XML非法属性值 [英] XML Illegal Attribute Value

问题描述

我在java中使用SAX解析器来读取一些XML。我给它的XML有问题并导致解析失败。这是错误消息：

11-18 10：25：37.290：W / System.err（3712）：org.xml.sax .SAXParseException：非法：< （位置：START_TAG< question text ='null'> @ 1：23 in java.io.InputStreamReader@4074c678）

我有一种感觉，它不喜欢XML中的字符串中有一些HTML标签。从语法的角度来看，我认为引号内的任何内容都会被忽略。另外，这里使用单引号是否有效？以下是一个例子：

 <测验> 
< question text =< img src ='// files / alex / hilltf.PNG'alt ='hill'style ='max-width：400px'/>在地图上以剪切表示。 > 
< answer text =1/> 
 < / question> 
< / quiz> 
  

解决方案

错误消息是正确的。 < 必须是标签的开始，并且不能出现在字符串中。它必须是& lt; 。我不相信报价是一个问题。

I am using the SAX parser in java to read some XML. The XML I am giving it has problems and is causing the parse to fail. Here is the error message:

11-18 10:25:37.290: W/System.err(3712): org.xml.sax.SAXParseException: Illegal: "<" inside attribute value (position:START_TAG <question text='null'>@1:23 in java.io.InputStreamReader@4074c678)

I have a feeling that it does not like the fact that I have some HTML tags inside of a string in the XML. I would think that anything inside the quotes gets ignored from a syntax standpoint. Also, is it valid to use single quotes here? Here is an example:

<quiz>
    <question text="<img src='//files/alex/hilltf.PNG' alt='hill' style='max-width:400px' />  is represented on map by cut. ">
        <answer text="1"/>
        <answer text="2" correct="true"/>
    </question>
</quiz>

解决方案

The error message is correct. A < must be the start of a tag, and cannot appear inside a string. It must be < instead. I don't believe the quotes is a problem.
