Visual Web Ripper 2.118.4

 

We are pretty sure that there were many things that you wanted to extract from an web page but you could not do it. As one of the best solutions for this we have Visual Web Ripper that comes as a perfect and easy to use solution when you need to harvest and extract data from any page that is on the internet.

Latest version of Visual Web Ripper is available for a free download from digzip.

Now it is simple to download complete content of an web site. This software product has the ability to go through the entire web page and will allow you to collect all the information’s that can be found on an web page. This also includes the ability to get product catalogues and search results. After everything is downloaded it will be save in a XML format or as a database.

Design of the application gives user the ability to get all the data in the structured setup. Through the interface of Visual Web Ripper you can easily and fast access all the features that you need. It is now easy to create and modify projects, also you can run those projects and access entire data that you have saved.

Key features of Visual Web Ripper:
- Visual Web Ripper has a visual editor to define projects and templates. You use a mouse to click on the content you want to collect, so no coding is required.
- Visual Web Ripper can automatically walk through whole web sites and collect complete content structures such as product catalogues or search results
- Visual Web Ripper can walk through a website just as you would when using a normal Internet browser, so AJAX and other javascripts are fully supported.
- Visual Web Ripper has a fast multi-threaded data collector for web sites where AJAX is not required for data extraction.
- Visual Web Ripper can repeatedly submit forms for all possible combinations of input values in dropdown boxes, or you can supply a list of input values by yourself.
- You can supply parameter data from a database, such as form input values or URLs that should be visited.
- Visual Web Ripper can extract data from most framesets and iframes.
- A list of anonymous proxy servers can be setup to hide your IP-address and facilitate anonymous web scrapping.
- You can schedule content extraction to keep data up-to-date. The scheduler includes email notification, logging and status screens.
- Advanced selection techniques make project templates more resistant to structural changes on web pages, so a scheduled project can keep collecting data even if the structure of a webpage changes slightly.
- Email notifications can be sent out if the structure of a webpage changes so much that you must modify the scheduled project to continue extracting content from the webpage.
- Unique features allow you to extract data from web pages with an unstructured “flow” of content. Most other web data extraction tools are unable to extract data from such web pages.
- You can collect many different types of content, such as text, links, images, files, meta tags, tag attributes and many more.
- Visual Web Ripper supports AJAX and other javascripts, so now you can collect content from all these cool websites that are fully AJAX enabled.
- You can run data extraction projects from the command line.
- And much more.

Bad sleep 'dramatically' alters body

A run of poor sleep can have a potentially profound effect on the internal workings of the human body, say UK researchers.

The activity of hundreds of genes was altered when people's sleep was cut to less than six hours a day for a week.

Writing in the journal PNAS, the researchers said the results helped explain how poor sleep damaged health.

Heart disease, diabetes, obesity and poor brain function have all been linked to substandard sleep.

What missing hours in bed actually does to alter health, however, is unknown.

So researchers at the University of Surrey analysed the blood of 26 people after they had had plenty of sleep, up to 10 hours each night for a week, and compared the results with samples after a week of fewer than six hours a night.

More than 700 genes were altered by the shift. Each contains the instructions for building a protein, so those that became more active produced more proteins - changing the chemistry of the body.

Meanwhile the natural body clock was disturbed - some genes naturally wax and wane in activity through the day, but this effect was dulled by sleep deprivation.

Prof Colin Smith, from the University of Surrey, told the BBC: "There was quite a dramatic change in activity in many different kinds of genes."

Areas such as the immune system and how the body responds to damage and stress were affected.

Prof Smith added: "Clearly sleep is critical to rebuilding the body and maintaining a functional state, all kinds of damage appear to occur - hinting at what may lead to ill health.

"If we can't actually replenish and replace new cells, then that's going to lead to degenerative diseases."

He said many people may be even more sleep deprived in their daily lives than those in the study - suggesting these changes may be common.

Dr Akhilesh Reddy, a specialist in the body clock at the University of Cambridge, said the study was "interesting".

He said the key findings were the effects on inflammation and the immune system as it was possible to see a link between those effects and health problems such as diabetes.

The findings also tie into research attempting to do away with sleep, such as by finding a drug that could eliminate the effects of sleep deprivation.

Dr Reddy said: "We don't know what the switch is that causes all these changes, but theoretically if you could switch it on or off, you might be able to get away without sleep.

"But my feeling is that sleep is fundamentally important to regenerating all cells."
