The XMLPath of the value you want to retrieve. The path must correspond to a single entry in the XML, thus is not a complete

XPath with regular expressions and variables.

Code Sample

The following gets the number of items in an invoice, loops through each item and displays the item's description with show().

define(&i, integer, 0)

define(&currentItemDescription, string, '')

define(&numberOfItems, integer, xmlcount('/MyData/CUSTOMER/INVOICES/INVOICE/ITEM'))

for(&i, 1, 1, &numberOfItems)

&currentItemDescription := xmlget('-

/MyData/CUSTOMER/INVOICES/INVOICE/ITEM['+inttostr(&i)+']/Description')

show(&currentItemDescription)

crlf()

endfor()

Measure

Add (function)

Adds two numerical expressions. This is the functional equivalent to the + operator, when you use the + operator with numer-

ical expressions.

Syntax

add( expression, expression2 ) integer, measure, currency value

Arguments

expression1, expression2

Integer, measure, or currency values. Both expressions must be the same type. The returned value is set according to the

type of the parameters.

Code Sample Examples

Examples 1 and 2 show both ways of adding numbers.

Example 1

show(inttostr(2+2)) %Displays 4

Example 2

show(floattostr(add(4.7,2.1))) %Displays 6.8
