[英]Java regex to match a pattern
I am new to Java. 我是Java新手。 Please help me with a Java regex to match a pattern and retrieve the value.
请帮我使用Java正则表达式匹配模式并检索值。 I need to match the pattern bellow:
我需要匹配下面的模式:
\# someproperty=somevalue // this is a new property
\#someproperty=somevalue // this is a new property
I have to match the above patterns (which may contains spaces) and I need to retrieve "someproperty"
and "somevalue"
. 我必须匹配上面的模式(可能包含空格),我需要检索
"someproperty"
和"somevalue"
。
I tried with the pattern below, but it just matches only someproperty=somevalue
, without "#"
at the beginning. 我尝试使用下面的模式,但它只匹配
someproperty=somevalue
,开头没有"#"
。 Please help me out. 请帮帮我。
Pattern propertyKeyPattern = Pattern.compile("^\\s*(\\S+?)\\s*=.*?");
If you want to match the whole string and find patterns, such as " \\# someproperty =some value
". 如果要匹配整个字符串并查找模式,例如“
\\# someproperty =some value
”。 Try regular Expression 尝试正则表达式
^\\#\s*(\S+?)\s*=(.*)$
as Java string, it is 作为Java字符串,它是
"^\\\\#\\s*(\\S+?)\\s*=(.*)$"
The match result for string \\# someproperty = a some value
is 字符串
\\# someproperty = a some value
的匹配结果\\# someproperty = a some value
是
matches() = Yes
find() = Yes
group(0) = \# someproperty = a some value
group(1) = someproperty
group(2) = a some value
String a=yourString.replaceAll("[^\\w\\s]"," "); String a = yourString.replaceAll(“[^ \\ w \\ s]”,“”); By using this you will get "someproperty" and "somevalue" string then u can check it.
通过使用它你将得到“someproperty”和“somevalue”字符串,然后你可以检查它。 For more post your question clearly.
