400 Server Formats

One example might be to create a new currency format. Essentially, all currency formatting

consists of converting a number to a string, inserting commas and decimal points, and

inserting a currency symbol, such as a dollar ($) sign. The Currency format data type collects

all the common parameters and prompts you for the required values.

How data formatting works

All format files reside in the Configuration/ServerFormats/currentServerModel folder. Each

subfolder contains one XML file and multiple HTML files.

The Formats.xml file describes all the choices in the Format menu. Dreamweaver

automatically adds the Edit Format List and None options.

The folder also contains one HTML file for each currently installed format type, which

includes

AlphaCase, Currency, DateTime, Math, Number, Percent, Simple, and Trim.

The Formats.xml file

The Formats.xml file contains one format tag for each item in the Format menu. Each

format tag contains the following mandatory attributes:

■ The file=fileName attribute is the HTML file for this format type, such as "Currency".

■ The title=string attribute is the string that appears in the Format menu, such as

"Currency - default".

■ The expression=regexp attribute is a regular expression that matches the dynamic data

objects that use this format. The expression determines what format is currently applied to

a dynamic data object. For example, the expression for the

"Currency - default"

format is

"<%\s*=\s*FormatCurrency\(.*, -1, -2, -2, -

2\)\s*%>|<%\s*=\s*DoCurrency$.*, -1, -2, -2, -2$\s*%>"

. The value of the

expression attribute must be unique among all

format tags in the file; it must be specific

enough to guarantee that only instances of this format match the expression.

■ The visibility=[hidden | visible] attribute indicates whether the value appears in

the Format menu. If the value of the

visibility attribute is hidden, the format does not

appear in the Format menu.

The

format tag can contain additional, arbitrarily named attributes.

Some data formatting functions require an argument,

format, which is a JavaScript object.

This object is the node that corresponds to the

format tag in the Formats.xml file. The object

has a JavaScript property for each attribute of the corresponding

format tag.
