DOM SET XML ATTRIBUTE (elementRef; attrName; attrValue{; attrName2; attrValue2; ...; attrNameN; attrValueN})
| Parameter | Type | Description | |
| elementRef | String |  | XML element reference |
| attrName | String | | Attribute to set |
| attrValue | String | Value | | New attribute value |
Description
The DOM SET XML ATTRIBUTE command allows adding one or more attributes to the XML element whose reference is passed in the elementRef parameter. It also allows setting the value of each attribute defined.
Pass the attriibute to set and its value respectively in the attrName and attrValue parameters (in the form of variables, fields or literal values). You can pass as many attribute/value pairs as you want.
The attrValue parameter can be of the text type or another type (Boolean, integer, real, date or time). If you pass a value other than text, 4D handles its conversion to text, according to the following principles:
| Type | Example of converted value |
| Boolean | "true" or "false" (not translated) |
| Integer | "123456" |
| Real | "12.34" (the decimal separator is always ".") |
| Date | "2006-12-04T00:00:00Z" (RFC 3339 standard) |
| Time | "5233" (number of seconds) |
Example
In the following XML source:
<Book> <Title>The Best Seller</Title> </Book>
If the following code is executed:
vAttrName:="Font" vAttrVal:="Verdana" DOM SET XML ATTRIBUTE(vElemRef;vAttrName;vAttrVal)
We get:
<Book> <Title Font=Verdana>The Best Seller</Title> </Book>
