错误原因：xml文档中有" "这个值，解析的时候碰到"&"会认为nbsp是转义字符，而又没有在头部定义转义字符。

解决方法1:在xml文档中将所有"&"替换成"&amp;"， 另外"<" = "&lt;" ">" = "&gt;" "'" = "&apos;" """ = "&quot;" 解决方法2:在根元素之前声明实体如下： <!DOCTYPE 根元素标签名 [ <!ENTITY nbsp " "> <!ENTITY copy "?"> <!ENTITY reg "?"> <!ENTITY trade "?"> <!ENTITY mdash "—"> <!ENTITY ldquo "“"> <!ENTITY rdquo "”"> <!ENTITY pound "￡"> <!ENTITY yen "￥"> <!ENTITY euro "
