xml parameter entity

I am new to xml.

In my DTD section, I have this:

Code:

<!ENTITY % entity "Wrox Entity">

In the body section:

Code:

<book>
<title>XML</title>
<author>abc</author>
<publisher>%entity;</publisher>
</book>

Output in IE6:

Code:

<title>XML</title>
<author>abc</author>
<publisher>%entity;</publisher>
</book>

The output is incorrect where I expect:

Code:

<publisher>Wrox Entity</publisher>

What went wrong to my xml coding?

Your entity declaration should look like:

Code:

<!ENTITY myEntity "Wrox Entity">

To use it you need am ampersand (&) before and a semi-colon (;) after:

Code:

<publisher>&myEntity;</publisher>

The % sign in entities is for those that are used only within the DTD itself.

I've got it, thanks!

This time I try to create .dtd (my_external.dtd) file in Window XP. But the problem is the file can't be recognized by the OS. Visual Studio.NET seems like does not have this function (to create dtd file). What should I do?
