使用 hpple 解析得到发表时间,比如
element = [hppleElement searchWithXPathQuery:@"//td[3]/span[2]/text()[2]"];
temp= [element objectAtIndex:0];
NSString *content = [temp content];
得到 content =" • 置顶 • 最后回复来自"
用stringByReplacingOccurrencesOfString删除"•"和" "和"最后回复来自"
得到
content = " 置顶 "
试过
" "
和
`
"   "
无效
这里前置和后置的空格改怎么继续删除
