About Filter
Filter is a new developed function based on mass-rep technology in Ultra Replacer by rep files. Rep file is a file composed of lines of rep commands which will carry a series of replacement. Via this technology, we analyzed source code of some web site, and grasp the structure and keywords of this website, wrote rep commands to do structural cleaning to eradicate advertising, banner, and footer, all useless part in a downloaded web page.
Here's the screenshot of the filter tab in option panel.

Local Example

(now you can preview the page before cleaning) and checkup the box of 'use filter' and select the filter of 'ebay', press 'OK' on option panel, and press 'clean' button, needn't save, press preview to see the result.

Problems
The problem of filter is it's quantity and period. First, there are too many websites with different code structure, a filter is only for some kind of pages for a website, so we can only provide filters for some main websites, and will add new rep files step by step. So we hope you, each end-user can write rep file on your demand for your downloaded pages (please see the details of rep commands). Second, the structure of a website will change instantly, then the rep file will no work. So we have to update them when they changed, we also hope you can tell me if the rep file expired.
Altogether, with filters, we can say HTML Page Cleaner is a real cleaner.
