Rename file from content of an xml

Hello Peter,

I don't quite understand it.

I have different XML which may or may not have the tag "Positions/PurchaseOrderPositionId".

If I have the tag it should:

pinv_1010_500164_CAQS051524A-1_12TAG34.pdf
if not
pinv_1010_500164_CAQS051524A-1.pdf

But now it does:
pinv_1010_500164_CAQS051524A-1_.pdf

I don't quite understand what he is doing here:
if (FileName[Length(FileName)]='_')

Thanks for your support
Thomas

Let me double check

Underscores are rather difficult to work with in unicode word because there are several of them which look exactly the same
en.wikipedia.org/wiki/Underscore

Anyway I have found a way of dealing with missing tags just by using xslt

All you need to is to delete underscores and insert one tag 

 

 

I have attached package and XSLT for your convenience.

Hello Mike,

Works great.
Thanks for your solution.

Now they have come up with a new requirement.

I changed "Positions/PurchaseOrderPositionId" to "PurchaseOrderNum" because they want the info from the head now.
pinv_<xsl:apply-templates select="ReceiverId"/><xsl:apply-templates select="SenderAddress/Id"/><xsl:apply-templates select="InvoiceNum"/><xsl:apply-templates select="PurchaseOrderNum"/>.pdf

However, there may now be several PurchaseOrderNum in the header.
But the first one is sufficient for us.
Can I tell the xlst that it should only take the first PurchaseOrderNum?

Thank you and sorry
Thomas

This can done by adding a number EG: PurchaseOrderNum[1]
