正则获取网页源码keyword和description ，蛋有点疼

Question

哦对了，忘了说明了，有的网页 是这样的：
<meta name=keywords content="微波炉使用高火档能耗低更节能(图),环保新知,,,微波炉,,,高火,,,节能,,,省电,,"><meta name=description content="微波炉使用高火档能耗低更节能(图)">keywords 和description没有双引号。匹配不了、希望大哥们帮我完善一下，最好测试通过

Answer 1

name在前面：<meta(\s)name=(\'|\"|)keywords(\'|\"|)(\s*)content=(\'|\"|)(.*)(\'|\"|)(\s*)>
<meta(\s)name=(\'|\"|)keywords(\'|\"|)(\s*)content=(\'|\"|)|(\'|\"|)(\s*)>
<meta(\s)name=(\'|\"|)description(\'|\"|)(\s*)content=(\'|\"|)(.*)(\'|\"|)(\s*)>
<meta(\s)name=(\'|\"|)description(\'|\"|)(\s*)content=(\'|\"|)|(\'|\"|)(\s*)>name在后面：
<meta(\s)content=(\'|\"|)(.*)(\'|\"|)(\s*)name=(\'|\"|)keywords(\'|\"|)(\s*)>
<meta(\s)content=(\'|\"|)|(\'|\"|)(\s*)name=(\'|\"|)keywords(\'|\"|)(\s*)>
<meta(\s)content=(\'|\"|)(.*)(\'|\"|)(\s*)name=(\'|\"|)description(\'|\"|)(\s*)>
<meta(\s)content=(\'|\"|)|(\'|\"|)(\s*)name=(\'|\"|)description(\'|\"|)(\s*)>

name在前面：
<meta(\s)name=(\'|\"|)keywords(\'|\"|)(\s*)content=(\'|\"|)(.*)(\'|\"|)(\s*)>
<meta(\s)name=(\'|\"|)keywords(\'|\"|)(\s*)content=(\'|\"|)|(\'|\"|)(\s*)>
<meta(\s)name=(\'|\"|)description(\'|\"|)(\s*)content=(\'|\"|)(.*)(\'|\"|)(\s*)>
<meta(\s)name=(\'|\"|)description(\'|\"|)(\s*)content=(\'|\"|)|(\'|\"|)(\s*)>name在后面：
<meta(\s)content=(\'|\"|)(.*)(\'|\"|)(\s*)name=(\'|\"|)keywords(\'|\"|)(\s*)>
<meta(\s)content=(\'|\"|)|(\'|\"|)(\s*)name=(\'|\"|)keywords(\'|\"|)(\s*)>
<meta(\s)content=(\'|\"|)(.*)(\'|\"|)(\s*)name=(\'|\"|)description(\'|\"|)(\s*)>
<meta(\s)content=(\'|\"|)|(\'|\"|)(\s*)name=(\'|\"|)description(\'|\"|)(\s*)>

Answer 5

根据楼上，进一步得出：
name在前：<(\s*)(meta|META|Meta)(\s*)(name|NAME|Name)=(\'|\"|)(keywords|KEYWORDS|Keywords)(\'|\"|)(\s*)(content|CONTENT|Content)=(\'|\"|)(.*)(\'|\"|)(\s*)><(\s*)(meta|META|Meta)(\s*)(name|NAME|Name)=(\'|\"|)(keywords|KEYWORDS|Keywords)(\'|\"|)(\s*)(content|CONTENT|Content)=(\'|\"|)|(\'|\"|)(\s*)><(\s*)(meta|META|Meta)(\s*)(name|NAME|Name)=(\'|\"|)(description|DESCRIPTION|Description)(\'|\"|)(\s*)(content|CONTENT|Content)=(\'|\"|)(.*)(\'|\"|)(\s*)><(\s*)(meta|META|Meta)(\s*)(name|NAME|Name)=(\'|\"|)(description|DESCRIPTION|Description)(\'|\"|)(\s*)(content|CONTENT|Content)=(\'|\"|)|(\'|\"|)(\s*)>name在后：<(\s*)(meta|META|Meta)(\s*)(content|CONTENT|Content)=(\'|\"|)(.*)(\'|\"|)(\s*)(name|NAME|Name)=(\'|\"|)(keywords|KEYWORDS|Keywords)(\'|\"|)(\s*)><(\s*)(meta|META|Meta)(\s*)(content|CONTENT|Content)=(\'|\"|)|(\'|\"|)(\s*)(name|NAME|Name)=(\'|\"|)(keywords|KEYWORDS|Keywords)(\'|\"|)(\s*)><(\s*)(meta|META|Meta)(\s*)(content|CONTENT|Content)=(\'|\"|)(.*)(\'|\"|)(\s*)(name|NAME|Name)=(\'|\"|)(description|DESCRIPTION|Description)(\'|\"|)(\s*)><(\s*)(meta|META|Meta)(\s*)(content|CONTENT|Content)=(\'|\"|)|(\'|\"|)(\s*)(name|NAME|Name)=(\'|\"|)(description|DESCRIPTION|Description)(\'|\"|)(\s*)>
