XML substitution of values
Dear all,
I'm currently working on a VBA tool in which I would like to generate multiple duplicates of the same XML-files. The aim is to replace some values each time a new XML-file is created. These files serve then in a later stage to call another software programme.
However, I faced some problems with the unicode type of strings. My current code is given below.
First I'm reading the base XML-file in the DO-loop into 'sin', afterwards I search for the location of the value of the particular variables I want to change. These values are always written between double quotes, so I would like to change everything in between the double quotes.
However, the current results returns a lot of useless symbols. I'm sure there must exist a more efficient way to deal with this, anyone who could help me out?
Cheers,
M

Index2 = InStr(Index1 + 1, sin, StrConv("p0 v=", vbUnicode)) 'Search the starting index of the place where the value is specified
Index3 = InStr(Index2 + 1, sin, StrConv(Chr(34), vbUnicode)) 'Search the starting index of the place where the value is specified
Index4 = InStr(Index3 + 1, sin, StrConv(Chr(34), vbUnicode)) 'Search the ending index of the place where the value is specified
ToReplace = Mid(sin, Index3 + 2, Index4 - Index3 - 1) 'Double qoute takes to indices in unicode
sout = Left(sin, Index3 + 1) & Replace(ToReplace, ToReplace, StrConv(VarValue(i), vbUnicode)) & Right(sin, Len(sin) - (Index4 - 2))
Next i
Set fout = fs.CreateTextFile(XmlFile_OUT, True, False) 'overwrite if the file already exists and no unicode
fout.Write (sout)
fout.Close
End Sub
