Working with repeated elements – Part 2
A common issue with repeating data is the requirement to refer to the items within the list by their ordinal values.
Variables
What is the difference between an XpressDox data element and a variable?
If you have come from a HotDocs background you might think that the difference between a data element and a variable is simply semantics. However, there are important differences you need to be aware of.
Using and storing variables
Here are some examples to illustrate the concept which enables the results of calculations to be stored for further use in the template, and even for future templates.
Using variables to calculate totals
XpressDox give the template author the ability to perform calculations and other operations on the values of data elements, and to store those values in variables for later use in the template. One example of this is the ability to calculate totals on repeated data elements.
Shortcuts when using variables
With effect from Version 7, there are a number of shortcuts for referring to some of the variable-handling functions. They were introduced to take away the amount of typing necessary when many variables are being
Concatenating strings
There are times when it is necessary to concatenate the values of data elements, variables and/or hard-coded strings together to form a value which is then stored in a variable. The concat function does this.
