Java无法从字节生成xml

我必须在客户端创建xml文档，将其转换为字节数组，并在服务器端执行相反的顺序

我的xml是：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<dirStruct>
<file modified="1398855221782" name="sharedFolder\hey.txt"/>
</dirStruct>

。。。输入数据不为null，已向上验证

例外情况是：

[Fatal Error] :1:138: Content is not allowed in trailing section.
org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 138; Content is not allowed in trailing section.

我哪里错了

====================================

客户端：

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Element root = doc.createElement("dirStruct");
doc.appendChild(root);

Element node = doc.createElement("file");
node.setAttribute("name", file.toString());
node.setAttribute("modified", Long.toString(file.lastModified()));
root.appendChild(node);

TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(stream);
transformer.transform(source, result);

。。。流是由tearrayoutputstream

生成的

如果我将
stream
更改为
System.out
，我也会得到正确的结果

To字节数组就是
data=stream.toByteArray（）
缓冲区太大。您将在
之后获得真正的内容，即char 0x000000

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<dirStruct>
<file modified="1398855221782" name="sharedFolder\hey.txt"/>

是141个字节，至少有4859个字节的0x00000000。
如果你从字节中生成一个字符串并打印出来，你会得到什么？@EvanKnowles，客户端版本的绝对副本。我想你已经回答了你自己的问题。代码不是问题所在，而是从客户端发送到服务器的数据。您的问题没有解释如何发送/接收数据。听起来好像插入了一些字符（可能是空格）。您最初是如何从字符串转换为字节[]的？这可能是编码问题吗？原始文件是否在Windows计算机中创建并发送到Linux计算机？
