首先，我是这个 java/android 开发世界的新手，所以跟我说吧，我可能会问一些相对新手的问题:)。
不管怎样，我现在一整天都在解决这个问题，我自己无法找出任何解决方案，我在网上搜索了一些绕过这个问题的想法。
我正在尝试开发一个 Android 应用程序，它可以解析外部 XML 文件中的数据。
我的解析器看起来像这样:
public class NewSAXHandler implements ContentHandler
{
private String DEBUGTAG = "NewSAXHandler";
public static setNews news = null;
boolean currentElement = false;
String currentValue = null;
public static setNews getNews()
{
return news;
}
public static void setNewsList(setNews news)
{
NewSAXHandler.news = news;
}
@Override
public void startDocument() throws SAXException {
// TODO Auto-generated method stub
}
@Override
public void endDocument() throws SAXException {
// TODO Auto-generated method stub
}
@Override
public void startElement(String uri, String localName, String qname, Attributes attr) throws SAXException
{
currentElement = true;
if (localName.equalsIgnoreCase("channel"))
news = new setNews();
Log.d(DEBUGTAG, localName);
}
@Override
public void endElement(String uri, String localName, String qName) throws SAXException
{
if (localName.equalsIgnoreCase("title"))
{
news.setHeadline(currentValue);
Log.d(DEBUGTAG, localName);
Log.d(DEBUGTAG, currentValue);
}
else if (localName.equalsIgnoreCase("pubdate"))
{
news.setDate(currentValue);
Log.d(DEBUGTAG, localName);
Log.d(DEBUGTAG, currentValue);
}
}
@Override
public void characters(char[] ch, int start, int length) throws SAXException
{
if (currentElement)
{
currentValue = new String(ch, start, length).replaceAll("\\r\\n|\\r|\\n", " ");
currentElement = false;
}
}
@Override
public void ignorableWhitespace(char[] ch, int start, int length)throws SAXException
{
}
@Override
public void endPrefixMapping(String prefix) throws SAXException
{
}
@Override
public void processingInstruction(String target, String data)throws SAXException
{
}
@Override
public void setDocumentLocator(Locator locator)
{
}
@Override
public void skippedEntity(String name) throws SAXException
{
}
@Override
public void startPrefixMapping(String prefix, String uri)throws SAXException
{
}
}
XML 文件解析自:

看来错误来自于 ´ 字符。
我看不到编码，因为它不在 XML 文件中，但我猜它是 UTF-8。
我还尝试过使用 StringBuilder 来存储每个字符，但没有任何运气。
我以为 XML 解析器会自己转换这些特殊字符，但它似乎不喜欢它们。
如果我尝试解析此文件:
http://www.hltv.org/forum.rss.php这样效果会更好。
大家有什么新想法吗？
**如果您需要更多我的代码，请说出来:)

最佳答案
问题出在菲利普上面所说的编码上。
我刚刚将以下内容添加到我的代码中:
InputSource is = new InputSource(url.openStream());
is.setEncoding("ISO-8859-1");
Reader.parse(is);
关于java - SAX XML 解析器在处理特殊字符时遇到麻烦，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7881831/
