XSLT has the following five predefined entities:

If you use other character entities in an XSL file, you need to define them in the DTD section of the XSL file.
Dreamweaver provides several default entity definitions that you can see at the top of an XSL file created in
Dreamweaver. These default entities cover a broad selection of the most commonly used characters.

When you preview your XSL file in a browser, Dreamweaver checks the XSL file for undefined entities and notifies
you if an undefined entity is found.

If you preview an XML file attached to an XSLT file or if you preview a server-side page with an XSLT transfor-
mation, the server or browser (instead of Dreamweaver) notifies you of an undefined entity. The following is an
example of a message you may get in Internet Explorer when you request an XML file transformed by an XSL file
with a missing entity definition:

Reference to undefined entity 'auml'. Error processing resource

'http://localhost/testthis/list.xsl'. Line 28, Position 20

ä

-------------------^

To correct the error in your page, you must add the entity definition to your page manually.

Specify a missing entity definition

1

Look up the missing character in the character entity reference page on the W3C website at

www.w3.org/TR/REC-html40/sgml/entities.html

.

This web page contains the 252 allowed entities in HTML 4 and XHTML 1.0.

For example, if the character entity Egrave is missing, search for “Egrave” on the W3C web page. You will find the
following entry:

2

Make a note of the entity name and entity code in the entry.

In the example,

Egrave

is the entity name, and

È

is the entity code.

3

With this information, switch to Code view and enter the following entity tag at the top of your XSL file (following

the Doctype declaration and with the other entity tags):

entityname "entitycode;">

In the example, you would enter the following entity tag:

4

Save your file.

If you repeatedly use the same character entities, you may want to permanently add their definitions in the XSL files
Dreamweaver creates by default when you use File > New.
