Helium Scraper Review

Helium Scraper is a visual data extracting tool standing in line with other web scraping software. This data extractor uses a search algorithm for scraping which associates the elements to be extracted by their HTML properties. This differs from the general extraction methods for web scrapers. This feature works well in cases in which the association between elements is small. For example, if you want to scrape the search engine results it’s not easy to get the needed info from them using only XPath or Regexes. This scraper facilitates extraction and manipulation of more complex information with the aid of JavaScript and SQL scripts. It’s exceptionally good for visual inner join multi-level data structures.
