我需要快速帮助来解决一个棘手的问题，这个问题简直让我发疯。

String example = "<digitalObject>" +
                 "<title>title</title>" +
                 "<creator>Name</creator>" +
                 "<location>link</location>"+
                 "<relatedAsset>related realife object</relatedAsset>" +
                 "<note><src lang =\"en\">value</src></note>" +
                 "<archivalDate>date</archivalDate>"+
                 "<mimeFormat>mime type</mimeFormat>"+
                 "<digitalObjectOwner>owner</digitalObjectOwner>"+
                 "</digitalObject>";

String example4="<digitalObject>" + 
                "<title>title</title>"+
                "<creator>name</creator>"+ 
                "<location>link</location>"+
                "<relatedAsset>related realife object</relatedAsset>" + 
                "<note><src lang=\"en\">value</src></note>" + 
                "<archivialDate>date</archivialDate>"+
                "<mimeFormat>mime type</mimeFormat>" + 
                "<digitalObjectOwner>owner</digitalObjectOwner>" + 
                "</digitalObject>";

以下代码获取 w3c.dom.Document 对象

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
Document doc=null;
try {
builder = factory.newDocumentBuilder();

InputSource is = new InputSource();
is.setCharacterStream(new StringReader(example4));
doc = builder.parse(is);
    } catch (SAXException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    }

    return doc;
}

第一个字符串（example）被正确解析，第二个字符串（example2）返回 null。

知道为什么吗？我真的看不出两者之间有什么区别！

提前致谢，我确信这是如此愚蠢的事情，我会感到羞愧...

编辑：实际上字符串中的内容相同，但仍然有 2 个不同的结果... 我会尝试区分它们...

I need a quick help for a tricky problem that is literally driving me crazy.

String example = "<digitalObject>" +
                 "<title>title</title>" +
                 "<creator>Name</creator>" +
                 "<location>link</location>"+
                 "<relatedAsset>related realife object</relatedAsset>" +
                 "<note><src lang =\"en\">value</src></note>" +
                 "<archivalDate>date</archivalDate>"+
                 "<mimeFormat>mime type</mimeFormat>"+
                 "<digitalObjectOwner>owner</digitalObjectOwner>"+
                 "</digitalObject>";

String example4="<digitalObject>" + 
                "<title>title</title>"+
                "<creator>name</creator>"+ 
                "<location>link</location>"+
                "<relatedAsset>related realife object</relatedAsset>" + 
                "<note><src lang=\"en\">value</src></note>" + 
                "<archivialDate>date</archivialDate>"+
                "<mimeFormat>mime type</mimeFormat>" + 
                "<digitalObjectOwner>owner</digitalObjectOwner>" + 
                "</digitalObject>";

The following code to get a w3c.dom.Document object

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
Document doc=null;
try {
builder = factory.newDocumentBuilder();

InputSource is = new InputSource();
is.setCharacterStream(new StringReader(example4));
doc = builder.parse(is);
    } catch (SAXException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    }

    return doc;
}

The first string (example) is parsed correctly, the second one (example2) returns null.

Any idea why? I can't really see any difference between the 2!!

Thanks in advance I'm sure it's something so dumb I will feel ashamed...

EDIT: actually with the same content in the string, still 2 different outcome...
I'll try to diff them...
