Question

I want to copy multiple files from a SharePoint libary to a local directory. It is possible to use Wildcards? The following code is not working. But is there a way to use the We

Answer 1

you can parse though the html of the list.

# dummy url - i've added allitems.aspx
$url = "http://mySharePoint/websites/Site/TestDocBib/allitems.aspx"
$path = "D:\temp\"
$dl_file = $path + "allitems.html"

$WebClient = New-Object System.Net.WebClient
$WebClient.UseDefaultCredentials = $true
$WebClient.DownloadFile($url, $dl_file)

once you've downloaded the file you can parse though the file - a quick google turned up that Lee Holmes had done most of it already:

the main bit you want is the regex:

$regex = “<\s*a\s*[^>]*?href\s*=\s*[`"']*([^`"'>]+)[^>]*?>” 

I very quick hack - that may (or may not) work... but the gist is there :)

$test = gc $dl_file

$t = [Regex]::Matches($test, $regex, "IgnoreCase")
$i = 0
foreach ($tt in $t) { 
    # this assumes absolute paths - you may need to add the hostname if the paths are relative
    $url = $tt.Groups[1].Value.Trim() 
    $WebClient = New-Object System.Net.WebClient
    $WebClient.UseDefaultCredentials = $true
    $WebClient.DownloadFile($url, $($path + $i + ".jpg"))
    $i = $i + 1
}
