java正则表达式替换html中除标签外的关键字内容_随笔

\b{keywords}\b(?=[^<>]*<)

把上面{keywords}替换成你的关键字，注意把{}也替换掉，我是为了让你看明白换哪才加的{}。

然后你找到匹配上面的正则的地方后替换成你想替换的字符串就好了，全部替换记得用全局修饰符

<head>

var G=document.getElementById

function window_load(){

var strHTML = ""// document.body.innerHTML

strHTML += "<html>"

strHTML += " <head>"

strHTML += " </head>"

strHTML += " <body>"

strHTML += " test1 "

strHTML += " test2 "

strHTML += " test3 "

strHTML += " "

strHTML += " </body>"

strHTML += "</html>"

var reg = /<(font)\s*[^<>]*>[^<>]*<\/\1\s*>/ig

var aryResult = strHTML.match(reg)

alert("用match方法匹配 ,结果:\n\n" + aryResult.join("\n"))

}

</script>

</head>

<body onload="window_load()"> \

<!--

test1

test2

test3

-->

</body>

</html>
