revXMLSetAttribute

Type

command

Summary

Creates an attribute of a node, or sets the value of an existing attribute.

Syntax

revXMLSetAttribute <treeID>, <node>, <attributeName>, <newValue>

Description

Use the revXMLSetAttribute command to create and change attributes.

If the attributeName is not already an attribute of the node, a new attribute with the specified name and value is created.

If the attribute already exists, its value is set to the newValue.

tip

To put Unicode text into an attribute, first use the uniDecode function to encode the text as UTF-8:

    revXMLSetAttribute myTree,the nodeName of me, \
          uniDecode(the unicodeText of it,\"UTF8\")

Important

The revXMLSetAttribute command is part of the XML library. To ensure that the command works in a standalone application, you must include this custom library when you create your standalone. In the Inclusions pane of the Standalone Application Settings window, make sure the "XML" checkbox is checked.

treeID		The number returned by the revXMLCreateTree or revXMLCreateTreeFromFile function when you created the XML tree.
