我正在尝试将gg值输入到CommercialName,我正在使用以下内容:
/Book/Location[@id = 'Amsterdam']/Author[AuthorInfo[Name = 'John'][Age = '51']]/BookInfo/CommlName/CommercialName
<Book>
<Location id="Amsterdam">
<Author>
<AuthorInfo>
<Name>John</Name>
<Age>51</Age>
</AuthorInfo>
<BookInfo>
<CommlName>
<CommercialName>gg</CommercialName>
</CommlName>
</BookInfo>
</Author>
</Location>
</Book>
