StringRegExp help! (Maybe)

4 posts in this topic

Alright, so I'm still fairly newbish to StringReg (Hence why I am doing a script using it) and I am stuck.

I successfully pulled some data from a website that I want but there's a snag on the next part.

The website I am pulling data from is Weather.com.

I am currently working on pulling the images for the days.

Here is the section I need:

<img src="http://s.imwx.com/v.20100719.135915/img/wxicon/130/26.png" alt="Cloudy" width="130" height="130"></td><!-- Column 1 -->

But the problem is, its on a new line in the script and there are a lot more <img src=" in the code.

Now, I did get it to work using a couple of other commands, but it seems like I should be able to shorten it down. If so, let me know.

Here is how I did it:

$ImageForToday = StringRegExp($sSource,'(?i)(?s)<span class="twc-forecast-when twc-none">Right Now</span>(.*?)" alt',1)
$ImageString = _ArrayToString($ImageForToday)
$ImageStringStrippedOfSpaces = StringStripWS($ImageString,8)
$ImageStringCleanedUp = StringReplace($ImageStringStrippedOfSpaces, '<imgsrc="', "")

And that would produce the correct image link.

Thanks!

What are some of the image tags that you don't want to match? Matching the one you gave is easy but the trick here will be to find something that is consistant that you can anchor to and I'm even looking at that <-- column 1 -->.

If I remembered what all of the alt= possibilities where it could also help.

Well, the only one on that page I would need help with is that one.

The other ones are unique, because they look like this:

<td class="twc-col-2 twc-forecast-icon"><a href="/weather/tenday/47130" from="today_daypartforecast_icon"><img src="http://s.imwx.com/v.20100719.135915/img/wxic/72/12.png" width="72" height="72" alt="Rain / Thunder" ></a></td><!-- Column 2 -->

I posted this just as the Forum went off-line for backup. It looks like the Column 1 bit is a viable anchor

$a_Rslt = StringRegExp($sSrc, "(?i)(?m:^)\s*<img\ssrc=.+(http.+\.png).*column 1.*-->", 1)
If NOT @Error Then
    MsgBox(0, "Result", "The image you are after should be" & @CRLF & $a_Rslt[0])
EndIf
