Parse data from website
I am a PowerShell newbie.... I have been struggling on how to get a date value from a website.
I need to get a date from a certain file on a webpage. The webpage is in index format so looks lie this:
8/23/2014 12:00 AM 422508 file120.abc
8/23/2014 12:00 AM 440964 file121.abc
8/23/2014 12:00 AM 332636 file122.abc
...
11/26/2017 2:30 PM 3823 thefile.ini
...
11/25/2017 1:01 AM 88044 file309.abc
I need to find the line that contains 'thefile.ini' and get the date (11/26/2017) from it
When I look at the view source on the page I see
<br>11/26/2017 2:30 PM 3823 <A HREF="/folder/thefile.ini"

Can we have an example of the webpage ?, (I mean something like the web saved into an HTML or something) because the question is to vague to be answered.
No, it is a web listing. The URL is something like (can't paste the real link here)
http://mcafee.xxx.xxxx.xxx/css_content/current/VSCANDAT1000/DAT/0000/
http://mcafee.xxx.xxxx.xxx/css_content/current/VSCANDAT1000/DAT/0000/
Well let's start for something!
Source: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/invoke-webrequest?view=powershell-5.1
$R = Invoke-WebRequest -URI http://putTheRealUrlHere.com
then do
$R.AllElements | gm
and post it here.
or
$R.AllElements | where {$_.innerhtml -like "11/26/2017"}
It's hard to tell the exact query because i don't have the link. sorry.

First one:

then do

was included, verify that the path is correct and try again.

that works on powershell version 5.1
to get the version go to a ps console and write: $PSVersionTable

If I delete the 'then do' it displays the information (if this is what you are expecting)

What's frustrating about this is when I view source the date field I need is before the actual file. Making it harder....
Well it's a web view.. there's nothing u can do about it.
Ok run this:
$R.AllElements | where {$_.innerhtml -like "11/26/2017"}
Ok run this:
$R.AllElements | where {$_.innerhtml -like "11/26/2017"}
Looks like nothing returned:
PS C:\WINDOWS\system32>
$R = Invoke-WebRequest -URI "http://mcafee.xxx.xxxx.xxx/css_content/current/VSCANDAT1000/DAT/0000/"
$R.AllElements | where {$_.innerhtml -like "11/26/2017"}
PS C:\WINDOWS\system32>

PS C:\WINDOWS\system32>
Well, the question can't be answered because of the lack of details, you can keep exploring the innerhtml and look for the properties you are looking for, or maybe if you can get the information in CSV or XML that would be helpful to your proposes.

Jose, I appreciate you trying to find a solution however not sure what you mean by 'lack of details'. I provided you everything I could.
The URL I am accessing looks like this (can't provide actual link since it is restricted)
On that listing is a filename called 'avvdat.ini'
I am trying to get the date to the left of that filename.
When I hit F12 on the webpage it shows the data as below. I put blocks around the date and the file.

I don't think that any can give you an answer with the information you have provided. What I suggest you here, it's to save the HTML file in your desktop and remove the information that is not relevant to the question, (like enterprise, number of McAfee account or whatever). and left the HTML structure intact so we can finish the answer. What I mean with incomplete or it can't be answered is that we're not wizards. We need to have the full HTML structure so we can provide an answer or do the query accordingly to your SPECIFIC NEEDS. each web page is different.
Adjust the URL in the last line, save it as Whatever.ps1, and run it.
If it gives you the date, remove the "-Debug" switch from the last line.
If it does not give you the date, open the file "McAfeeContent.html" that should be in the current folder, replace any sensitive information with placeholders, and upload it here (no screenshot - either as file attachment or inside a [code][/code] block!).
The function will parse the complete content into custom PS objects which you can either filter yourself, or you can directly pass it a filter like in the code below, so you can get information about any file listed.
The Date property returned will be a full DateTime object, not just a string.

$Content = Invoke-WebRequest -Uri $Url | Select-Object -ExpandProperty Content
If ($Debug) {$Content | Set-Content -Path "$((Get-Location -PSProvider FileSystem).Path)\McAfeeContent.html"}
$Content.Replace("`r`n", ' ') -replace '\s+', ' ' -split '<br>' |
Where-Object {$_ -match '\s*(?<Date>.*?)\s*(?<Size>\d+?)\s*<A\s+HREF\s*=\s*"(?<Path>.*?)"\s*>\s*(?<Name>.*?)</A>'} |

@{n='Date'; e={[DateTime]::ParseExact($Matches['Date'], $DTFormat, $DTProvider)}},

}
