Hi I have the following text:
file:/home/dx/reader/validation-garage/IDON/test-test-test@2016-10-04.txt#/
I need to retrieve test-test-test@2016-10-04.txt#
from the string above. If I can also exclude the hash even better.
I\'ve tried looking at examples like this Regex to find text between second and third slashes but having trouble getting it working, can anyone help?
I\'m using PHP regex to do this.
You may try regex expression below
\\/([a-z\\-]*\\@[0-9\\-\\.]*[a-z]{3}\\#)\\/
A working example is here: https://www.regex101.com/r/RYsh7H/1
Explanation:
[a-z\\-]* => Matches test-test-test part with lowercase and can contain dahses\\@ => Matches constant @ sign
[0-9\\-\\.]* => Matches the file name with digits, dashes and {dot}
[a-z]{3}\\# => Matches your 3 letter extension and #
PS: If you really do not need # you do not have to use regex. And you may consider using parse_url method of PHP.
Hope this helps;
Without regex you can do:
$url_parts = parse_url(\'file:/home/dx/reader/validation-garage/IDON/test-test-test@2016-10-04.txt#/\');echo end(explode(\'/\', $url_parts[\'path\']));
or better:
$url_path = parse_url(\'file:/home/dx/reader/validation-garage/IDON/test-test-test@2016-10-04.txt#/\', PHP_URL_PATH);echo end(explode(\'/\', $url_path));
basename()
also works, so you can also do like this:
echo basename(\'file:/home/dx/reader/validation-garage/IDON/test-test-test@2016-10-04.txt#/\');
公式名称:RegexString(Text,Rule,Advance,Index)
用途说明:在Excel表格或WPS表格中,使用正在表达式公式RegexString(Text,Rule,Advance,Inde)从一段文本中提取需要的字符(数据)。
参数说明:参数Text指原始文本;Rule指正则表达式匹配规则,这里使用的是C#.NET支持的正则表达式规则;Advance指是否是高级模式,0表示默认,1表示使用高级模式,即直接输入正则表达式;Index指当匹配结果多个时按顺序返回给定序号(索引)的值,默认为0,表示返回全部,填N表示返回结果中第N个值,如果N大于结果中的数量,则返回最后一个值。
数据来源:本地
运行环境:Excel2007及以上,WPS2019及以上
如下图所示,书写公式=RegexString($H$2,"value=\\""([A-Z]+)\\"">([\\u4e00-\\u9fa5]{1,})",1,G3)从单元格H2中查找币种代码。单元格H2的内容是一段网页源代码,规律是“value="币种代码">币种名称”。
