[英]C# '&' regex problem
i've got a problem with C# regular expression. 我对C#正则表达式有疑问。 There is an JSON string like this (it's from Google Insights page): 有一个这样的JSON字符串(来自Google Insights页面):
{"name":"all categories","id":0,"prime":true,"children":[{"name":"arts \& humanities","id":570,"prime":true,"children":[{"name":"books \& literature","id":22, ...
Now I want to write a regex to find, for example, books \& literature
-- but I can't. 现在,我想编写一个正则表达式来查找books \& literature
,例如books \& literature
-但我找不到。 Neither Regex.Match(html, "books & literature", RegexOptions.IgnoreCase)
nor Regex.Match(html, "books \\\& literature", RegexOptions.IgnoreCase)
doesn't works. Regex.Match(html, "books & literature", RegexOptions.IgnoreCase)
或Regex.Match(html, "books \\\& literature", RegexOptions.IgnoreCase)
无效。 What am I doing wrong? 我究竟做错了什么?
Since the string you're searching for has a literal \\
, you need to have a literal backslash escaped in your regex, either by @"books \\\& literature"
or "books \\\\\\\& literature"
. 由于您要搜索的字符串具有文字\\
,因此您需要在正则表达式中转义文字反斜杠,可以使用@"books \\\& literature"
或"books \\\\\\\& literature"
转义。
For example: 例如:
Regex.Match(html, @"books \\u0026 literature", RegexOptions.IgnoreCase)
