Re: [Help-glpk] comments in csv data files

[Nigel Galloway]

I might have mentioned the benefits of XML before. It has been helpfully 
pointed out that a program may be written in grep to convert csv to XML. 
Careful research has revealed that Excel can read csv and save it as XML.

How then to include the useful comments.

It would be possible to include the comments and then write a program in grep 
to remove them.

One of the benefits of XML is that someone may already have done this for me!!!!

You are looking to create an Excel file by selecting only some of 
the Columns from an XML. The columns are not is the correct 
sequence for the Excel so they need to be mapped.
You have an XML that contains columns A, B, C, D, E, F, etc.
You only need data from columns B, D, and F.
But in the output Excel file the sequence has to be F, B, and D.


To accomplish the task we will use XMLFox Advance that is a useful 
XML and XSD schema editor. By using XMLFox Advance you can output 
data to several other data format files. The Editor allows you 
export XML tables or whole XML to the following data files: TXT; 
upload XML into MS SQL Server database, convert into CSV (Comma 
Separated Value) file, convert into HTML page, create MS Access 
database, upload XML into SQL Server database, convert to PDF, and 
create Excel file.
