通过多个主机 XML 文件搜索字符串
原标题：Search through multiple hosted XML files for a string
I m working on a website that uses a lot of XML-files as data (150 in total and probably growing). Each page is an XML-file.
What I m looking for is a way to look for a string through the XML-files. I m not sure what programming language to use for this XML search engine.
I m familiar with PHP, JavaScript, JQuery. So I d prefer using those languages.
Thanks a bunch!
UPDATE: I m looking for a solution that works quickly.
Ideally, the function returns the tagname that contains the searchstring. If, for instance, the XML is as follows:
This is a great story.
If one would search for story , it would return article-1 . I m not quite sure on how to do this with a regular expression.

PHP can do this. Here s an example:
foreach(glob("{foldera/*.xml,folderb/*.xml}",GLOB_BRACE) as $filename) {
$xml = simplexml_load_file($filename);
//use regular expressions to find your string
}
You simply iterate through each file on your server using glob() with a foreach loop.

Sounds like a problem that could be solved with grep and regular expressions. Without knowing what string you re looking for it s not possible to say exactly what you should do, but reading some documentation on grep should get you started down the right path.
