DTD: Non Alphanumeric Characters in enumerated attribute

[ashimehta]

Hi All,

I have to create a DTD having non alpha-numeric characters like '&', '%', '>', etc. in an enumerated attribute. For this i used ENTITIES as <!ENTITY % Pct "&#x25;"> for '%' and so on.

The XML that i have created is as follows -

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE CUSTOMER [
<!ELEMENT CUSTOMER (ELEM*)>
<!ELEMENT ELEM (#PCDATA)>

<!ENTITY % Pct "&#x25;">
<!ENTITY % gt ">">
<!ENTITY % Mix "5%Pct;10%gt;3">

<!ATTLIST ELEM
attrib (%Mix; | SampleText) #IMPLIED
>
]>

<CUSTOMER>
<ELEM attrib="SampleText"></ELEM>
<ELEM attrib="5%10>3"></ELEM>
</CUSTOMER>

---------------------------

This XML gets validated. But if i try to open it in the browser, i get an error which reads -


The XML page cannot be displayed
Parameter entities cannot be used inside markup declarations in an internal subset. Error processing resource 'file:///...Test.xml'. Line 8, Position 18

<!ENTITY % Mix "5%Pct;10%gt;3">
-----------------^


Plz. tell me what is the solution to this.


Thanks in Advance.
Ashish.
