On Dec 1, 2013, user Sammi De Guzman asked on StackOverflow:
How do I declare attributes common to multiple elements?
I have multiple elements I want to give these attributes:
Is this possible somehow in DTD, or will I have to do it manually?
(Also, while I\’m here, I don\’t think it was such a good idea to declare the
paddingattributes that way. Does anyone know a better way?)
4.5h later, Daniel Haley answered (the answer is now the accepted answer):
Here\’s another example that has a mix of the parameter entity references along with attributes that only appear on the individual elements.
However, making a minimal-example file
exampl.xml out of
these, we get the following results from
xmmlint, Chromium, and
exampl.xml:12: parser error : ATTLIST: no name for Attribute <!ATTLIST elem1 %attrs;> ^ exampl.xml:12: parser error : internal error: xmlParseInternalSubset: error detected in Markup declaration <!ATTLIST elem1 %attrs;> ^ Entity: line 1: width CDATA "0" ^ exampl.xml:12: parser error : internal error: xmlParseInternalSubset: error detected in Markup declaration <!ATTLIST elem1 %attrs;> ^ exampl.xml:14: parser error : StartTag: invalid element name <!ELEMENT elem2 (#PCDATA)> ^ exampl.xml:14: parser error : Extra content at the end of the document <!ELEMENT elem2 (#PCDATA)> ^
error on line 12 at column 17: ATTLIST: no name for Attribute
XML Parsing Error: illegal parameter entity reference Location: file:///path/exampl.xml Line Number 12, Column 17:
So, can we really use that? Is that answer correct? What can we use that method in? I guess not in much.
