MACROMEDIA FLASH MX 2004-USING ACTIONSCRIPT IN FLASH Use Manual page 280

This ActionScript creates a new LoadVars object instance, copies the values from the text fields
into the instance, and then sends the data to the server. The CFM file sends the e-mail and
returns a variable (
text field.

Save the document as sendEmail.fla, and then publish it by selecting File > Publish.

About XML
Extensible Markup Language (XML) is becoming the standard for exchanging structured data in
Internet applications. You can integrate data in Flash with servers that use XML technology to
build sophisticated applications, such as chat or brokerage systems.
In XML, as with HTML, you use tags to specify, or mark up, a body of text. In HTML, you use
predefined tags to indicate how text should appear in a web browser (for example, the
indicates that text should be bold). In XML, you define tags that identify the type of a piece of
data (for example,
information from the way it appears, so the same XML document can be used and reused in
different environments.
Every XML tag is called a node, or an element. Each node has a type (1, which indicates an XML
element, or 3, which indicates a text node), and elements might also have attributes. A node
nested in a node is called a child node. This hierarchical tree structure of nodes is called the XML
DOM—much like the JavaScript DOM, which is the structure of elements in a web browser.
In the following example,
child node
<holding>
<portfolio>
<holding symbol="rich"
qty="75"
price="245.50"
value="18412.50" />
</portfolio>
For more information on XML, see www.w3.org/XML.
