　　长度一定要够不然会报错：例如

 

XML 文本 "    <Specifications>12±2</Specifications" 附近的行号 33 处出现 XML 分析错误 0xc00ce55f。
Msg 6602, Level 16, State 2, Procedure sp_xml_preparedocument, Line 1
错误说明是 'End 元素缺少 '>' 字符。'。
Msg 8179, Level 16, State 5, Line 147
找不到句柄为 0 的预定义语句。
Msg 6607, Level 16, State 3, Procedure sp_xml_removedocument, Line 1
sp_xml_removedocument: 为参数 1 提供的值无效。

　编码结构不对：例如

 

XML 文本 "    <ObjType>" 附近的行号 5 处出现 XML 分析错误 0xc00ce508。
Msg 6602, Level 16, State 2, Procedure sp_xml_preparedocument, Line 1
错误说明是 '文本内容中发现无效字符。'。
Msg 8179, Level 16, State 5, Line 147
找不到句柄为 0 的预定义语句。
Msg 6607, Level 16, State 3, Procedure sp_xml_removedocument, Line 1
sp_xml_removedocument: 为参数 1 提供的值无效。
