Sax解析和编码 [英] Sax parsing and encoding

问题描述

我有一个在解析RSS和Atom文件时遇到SAX问题的联系人。根据他的说法，就好像来自Item元素的文本被截断为撇号或有时是重音字符。编码似乎也有问题。

I have a contact that is experiencing trouble with SAX when parsing RSS and Atom files. According to him, it's as if text coming from the Item elements is truncated at an apostrophe or sometimes an accented character. There seems to be a problem with encoding too.

我已经尝试过SAX了，我也有一些截断，但是还没有进一步深入挖掘。如果有人在此之前解决了这个问题，我会很感激。

I've given SAX a try and I have some truncating taking place too but haven't been able to dig further. I'd appreciate some suggestions if someone out there has tackled this before.

这是在ContentHandler中使用的代码：

This is the code that's being used in the ContentHandler:

public void characters( char[], int start, int end ) throws SAXException {
//
    link = new String(ch, start, end);

编辑：编码问题可能是因为我知道Java可以在字节数组中存储信息Unicode。

The encoding problem might be due to storing information in a byte array as I know Java works in Unicode.

推荐答案

不保证characters（）方法在一次传递中为您提供文本元素的完整字符内容 - 全文可能跨越缓冲区边界。您需要在开始和结束元素事件之间自己缓冲字符。

The characters() method is not guaranteed to give you the complete character content of a text element in one pass - the full text may span buffer boundaries. You need to buffer the characters yourself between the start and end element events.

例如

StringBuilder builder;

public void startElement(String uri, String localName, String qName, Attributes atts) {
   builder = new StringBuilder();
}

public void characters(char[] ch, int start, int length) {
   builder.append(ch,start,length);
}

public void endElement(String uri, String localName, String qName) {
  String theFullText = builder.toString();
}
