Java jstl xml tag param-IGI

The <x:param> tag in JSTL (JavaServer Pages Standard Tag Library) is used to pass parameters to an XSLT transformation. 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:transform xml="${myXml}" xslt="${myXslt}">
  <x:param name="param1" value="foo"/>
  <x:param name="param2" value="bar"/>
</x:transform>

In this example, we use the <x:transform> tag to apply an XSLT transformation to an XML document stored in the myXml variable. The xslt attribute specifies the path to the XSLT file to use for the transformation.

Within the <x:transform> tag, we use the <x:param> tag to pass parameters to the XSLT transformation. The name attribute specifies the name of the parameter, and the value attribute specifies its value.

In the XSLT file, we can access the values of these parameters using the <xsl:param> element, like this:

<xsl:param name="param1"/>
<xsl:param name="param2"/>

<xsl:template match="/">
  <html>
    <head><title><xsl:value-of select="$param1"/></title></head>
    <body>
      <p><xsl:value-of select="$param2"/></p>
    </body>
  </html>
</xsl:template>

In this XSLT file, we use the <xsl:param> element to declare two parameters named param1 and param2. We then use the <xsl:value-of> element to access their values and insert them into the HTML output. Note that the values of these parameters are passed from the JSP page using the <x:param> tag.
