编码特殊的HTML字符< > /“在Java中 [英] Encoding special HTML characters < > / " in Java

问题描述

我正在使用Java 1.6.0

我正在寻找用Java编码特殊HTML字符的正确方法

My HTML

 < div id =sliceXML> Florida< DIV> 
  

我试图定义一个String xmlMatch作为内容这个案例佛罗里达州）的上述div标签通过使用下面的Java。不过，我相信我没有正确定义我的startTag或endTag。

My Java

 字符串testContent = contentPara; 
 String startTag =\sliceXML\>; 
 String endTag =< / div; 
 String xmlMatch = null; 
 
 int startPosition = testContent.indexOf（startTag）; 
 
 if（startPosition> 1）{
 
 int subStringIndex = startPosition + startTag.length（）; 
 int endPosition = testContent.indexOf（endTag，subStringIndex）; 
 
 if（endPosition> = startPosition）{
 xmlMatch = testContent.substring（subStringIndex，endPosition）; 
 out.println（xmlMatch.length（））; 
 
 //out.println (startTag）; 
 
 out.println（Florida.equals（xmlMatch））; 
 out.println（florida.equals（xmlMatch））; 
} 
} 
  

任何帮助都非常有用。这也可以让我回答以前的相关问题此处

$ b 解决方案 p>

正如我在下面解释的，我相信我的问题是在 String endTag =< / div; 为了解决这个问题，我简单地将我的结束标记更改为 String endTag =<;

I仍然不知道为什么会发生这种情况，如果有人能够回答，那将会很棒。

解决方案

我真的会使用HTML解析器，比如容易混淆的

p>它可以让你免于头痛，比如解析和处理字符实体和编码。

I am using Java 1.6.0

I am looking for the correct methods of encoding special HTML characters in Java

My HTML

 <div id="sliceXML">Florida</div>

I am trying to define a String xmlMatch as the content (in this case Florida) of the above div tag by using the below Java. However i believe i do not have my startTag or endTag defined correctly.

My Java

String testContent = contentPara;
String startTag = "\"sliceXML\">";                      
String endTag = "</div";                                        
String xmlMatch = null; 

int startPosition = testContent.indexOf(startTag);  

if(startPosition >1){

    int subStringIndex = startPosition + startTag.length();                                 
    int endPosition = testContent.indexOf(endTag, subStringIndex);              

    if(endPosition >= startPosition){
        xmlMatch = testContent.substring(subStringIndex, endPosition);
        out.println(xmlMatch.length()); 

    //out.println(startTag);

    out.println("Florida".equals(xmlMatch));
    out.println("florida".equals(xmlMatch));
}   
 }

Any help is much appricated. This would also allow me to answer a previous related question here

EDIT

WORK AROUND SOLUTION

As i explain below, i believe my issue was with the forward slash in String endTag = "</div"; To get past this problem i simply changed my end tag to String endTag = "<";

I still dont know why this happened, it would be great if someone could answer.

解决方案

I would really use an HTML parser, such as the confusingly-named JTidy (it's an HTML pretty-printer, but also gives you a DOM interface to the HTML structure).

It'll save you from headaches such as the parsing and handling character entities and encoding.
