic-content");
	String price = priceNode.getText();
