The <x:parse> tag is used to parse XML data specified either via an attribute or in the tag body.
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 |
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 HistoryThe price of the second book: 2000 |
