  • 0

I have been using Jsoup for parsing my HTML files and so far it does a great job. However, it’s not able to parse any server tags ( <% … %> ). I decided to extend it but I cannot find an easy way to extend its Parser and all those private/package level classes (i.e. TreeBuilder, TransitionState … etc)…

So I started looking at Jericho as it claims it can parse server tags – however, its documentation is so poor that I cannot even get started easily. And seems like its API is not as friendly as what Jsoup provides – it’s not that straight forward to extract some nodes and move it around …

I wonder if anyone has the similar situation before and how you get it solved? In short, I just want to parse JSP files in Java. (Well .. please don’t ask me to implement one by myself ;p )

    Lastly I get a workaround: put server code block in a HTML comment block so that 1) server code can get executed correctly; 2) Jsoup can process the whole block as a HTML comment node without touching anything inside.

    e.g. 

    <!--
<%@ page language="java" errorPage="/error.jsp" pageEncoding="UTF-8" contentType="text/html;charset=UTF-8" %>
<%@ page import="com.systemcrossed.groupbuystart.webapp.display.DisplayHelper" %>
<%@ page import="com.systemcrossed.groupbuystart.webapp.util.JsonUtil" %>
<%@ page import="org.apache.commons.lang.StringEscapeUtils" %>
<%@ include file="/_sys/pages/public/incl/jspCommon.jsp" %>
-->
<!--<%
    // Java code here
%>-->
<html>
<head>
    ... html stuff

    It works well for me now! Hope ppl who got the same problem could get some help ! 😉
