python正则表达式示例

我创建了一个正则表达式来查找匹配的字符串，如下所示

window.location="process.php?file=Generics/index.nsp";
location.href = "http://www.foo.com";
location.href="http://www.foo.com";
window.location = "http://www.foo.com";
window.location.href="http://www.foo.com";
location.replace ("http://www.foo.com");
location.replace( "http://www.foo.com" ) ; 
location.assign ("http://www.foo.com");
window.location= var +"process.php?file=Generics/index.nsp";
window.location.href = path + "login" + ".html";
window.location.href = path + featureId + ".html";
window.location.href = "/" + "online-banking" + ".html";
window.location.href = path + featureName +".html";
window.location.href = link.page;
window.location.href = path + link.page + ".html";'

['window.location="process.php?file=Generics/index.nsp"','location.href = "http://www.foo.com"','window.location = "http://www.foo.com"','window.location.href="http://www.foo.com"',..]

我在正则表达式测试页面中检查了这个表达式是否正常工作

然而，当我执行程序时，我无法得到正确的结果

# -*- coding: utf-8 -*-
import re

url_reg= re.compile('(location\.(href|assign|replace)|window\.location(\.href|))\s*(=|\()+.*(;|$)')

test = '123123gjh123\
2135115123\
window.location="process.php?file=Generics/index.nsp";\
location.href = "http://www.foo.com";\
location.href="http://www.foo.com";\
window.location = "http://www.foo.com";\
window.location.href="http://www.foo.com";\
location.replace ("http://www.foo.com");\
location.replace( "http://www.foo.com" ) ; \
location.assign ("http://www.foo.com");\
window.location= var +"process.php?file=Generics/index.nsp";\
window.location.href = path + "login" + ".html";\
window.location.href = path + featureId + ".html";\
window.location.href = "/" + "online-banking" + ".html";\
window.location.href = path + featureName +".html";\
window.location.href = link.page;\
window.location.href = path + link.page + ".html";'
print url_reg.findall(test)

结果:

[('window.location', '', '', '=', '')]

我想得到如下结果值

window.location="process.php?file=Generics/index.nsp";
location.href = "http://www.foo.com";
location.href="http://www.foo.com";
window.location = "http://www.foo.com";
window.location.href="http://www.foo.com";
location.replace ("http://www.foo.com");
location.replace( "http://www.foo.com" ) ; 
location.assign ("http://www.foo.com");
window.location= var +"process.php?file=Generics/index.nsp";
window.location.href = path + "login" + ".html";
window.location.href = path + featureId + ".html";
window.location.href = "/" + "online-banking" + ".html";
window.location.href = path + featureName +".html";
window.location.href = link.page;
window.location.href = path + link.page + ".html";'

['window.location="process.php?file=Generics/index.nsp"','location.href = "http://www.foo.com"','window.location = "http://www.foo.com"','window.location.href="http://www.foo.com"',..]

请给我一些建议。

这是你的目的吗？我刚刚添加了

r'

和outter parentheis

import re

url_reg= re.compile(r'((location\.(href|assign|replace)|window\.location(\.href)?)\s*(=|\()+.*(;|$))')
test = 'blahblah...'
print map(lambda x: x[0], url_reg.findall(test))

['window.location=“process.php？file=Generics/index.nsp”；location.href=”http://www.foo.com“location.href=”http://www.foo.com“window.location=”http://www.foo.com“window.location.href=”http://www.foo.com“location.replace（”http://www.foo.com“”；位置。替换（“”）http://www.foo.com“”；location.assign（“”）http://www.foo.com")；window.location=var+“process.php？file=Generics/index.nsp”；window.location.href=path+“login”+“.html”；window.location.href=path+featureId+”.html；window.location.href=“/”+“网上银行”+“.html”；window.location.href=path+featureName+“.html”；window.location.href=link.page；window.location.href=path+link.page+“.html”；']

findall

不做任何替换，它只查找与正则表达式匹配的项。。。
