LR mobile HTTP/HTML协议实战

 下面我们来看一下手动关联后的脚本情况：

最好不要用自动关联，虽然LR11.5已经准确了不少，但还是会出现截取不准确的情况。

因为当时区域没有修改，导致中间有些问号，其实中间部分主要是一些地方区的中文名称。

可以看出都还是比较有规律的。可用的几个函数都在以上列出，其中LR11.5中最新加的一个函数regexp最大的特点是可以用正则表达式，但我还是习惯用web_reg_save_param_ex ，因为LB/IC 和RB/IC可以来根据边界匹配，二者在实际中运用可能还是会有差别，可能会出现有些情况只能用其中一种才能解决的问题，之前在做上面的时候就曾遇到过用正则表达式匹配出的值会多一些。像上面返回中有还有一行

<SPAN style="FONT-FAMILY: 'Microsoft YaHei',微软雅黑,SimHei,tahoma,arial,helvetica,sans-serif"><div align="center"><a href="#" class="c">?????????</a></div></SPAN>

<div align="center"><a href="#" class="c">?????????</a></div>

如果用正则表达式就很难区分以上标签中的内容与实际要参数化的内容了。当然这里还是可以的，因为中文长度不一致，可能通过正则表达式限制长度解决，但如果长度也与要获取的参数相同又该怎处理呢？

因为获取上面的参数可以用如下关联函数解决

<SPAN style="FONT-FAMILY: 'Microsoft YaHei',微软雅黑,SimHei,tahoma,arial,helvetica,sans-serif"> web_reg_save_param_regexp(
"paramName=DistrictsName",
"RegExp=class=\"c\">(.{4,8})</a>\r\n", /*match Chinese character use ([\u4e00-\u9fa5]{4,6}).. because chinese character display inproper here */
"Ordinal=all",
LAST);
'这里通过限制长度还是能够正确获取的'</SPAN>
