如何在JSP页面上显示xml文件中定义的html元素

Question

I'm currently working on a web application where in I'm continuously adding new columns to the database tables for new projects. I don't want to keep any dependency on Java program to display new column details on JSP page hence I want to define each and every html element/components including attributes in the XML file and want to load them dynamically on the web page (JSP). I know we can read below XML file using any Java XML parser but actual problem is while placing the html elements on the JSP page.

I'm using struts 2 framework.

Sample XML file

<?xml version= "1.0" encoding ="UTF-8"?>
<!DOCTYPE ROOTCOMPONENT [
<!ATTLIST COMPONENT
    COMP_NAME CDATA #REQUIRED
    COMP_TYPE CDATA #REQUIRED
    LABLE CDATA #IMPLIED
    SIZE CDATA #IMPLIED
    TABLE_NAME CDATA #IMPLIED  
    COLUMN_NAME CDATA #IMPLIED  
>
]>
<ROOTCOMPONENT >
<COMPONENT COMP_NAME="INPUT" COMP_TYPE="TEXT"  LABLE="User Name" /> 
<COMPONENT COMP_NAME="INPUT" COMP_TYPE="PASSWORD"  LABLE="Password"/> 
</ROOTCOMPONENT>

Would it be possible? Does anyone knows how it can be achieved? Any sample code snippet would be really helpful.

您可以使用XML标记库的“转换标记”在JSP页面中使用XSLT转换XML，而无需任何其他Java代码。
