我在下面有以下(测试)XML文件和使用StaX的Java代码。我想将此代码应用于大约30 GB但具有相当小元素的文件,因此我认为StaX是一个不错的选择。我收到以下错误:
线程中的异常" main" javax.xml.stream.XMLStreamException:[row,col]处的ParseError:[1,1]消息:prolog中不允许使用内容 at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:598) at at.tuwien.mucke.util.xml.staxtest.StaXTest.main(StaXTest.java:18) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 在java.lang.reflect.Method.invoke(Method.java:601) 在com.intellij.rt.execution.application.AppMain.main(AppMain.java:120)

这里是代码:
package xml.staxtest;
import java.io.*;
import javax.xml.stream.*;
public class StaXTest {
public static void main(String[] args) throws Exception {
XMLInputFactory xif = XMLInputFactory.newInstance();
XMLStreamReader streamReader = xif.createXMLStreamReader(new FileReader("D:/Data/testFile.xml"));
while(streamReader.hasNext()){
int eventType = streamReader.next();
if(eventType == XMLStreamReader.START_ELEMENT){
System.out.println(streamReader.getLocalName());
}
//... more to come here later ...
}
}
}
答案 0 :(得分:1)
解决了!
我在定义<?xml version="1.0" encoding="ISO-8859-1" ?>
中添加了编码,我必须将其存储在ANSI中(如Notepad ++假设为UTF-8)。愚蠢!
