JSTL XML <x:parse> Tag
The <x:parse> tag is used to parse XML data specified either via an attribute or in the tag body.
Attribute:
The <x:parse> tag has following attributes:
Attribute | Description | Required | Default |
var | A variable that contains the parsed XML data | No | None |
xml | Text of the document to parse (String or Reader) | No | Body |
systemId | The system identifier URI for parsing the document | No | None |
filter | The filter to be applied to the source document | No | None |
doc | XML document to be parsed | No | Page |
scope | Scope of the variable specified in the var attribute. | No | Page |
varDom | A variable that contains the parsed XML data. | No | Page |
scopeDom | Scope of the variable specified in the varDom attribute. | No | Page |
Example:
Following example shows how parse can be used to read external XML file and it can be parsed:
We have seen how we can parse XML from the body of the given document. Now let us put following content in books.xml file:
<books>
<book>
<name>Padam History</name>
<author>ZARA</author>
<price>100</price>
</book>
<book>
<name>Great Mistry</name>
<author>NUHA</author>
<price>2000</price>
</book>
</books>
|
Now try the following main.jsp, keeping in the same directory:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>
<html>
<head>
<title>JSTL x:parse Tags</title>
</head>
<body>
<h3>Books Info:</h3>
<c:import var="bookInfo" url="http://localhost:8080/books.xml"/>
<x:parse xml="${bookInfo}" var="output"/>
<b>The title of the first book is</b>:
<x:out select="$output/books/book[1]/name" />
<br>
<b>The price of the second book</b>:
<x:out select="$output/books/book[2]/price" />
</body>
</html>
|
Now try to access above JSP using http://localhost:8080/main.jsp, this would produce following result:
Books Info:
The title of the first book is:Padam History
The price of the second book: 2000
