我想在lg节点和（马来西亚，缅甸）的mc节点中提取（AFC U-22锦标赛资格赛）文本。这可能吗？

Answer 1

你必须做一些字符串操作和搜索

例如，你可以搜索锦标赛（锦标赛冠军，“）和第一次出现之间的字符串;）;

对于马来西亚和缅甸使用类似的搜索方法，没有内置函数可以解析这种字符串

如果您可以控制此请求，请考虑使用JSON或XML作为远程数据

Answer 2

你需要在此进行字符串搜索。这个link将帮助你实现这一目标。您可以按照以下步骤操作。

在您从连接中收到的文字数据中搜索“lg（”。
然后搜索逗号“，”的第二次出现，并从下一个位置提取所有字符，直到它没有得到双引号“”“。
然后移动索引并在文本中搜索“mc（”。
现在搜索逗号“，”的第7个外观，并从下一个位置提取所有字符，直到它没有得到双引号“”“。

现在你可以得到两个字符串。

祝你好运
