Jstl_xml

One: Description

1. If there is reprint please indicate the source
2. Properties that must contain properties, including default values, are separated by a carriage return

Two: XML tag library

The main function of XML tag library is to facilitate the operation of XML in JSP pages, this blog does not do a detailed explanation, <x:out>,<x:set>,<x:if>,<x:when>,<x:choose The >,<x:forEach>,<x:otherwise>,<x:param> tag is basically the same as the tag in the core tag library, the only difference being that these tokens are the ones that handle the XML content.

Three: XML tags

1. <x:out>,<x:set>,<x:if>,<x:when>,<x:choose>,<x:foreach>,<x:otherwise The >,<x:param> tag is basically the same as the tag in the core tag library, the only difference being that these tokens are the ones that handle the XML content.

2. <x:parse> Mark

Sample code: XML File contents:

<?xml version= "1.0" encoding= "UTF-8"?> <peoples>         <people>                   <name> Darren Brown </name >                   <sex>man</sex>         </people>                 <people>                   <name> Everton g</name>                   <sex>little man</sex>         </people>                 <people>                   <name> Charlotte Lingling </name >                   <sex>women</sex>         </people>                 <people>                   <name> Houston • Magician </ name>                   <sex>bigman</sex>         </people></peoples>

Transformation of XSL style sheets can be implemented
Example code:
<?xml version= "1.0" encoding= "UTF-8"? ><xsl:stylesheet version= "1.0" xmlns:xsl= "Http://www.w3.org/1999/XSL /transform ">       <xsl:template match="/">              <!--todo:auto-generated template----              for-each select= "Peoples/people" >              <tr>                     <td><xsl:value-of select= "name"/></td>                     <td><xsl:value-of select= "Sex"/></ td>              </tr>              </xsl:for-each>       </table></body>
