本文解释了Microsoft.XMLDOM中xml属性返回的XML字符串没有encoding属性的原因，仅在使用save方法时才会保留原始编码格式。

根据微软的说明，Microsoft.XMLDOM xml属性取出的XML串是没有encoding属性的，只有save方法才有。参见微软的MSDN说明：

The property is read-only.

The xml property always returns a Unicode string. That is, the xml property for DOMDocument converts the document from its original encoding to Unicode. As a result, the original encoding attribute is removed. For example, <?xml version="1.0" encoding="UTF-8"?> appears in the xml property as follows.

other

<?xml version="1.0"?>

If the original encoding was not removed by the xml property, the following line returns an error indicating the parser cannot switch from Unicode to UTF-8 encoding.

other

xmlDoc.loadxml(xmlDoc.xml);

If you use the save method, the original encoding is preserved. For example, if you load a document in Microsoft® Windows® 1252 encoding, it will be saved in that format.

This value depends on the value of the nodeType property.
