Where would you get that he is asking someone to write a script for him?! @Champak has been a contributor to the forum for some time, and is asking precisely that: for help ideas to better his (very obviously already written) script. Please refrain from stepping into a post if you have nothing of value to add.

No where did I say write my code. I have my code. If you don't want to help, pass on. I said "I" need to make it better. Whether you're helpful and provide the whole code, a portion, example, or tell me what is slowing it down is fine, but don't try to play me and tell me what the forum is for.

 

Edit:

I see you addressed it at the same time JLogan3o13

@JLogan3o13 Yeah i am not a moderator. This is somthing i know already.  (it s my second warning about similare note)

But if we translate corectly :

"Can someone make this better"  it s not a translation error even with my bad english.

No one gonna make a script better for someone else are we true about that ? Well i dont want to polish the topic.

@Champak Apologise then.

 

Edit :

Google translation :

My goal is to get things done 

Nothing about rage :P

So if it is your second warning, perhaps engage your brain before your typing fingers in the future ;)

I will post here few examples, stay watching (when I done I say that)

Another approach:
Since it seems that the loading of that web page into the browser takes a good part of the total time needed to accomplish your task,
I would suggest to download only the html code of the page so to avoid the waste of time spent by the browser to render images and advertisements, and then take data from the table.
What you need is a table extractor from raw html code, and you can find it here:

Here is an example (with the above udf already embedded at the bottom of the listing), seems quite faster than your way.
Also, in this example the extracted table is as is on the web page, up to you to "clean" and tidy it and take only wanted columns from the returned array.

; #include <_HtmlTable2Array.au3> ; <--- udf already included (hard coded) at bottom of this demo
#include <array.au3> ; only for _arrayDisplay()

Local $sPageSource = BinaryToString(InetRead("http://www.newyorkgasprices.com/GasPriceSearch.aspx?typ=adv&fuel=A&srch=1&state=TX&area=Dallas+-+North&area=Dallas+-+NW&area=Dallas+-+SE&area=Dallas+-+South&area=Dallas+-+SW&area=Dallas+-+West&site=NewYork,Dallas&station=Chevron&tme_limit=24", 1))

You might parse the source code using regex. Maybe hazardous but certainly much faster ...

Can someone make this better please? I need to speed it up and be a little more efficient. 

I hope this is what you requested, as currently you are using much less FOR IN LOOP so the number of iteration is could rapidly decrased, and much more HTML Code is parsed by DOM which mean in MS AcitveX component >> in Native C++ (i think so).

Thanks to all. Chimp, you are exactly right in the page loading taking most of the time, I just never knew there was a way around it. Your example is simple to understand and easy to duplicate elsewhere, I'm going to keep it as a quick go to for other more complicated tables when I need a quick remedy. Mikell, all I can say is bloody brilliant...in an english accent of course. I ran that code 6 times because I simply didn't believe it...I dont understand it right now, but I'm starting to believe it:D. I made a different script based on another gas station that changed up their website a while back, and because it took so long, a lot of times I never used it, especially with the connection speed in my car. Bet I'll always be using it now. There are a bunch of other IE codes I'm going to redo now with this new method. This should improve my overall app with the other parts when I'm done.

Thanks again all.

Spoke too soon. As much as I love mikell's and as fast as it is, it's not universal. It fails in all other station/city/state searches...like it was crafted specifically for this search. I'm going to have to dive into it when I have time and see what makes it tick to make it universal. For now, with some changes to chimp's example, that's the route I'll be going.

Exactly why many insist that regexp should NOT be used as an HTML parser.

P.S. See this for an amusing regexp rant.

..reason why I mentioned 'for the fun' , and called this 'hazardous' in post #11  ;) It will never be an universal way
As Champak noticed a tiny change in the source code can cause the whole thing to fail

But... it's sooo fast :drool:
I had no time enough to try other expressions and check the reliability but a regex way is (maybe) possible for this particular case - with the usual reservations of course !

In one of my script I use a REGEXP with about 20 frequently changing HTML elements, which are sometimes contain tables, so at least 4 times a year I have to modify REGEXP. Throughout the expression, I'm collecting 40 information, Some of them need further work (parsing).

You can ask me: So why I'm using RegExp ?
If I parse differently, and so I would have to change the script a few times a year, and besides, I agree with the following statement:

Yes... IMHO I don't believe that we should systematically ban a method because of this of because of that
Anyway a regex-based code is NOT a html parser BUT a text parser - which could sometimes work nice  :)

So. Another try. Looks much better, obviously I couldn't test the whole site but I did some random tests sucessfully - and it's still extremely fast
Waiting now for Champak's feedback  :D

Edit
unexpected error in the source code on last try => fix  :sweating:
