Complete XML declaration:
The specific meaning of the attribute:
The version attribute just we mentioned that in an XML processing indication must include the version of the version attribute indicating the version number of the XML used, and it must be in the first bit in the attribute list. Since the current XML latest version is 1.0, we have seen no exception: Version = "1.0". The Standalone property This property indicates whether the XML file is used with a separate marking declaration file. Therefore, if the property is set to "YES", there is no additional DTD file to make a marking declaration. Instead, if this property is set to "NO", there may be such a file. (Note, may not.) Encoding properties The XML syntax analyzer is supported by 8-bit and 16-bit encoding criteria. However, XML may support a larger coding collection. But usually we don't use so much encoding, just know the following common encodings: Simplified Chinese code: GB2312 Traditional Chinese code: BIG5
