Merge File Example (Magic xpa 4.x)

A simple example using the Merge mechanism follows:

1. Create an HTML file with the following information, and save it in a location easy to find, for example: ‘c:\in_merge.htm’:

<!$MGREPEAT>

<!$MG_number> <!$MGIF_IsEven>Even<!$MGELSE>Odd<!$MGENDIF>

<!$MGENDREPEAT>

2. Create a Magic xpa program with the following characteristics:

• Task Type: Batch

• End Task Condition: Counter(0)=10

• Evaluate Condition: After updating record

3. Create a new I/O device with the following characteristics:

• Name: ‘Merged File’. You can enter any name.

• Media: File

• Exp/Var: Location and name for the resulting file; for example: ‘c:\out_merge.txt’

4. Create a form with the following characteristics:

• Name: ‘HTML Template’. You can enter any name.

• Class: 1

• Interface Type: Merge

• HTML File: Location and name for the HTML file that you created: ‘c:\in_merge.htm’

• Tags Table: create two entries that will match the two HTML tag in our Template file:

• • Tag Name: number replace with the Expression: Counter (0)

  • Tag Name: IsEven replace with the Expression: Counter (0) MOD 2=0

5. In the Record Suffix, create a new line with the following characteristics:

• Operation: Form Output

• From: ‘HTML Template’

• I/O: ‘Merged File’

6. Save the program, check it and execute it. If you open the resulting ‘c:\out_merge.txt’ file you should see the following lines:
