我要取的是：1楼. 晚安啊 各位，上面文本的红色字体，
文本_取出中间文本 (返回文本, “class=” ＋ #引号 ＋ “txt-big” ＋ #引号 ＋ “>”, “492133032”)
这样会把前面的也全部取出来了，有啥办法能只取我要的不？右边文本是指定的这个：492133032

Arbitrary

用正则,so easy

文本_取出中间文本 (返回文本, “class=” ＋ #引号 ＋ “txt-big” ＋ #引号 ＋ “>”, “</span>”)

文本_取出中间文本 (返回文本, “class=” ＋ #引号 ＋ “txt-big” ＋ #引号 ＋ “>”, “”)

返回文本=文本_取出中间文本 (返回文本, “class=” ＋ #引号 ＋ “txt-big” ＋ #引号 ＋ “>”, “492133032”)
返回文本=文本_取出中间文本("前"+返回文本,"前","</span>")

笨人笨办法，多取一次。
