DREAMWEAVER CS3 22 Extending Dreamweaver In these examples, myJSPDocType/Description is a unique string identifier that acts as a placeholder for the localized string. The localized string is defined in the next step. 4 In the Configuration/Strings folder, create a new XML file (or edit an existing file) that defines the localized string. For example, the following code, when placed in the Configuration/Strings/strings.xml file, defines the myJSPDocType/Description string: ... ... Note: String identifiers, such as myJSPDocType/Description in the previous example, must be unique within the application. Dreamweaver, when it starts, parses all XML files within the Configuration/Strings folder and loads these unique strings. Rules for document type definition files Dreamweaver lets document types that are associated with a server model share file extensions. For example, ASPJS and ASP-VB can claim .asp as their file extension. (For information on which server model gets preference, see "canRecognizeDocument()" on page 320.) Dreamweaver does not let document types that are not associated with a server model share file extensions. If a file extension is claimed by two document types where one type is associated with a server model and the other is not, the latter document type gets preference. Suppose you have a document type called SAM, which is not associated with a server model, that has a file extension of .sam, and you add this file extension to the ASP-JS document type. When a Dreamweaver user opens a file that has a .sam extension, Dreamweaver assigns the SAM document type to it, not ASP-JS. Opening a document in Dreamweaver When a user opens a document file, Dreamweaver follows a series of steps to identify the document type based on the file's extension. If Dreamweaver successfully finds a unique document type, Dreamweaver uses that type and loads the associated server model (if any) for the document that the user is opening. If the user has selected to use Dreamweaver UltraDev 4 server behaviors, Dreamweaver loads the appropriate UltraDev 4 server model. If the file extension maps to more than one document type, Dreamweaver performs the following actions: • If a static document type is among the list of document types, it gets preference. • If all the document types are dynamic, Dreamweaver creates an alphabetical list of the server models that are associated with these document types and then calls the canRecognizeDocument() function in each server model (see "canRecognizeDocument()" on page 320). Dreamweaver collects the return values and determines which server model returned the highest valued positive integer. The document type whose server model returns the highest integer is the document type that Dreamweaver assigns to the document being opened. If, however, more than one server model returns the same integer, Dreamweaver goes through the alphabetical list of those server models, picks the first in the list, and uses that document type. For example, if both ASP-JS and ASP-VB
