When working with an XML file, you may experience a situation where the file contains sensitive data, and your favorite XML processing tool has a problem, such as a bug. You need to provide the vendor with a sample file that causes a bug. Of course, you can't send an XML file randomly because it may be a special tag in the sample file that is causing the problem. You need a way to clear sensitive data in a

After seeing zuola, I got a wordpress Trojan script. So I clicked the connection and simply looked at the sample. The principle is relatively simple. First, determine whether the access source is a search engine spider or bot, and then determine whether a problematic iframe-the effectiveness of the Trojan depends on the content in the iframe. This short PHP script can be used completely.
