kandi X-RAY | html-agility-pack Summary
It is an agile HTML parser that builds a read/write DOM and supports plain XPATH or XSLT (No need to understand XPATH nor XSLT to use it, don't worry...). It is a .NET code library that allows you to parse "out of the web" HTML files. The parser is very tolerant of "real world" malformed HTML. The object model is very similar to what proposes System.Xml, but for HTML documents (or streams).

QUESTION
I'm writing code to crawl links on a given web page. I'm trying out HtmlAgilityPack to read the html contents (using www.google.co.uk in my example). The code I'm using is as follows:
...ANSWER
Answered 2021-Apr-09 at 07:27Unless your HTML is huge and has a multitude of links, I wouldn't be that worried about optimizing for performance here.
It sounds like the main problem is just finding a replacement for Contains in the Where clause. I would use a Regex for that. You can build the match pattern once, at the beginning of your method, and then use IsMatch inside the Where, like so:
QUESTION
Using Html Agility Pack, I have to scrape the innerText from all //dd tags which are set between //h2 tags (in this case between h2 tags named "Applicant" and "Agent"). How can this be done?
The following is just a piece of HTML code from which I have to scrape data:
...ANSWER
Answered 2021-Jan-12 at 18:13You can do this entirely with XPath queries as follows. You already have XPath queries to select your start and end h2 nodes. Then you can select all dd nodes between pairs of them as follows:
QUESTION
I need to replace a text match inside a HTML Tag (not the HTML Content) with asterisks. This HTML Tag might also be nested. For example:
Lorem ipsum
The result should be:
Lorem ipsum
Or for nested ones:
Loremipsum
The result should be:
Loremipsum
I've created a method for that, but it works only for unnested HTML Tags:
...ANSWER
Answered 2020-Sep-30 at 08:02You can use the following regex to match text between =' and '> then replace it with asterisks.
QUESTION
Given the snippet of html and code bellow if you know part of the src e.g. 'FileName' how do you get the post ID of the parent div this could be higher up the dom tree and there could be 0, 1 or many src's with the same 'FileName'
I'm after "postId_19701770"
I've attempted to follow this page and this page I get Error CS1061 'HtmlNodeCollection' does not contain a definition for 'ParentNode'
...ANSWER
Answered 2020-Jun-29 at 19:55Reason your code is not working is because you are looking up a ParentNode of a collection of nodes. You need to select a single node and then look up its parent.
You can search all the nodes (collection) by src as well that contains the data you are looking for. Once you have the collection, you can search each of those nodes to see which one you need or select the First() one from that collection to get its Parent.
QUESTION
I am trying to make web scrapper in C# for NSE. The code works with other sites but when ran on https://www.nseindia.com/ it gives error - An error occurred while sending the request. Unable to read data from the transport connection: Operation timed out.
I have tried with two different approaches Try1() & Try2(). Can anyone please tell what I am missing in my code?
...ANSWER
Answered 2020-Jun-24 at 04:21Your are lack of headers towards Accept and others so it couldn't response back.
Besides that, I would recommend you using HttpClient instead of HttpWebRequest
QUESTION
I've created a script in python using requests module and BeautifulSoup library to scrape the title of different posts from their inner pages traversing multiple pages using next page button. To be clearer - the script parses the links from such pages and scrape the title from such inner page.
I've created session once within main function and reuse the same without passing it in different functions (I don't know if this is an ideal way).
...ANSWER
Answered 2020-Jun-23 at 15:51Your code relies on Python scoping rules. In your functions, it searches the name s
- in local scope, and fails then
- in enclosing function, which is not the case for your code
- in global scope and succeeds
- in builtin names
Since you don't have any other session, I think it is okay to be implicit in your case.
How can I pass session explicitly within different functions keeping the existing design as is?
