修复Sturts2发布包中的教程文档 | #struts2 #hta #regex
在Struts2的发行包中，有一份帮助文档，位于“struts-2.1.8.1.zip\struts-2.1.8.1\docs\docs”
?
该文档包含如下一些不错的资源：
?
Tutorials? Our tutorials are designed to help you get started with the framework ASAP. We offer an all-purpose "Bootstrap" tutorial as well as specialty tutorials on portlets and database access.? Guides? Our in-depth technical guides focus on specific components of the framework, such as the Core framework, Struts Tags, and optional Extensions, as well as migrating from Struts 1 or WebWork 2.? FAQs and Cookbook? Our FAQs and Cookbook examples provide a wide range of rapid-fire "HOWTOs" in question-and-answer format.? Security Bulletins? Our security bulletins explain any security issues and their solutions? Other Resources? Books, articles, and presentations about Struts 2.?这些资源对于初学者来说，是很好的学习资料，不过这些HTML文件中包含一以http://开头的外部样式表文件，每次在打开这些HTML文档时，页面都要很久时间才能显示。
?
<LINK type="text/css" rel="stylesheet" href="http://cwiki.apache.org/confluence/download/resources/confluence.ext.code:code/shStyles.css">
?
只要去掉这句，页面就可以很快打开，不过逐个去除不太现实，作为程序员，自然要使用聪明的办法，其实网上有许多批量查找替换文件内容的软件，不过本着研究的精神，咱还是自己搞吧。
这里依然选择用HTA+JS开发，不过无论用什么语言，思路都是一样的。
?
最核心的东西当然是匹配要去掉的样式的正则表达式了：
?
var pattern = /(<LINK.+href="http:\/\/.*)|(<SCRIPT[\s\S]*<\/SCRIPT>)|((<BODY\s+)onload="init\(\)">)/igm;
?
这里我顺便把脚本和<body>标签也去掉了，因为这些脚本会导致在使用IE查看时，有安全提示，很讨厌。
?
然后就是指定一个目录，然后递归遍历之：
?
function travel(path) { log('high', 'scanning folder "' + path + '"'); var dir = fso.GetFolder(path); var folders = new Enumerator(dir.SubFolders); var files = new Enumerator(dir.Files); // travel files for (; !files.atEnd(); files.moveNext()) { var doc = files.item(); log('info', 'analyzing file "' + doc + '"'); if (isHTMLDocument(doc)) { fixTutorial(doc); } } // travel folders for (; !folders.atEnd(); folders.moveNext()) { travel(folders.item()); }}?
其次就是具体的替换操作了，先读取文件内容，替换后再重新写进去：
?
function fixTutorial(filename) { try { log('info', 'fixing file: ' + filename); var file = fso.OpenTextFile(filename, 1); var html = file.ReadAll().replace(pattern, ''); file.Close(); file = fso.OpenTextFile(filename, 2); file.Write(html); file.Close(); log('high', 'completed.'); } catch (e) { log('warn', 'failed fixing file "' + filename + '", ' + e.description); }}?完整代码：
?
