Java jstl xml tag transform
The <x:transform>
tag in JSTL (JavaServer Pages Standard Tag Library) is used to transform an XML document using an XSLT stylesheet. Here's an example of how to use it:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/xml" prefix="x" %> <x:parse var="myXml"> <root> <item id="1">Item 1</item> <item id="2">Item 2</item> <item id="3">Item 3</item> </root> </x:parse> <x:transform xml="${myXml}" xslt="path/to/my/stylesheet.xsl" var="transformedXml"/> <x:out select="$transformedXml"/>
In this example, we use the <x:parse>
tag to parse an XML document into an object named myXml
. We then use the <x:transform>
tag to transform the myXml
object using an XSLT stylesheet located at path/to/my/stylesheet.xsl
. The transformed XML document is stored in a variable named transformedXml
.
Finally, we use the <x:out>
tag to output the transformed XML document.
Note that the xslt
attribute of the <x:transform>
tag can also be set to a string literal containing the XSLT stylesheet, like this:
<x:transform xml="${myXml}" xslt="<xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'><xsl:template match='root'><html><body> <xsl:for-each select='item'>- <xsl:value-of select='.'/> </xsl:for-each> </body></html></xsl:template></xsl:stylesheet>" var="transformedXml"/>
In this case, the XSLT stylesheet is defined directly within the JSP file as a string literal.
