Function overview

Prototype

xmlNode ( name; required; attributes; contents )

Parameters

name Name of the node

required Should this node be created regardless of whether it has contents. If required & contents is empty it will create an empty node

attributes Space separated XML attributes in the form attributename="something". As per the XML standard

contents What should appear

Description

Tags: XML

Create an XML node. It doesn't cater for invalid XML characters in the name, attributes or contents as yet but might add it soon.

The reason you might use the required parameter is if you are referencing a field for contents & you don't need the node to exist if the field is empty.

There might also be scope for creating an xmlAttribute( name ; value ) Custom Function as well but thought it just clutters it for the moment... it might look something like this:
name & "=\"" & value & "\""

Usage would be something like
list( xmlAttribute( "validate" ; "true" ) ; xmlAttribute( "keyword" ; "please" ) )

Examples

Sample input

// No database fields example

xmlNode( "basket" ; 1 ; "validate=\"true\"" ;

xmlNode( "item" ; 1 ; "validate=\"true\"" ; "shoe" )
xmlNode( "item" ; 0 ; "validate=\"true\"" ; "" )
xmlNode( "item" ; 1 ; "validate=\"true\"" ; "" )
xmlNode( "jacket" ; 1 ; "validate=\"true\"" ; "jacket" )

)

Sample output

// Database fields example where you are in the BASKET table listing related records from the ITEMS table.

xmlNode( "basket" ; 1 ; "validate=\"true\"" ;
list( basket_ITEMS::xmlNodeCalc )
)

/* For this example table ITEMS contains fields "xmlNodeCalc"
and "item_name". "xmlNodeCalc" would evaluate to the following:
xmlNode( "item" ; 1 ; "validate=\"true\"" ; item_name )
*/

Function code

If( required or ( not ( IsEmpty( attributes ) and IsEmpty( contents ) ) ) ;

Substitute(

¶ & "<" & name & If( not IsEmpty( attributes ) ; " " ) & attributes &

If( IsEmpty( contents ) ;

" />" ;

">" & contents & If( Position( contents ; "<" ; 1 ; 1 ) > 0 ; ¶ ) & "</" & name & ">"

) ; ¶ ; "¶ " ) )
