Hi,

I am looking for a description of the XSLT infoset in EBNF (all syntax elements of the language XSLT; e.g. element, attribute, comment, function and so on). It should be declared in a seperated file for reading by machine, so that it is not necessary to type every definition by myself. Where can I find it?

Alternative it is possible to have the description of the XSLT-Infoset in an XML Schema, also seperated in one file. And: Does anybody know if there is a xslt-document, which transforms the EBNF into XML Schema and vice versa?

Thank you very much for your help. I need these information for my diploma thesis (development of a language-oriented XSLT-Editor).

I believe there is a schema for XSLT version 2.0 but it is not complete, I'm not sure which way, whether it doesn't allow some obscure valid cases or lets through some failing ones.


http://www.w3.org/2005/02/schema-for-xslt20.xsd

I doubt if there's a DTD available but as I found the above with a four word google search you never know.

I also doubt if it's possible to turn EBNF to XML schema and vice versa in all cases as there are elements that are not present both languages.

You might find that xml-dev is a better place for this question. Or try contacting Richard Tobin directly.

I think Joe read the question better than I did. I went off at a tangent because of the word "infoset".

Yes, there is a schema published for XSLT. Of course, it doesn't perform complete validation - for example it doesn't check that the content of a select attribute is a valid XPath expression, or that variable references relate to a declared variable. But it's probably good enough for syntax-directed editing.

Hi,
at first, thank you very much for your support and help. But unfortunately I described my problem not clear enough.

I am not looking for a summarize of every XSLT-element (like in the above xsd-file) . I am looking for rules to build the syntax-elements of the language itself (element, attribute, comment; all itself and the same like in XML plus XSLT-specific syntax-elements like function). I am looking for a description or the rules to build that by machine. For example there is a simple description of the syntax of an XSLT-element by words:

- starttag starts with < and ends with >
- can have attributes
- needs an endtag that begins with </
...

And know I am looking for that description transformed in EBNF or XML-Schema. I have information that the XML-Specification is written partly in the EBNF-notation for describing the XML-Information Set (Infoset). I have found such a description as RDF-Schema, but not in EBNF or XML-Schema and not for XSLT.

For a description of what I want to do: My Editor shows the user the possible syntax-elements of the language XSLT. One can be choosen to write into the file. If the user chooses for example the syntax-element “element”, the following line (exactly as shown) is written into the file:

<xsl:element-name attribute-name=”text”></xsl:element-name>

After that the user can overwrite the “element-name”, “attribute-name” and “text” with concrete names and text. The same should be for every syntax-element of the language.

Can you help me again with this added information?

Thank you very much and sorry for the bad description of my problem.
