loading QVD's in xml format within subfolders

Sat, 19 Dec 2015 16:32:15 GMT

I had a requirement in which I have to read the QVD's in folders and subfolers as XML format. Basically to find meta data information about the multiple QVD's.

As an example: -

with in C:\Applications\QVD\x1.QVD

, C:\Applications\QVD2\x2.QVD

C:\Applications\QVD3\x3.QVD

Now I want to get load all these QVD's in xml.

I have tried below code but it always give information about x3.QVD.

Set vConcatenate = ;

sub ScanFolder(Root)

for each FileExtension in 'qvd'

for each FoundFile in filelist( Root & '\*.' & FileExtension)

let vFileName = mid(vFile, index(vFile, '\', -1) + 1, 99);

QvdFields:

$(vConcatenate)

LOAD

1 as FieldCount,

'$(vFileName)' as [File Name],

FieldName as [Field Name],

BitOffset as [Bit Offset],

BitWidth as [Bit Width],

Bias as [Bias],

NoOfSymbols as [No Of Symbols],

[NumberFormat/Type] as Type,

[NumberFormat/nDec] as Dec,

[NumberFormat/UseThou] as UseThou,

'$(FoundFile)' as SourceFile

FROM [$(FoundFile)] (XmlSimple, Table is [QvdTableHeader/Fields/QvdFieldHeader]);;

Set vConcatenate = Concatenate;

next FoundFile

next FileExtension

for each SubDirectory in dirlist( Root & '\*' )

call ScanFolder(SubDirectory)

next SubDirectory

end sub

Call ScanFolder('C:\Applications') ;

Please help

Seems to work for me, your code scanned all QVD in my download folder.

Why do you think that only x3.QVD has been scanned? Have you checked the SourceFile field values?

You are using a wrong variable name here:

let vFileName = mid(vFile, index(vFile, '\', -1) + 1, 99);

So maybe this is causing your issues.

Hi swuehl,

Yes you are correct. I am using wrong variable.

I corrected it but the point is I want to load QVD's from every folder.

Example :-

C:\Applications\folder1\x1.QVD

C:\Applications\folder1\x4.QVD

C:\Applications\folder1\subfolder1\x5.QVD

, C:\Applications\folder2\x2.QVD

C:\Applications\folder3\x3.QVD

Now if I use below code it will only fetch x1 , x4 and x5 Qvd's but not x2 and x3 as they are iin different folders and are not subfolders of folder1.

How will I fetch x2 and x3 QVD.?

Set vConcatenate = ;

sub ScanFolder(Root)

for each FileExtension in 'qvd'

for each FoundFile in filelist( Root & '\*.' & FileExtension)

let vFileName = mid(FoundFile, index(FoundFile, '\', -1) + 1, 99);

QvdFields:

$(vConcatenate)

LOAD

1 as FieldCount,

'$(vFileName)' as [File Name],

FieldName as [Field Name],

BitOffset as [Bit Offset],

BitWidth as [Bit Width],

Bias as [Bias],

NoOfSymbols as [No Of Symbols],

[NumberFormat/Type] as Type,

[NumberFormat/nDec] as Dec,

[NumberFormat/UseThou] as UseThou,

'$(FoundFile)' as SourceFile

FROM [$(FoundFile)] (XmlSimple, Table is [QvdTableHeader/Fields/QvdFieldHeader]);;

Set vConcatenate = Concatenate;

next FoundFile

next FileExtension

for each SubDirectory in dirlist( Root & '\*' )

call ScanFolder(SubDirectory)

next SubDirectory

end sub

Call ScanFolder('F:\Practise Apps\Subfolder scaning\Main') ;

Not sure what your issue is, it works at my side. Are you sure you are giving the right parent folder (parent of all subfolders you want to scan) in the initial ScanFolder call?

Call ScanFolder('F:\Practise Apps\Subfolder scaning\Main') ;
