返回 node-set 参数中按文档顺序处于第一位的节点的扩展名称本地部分。
string local-name(node-set?)
备注
扩展名称通常包括命名空间 URI（或关联的前缀）、冒号 (:) 和本地部分。 例如，b:author 是扩展名称，其中 b 是命名空间 URI 前缀，author 是本地部分。 所以，对此节点应用 local-name() 函数将返回 author。 如果节点没有扩展名称，例如 author，对此节点应用 local-name() 函数将返回原始节点名称，即 author。
如果省略了 node-set 参数，默认的节点集中唯一的成员是上下文节点。
示例
XML 文件 (data.xml)
