我有一个巨大的字符串,它是由JSOUP获取到字符串中的完整html。我使用String Bufer替换API更改了html的子字符串(replace(int startIndex,int endIndex,“to be changed string)”。字符串缓冲区完全填充。但是当我尝试用新的字符串缓冲区替换html的子字符串时,它不起作用。
以下是代码段。
html = html.replace(divStyle1.trim(), heightwidthM.toString().trim());
最初的大HTML是
<!DOCTYPE html>
<html xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" class="SAF" id="global-header-light">
<head>
</head>
<body>
**<div style="background-image: url(http://aka-cdn-ns.adtech.de/rm/ads/23274/HPWomenLOFT_1381687318.jpg);background-repeat: no-repeat;-webkit-background-size: 1001px 2059px; height: 2059px; width: 1001px; text-align: center; margin: 0 auto;">**
<div style="height:2058px; padding-left:0px; padding-top:36px;">
<iframe style="height:90px; width:728px;"/>
</div>
</div>
</body>
</html>
divStyle1字符串是
background-image: url(http://aka-cdn-ns.adtech.de/rm/ads/23274/HPWomenLOFT_1381687318.jpg);background-repeat: no-repeat;-webkit-background-size: 1001px 2059px; height: 2059px; width: 1001px; text-align: center; margin: 0 auto;
String缓冲区的值为
background-image:url(http://aka-cdn-ns.adtech.de/rm/ads/23274/HPWomenLOFT_1381687318.jpg);background-repeat:no-repeat; -webkit-background-size:1001px 2059px; height:720px; width:900px; text-align:center; margin:0 auto;

使用JSoup
非常容易String html = "<!DOCTYPE html>\n<html xmlns:og=\"http://opengraphprotocol.org/schema/\" xmlns:fb=\"http://www.facebook.com/2008/fbml\" xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\" lang=\"en\" class=\"SAF\" id=\"global-header-light\">\n<head>\n\n</head>\n<body>\n\n\n**<div style=\"background-image: url(http://aka-cdn-ns.adtech.de/rm/ads/23274/HPWomenLOFT_1381687318.jpg);background-repeat: no-repeat;-webkit-background-size: 1001px 2059px; height: 2059px; width: 1001px; text-align: center; margin: 0 auto;\">** \n\n<div style=\"height:2058px; padding-left:0px; padding-top:36px;\">\n\n\n<iframe style=\"height:90px; width:728px;\"/>\n\n\n\n</div>\n</div>\n\n</body>\n</html>";
String newStyle = "background-image: url(http://aka-cdn-ns.adtech.de/rm/ads/23274/HPWomenLOFT_1381687318.jpg);background-repeat: no-repeat;-webkit-background-size: 1001px 2059px; height:720px; width:900px; text-align: center; margin: 0 auto;";
Document document = Jsoup.parse(html);
document.body().child(0).attr("style", newStyle);
System.out.println(document.html());

回到我的建议,如果你不介意尝试,你可以做这样的事情:
Document newDocument = Jsoup.parse(<your html string>, StringUtils.EMPTY, Parser.htmlParser());
Elements yourStyles = newDocument.select("div[style]"); // this will select all div with attributes style
yourStyles.get(0).attr("style", <your new value>); // this will get your first div and replace attribute style to your new value
System.out.println(newDocument.outerHtml());
