尝试解析XML时出现MalformedByteSequenceException

Question

我有来自维基百科的以下.gpx数据:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<gpx xmlns="http://www.topografix.com/GPX/1/1" creator="byHand" version="1.1" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd">
  <wpt lat="39.921055008" lon="3.054223107">
    <ele>12.863281</ele>
    <time>2005-05-16T11:49:06Z</time>
    <name>Cala Sant Vicenç - Mallorca</name>
    <sym>City</sym>
  </wpt>
</gpx>

当我调用我的解析方法时,我得到一个例外(见下文).电话看起来像这样:

Document tmpDoc = getParsedXML(currentGPX);

我的解析方法看起来像这样(标准解析代码,没有什么令人兴奋的......):

    public static Document getParsedXML(String fileWithPath){
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db;
    Document doc = null;
    try {
        db = dbf.newDocumentBuilder();
        doc = db.parse(new File(fileWithPath));
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    } catch (SAXException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return doc;
    }

这个简单的代码抛出以下异常:

我猜错误在于第一个文件的格式,但我不知道究竟在哪里.你能给我一个提示吗？

Answer 1

我建议你的文件没有以UTF-8格式保存.
