Question : How do I modify an XML file from Access VBA
|
|
I have file with a "qsp" extension (I changed it to txt so I could attach it) that is used by another application and the file appears to be an XML file (testjorge.txt attached). I need to replace specific text "ListValues=One\,Two\,Three\,Four\,five\,six\,seven" from the file with values from a table. Example the "ListValues=" statement would list the values from the table instead of the "One\,Two\,Three\,Four\,five\,six\,seven". The file will be updated regularly so it needs to be handled maybe in VBA? Any help would be greatly appriciated.

i'd do it by using VBA to open a new file for input, and read in the lines from your file, testing for dataline = "ListValues=One\,Two\,Three\,Four\,five\,six\,seven,", then manufacture and output the new line, then continue reading the lines from the course document, to make a new file...
a loop to pick up the values from the table and concetenate them into a string would not be too tricky.
this could all be done using fancy recordsets, or more lazily, from a form with a combo box controlling the data.
The attached MDB has a form which takes the path to the xml file, has a combo picking up the records id, xvalue, where xvalue column is the actual new values to insert, from table1.
the test output is created as filename_out.xml, but i had to rename it txt to upload it here.
the code from the form is below.
