QUESTION
I'm reading a tutorial about using node-osmosis at this page.
Does anyone know the meaning of >
in .paginate('#navcnt table tr > td a[href]', 5)
?
I cannot find the explanation of this symbol in the document page.
What's the default selector of node-osmosis? Its github page says it supports Sizzle selectors, Slick selectors, and more.
How to know which selector I'm using now?
...ANSWER
Answered 2017-Sep-23 at 03:15It's a css selector, it means direct child.
More information: How is the "greater than" or ">" character used in CSS?
QUESTION
I am reading the links from csv and using it to scrape. I want the node-osmosis to wait between the scrapes may be after scraping 10 sites. I tried using sleep but it seems to sleep at the wrong time while a the next site is being scraped causing it to fail.
...ANSWER
Answered 2017-Jul-05 at 13:24Your problem is that node is asynchronous. Your query is going to run everything in parallel and sleep after it has done. Perhaps what you want to do is use setInterval or setTimeout. Something like this?
