Is there a way to read the doctype declaration of an xml using xslt?
Example XML doctype declaration:
<!DOCTYPE article PUBLIC "-//NLM//DTD JATS (Z39.96) Journal Archiving and Interchange DTD with OASIS Tables with MathML3 v1.1 20151215//EN" "JATS-archive-oasis-article1-mathml3.dtd">
I need to check if the doctype declaration contains the specific dtd mention above if the condition is true then I need to generate an element in my xml output.
I tried unparsed-text-lines() and unparsed-text(). Locally it working by supplying the uri of the xml file but in pipeline its not.
Is there a way to read those?
I found saxon:schema function but not sure how use it or if its for xml and xsd combination only not for xml and dtd thing.

The DOCTYPE declaration is not part of the XDM data model, which means it's not part of the document that can be accessed using standard XSLT/XPath constructs.
As Martin points out, it is made available to SAX applications (specifically, by notifying startDTD and endDTD to the LexicalHandler). You could exploit this by writing a SAX filter that converts the DOCTYPE declaration to a suitable processing instruction. Your URIResolver could return a SAXSource that incorporates this filter; the DOCTYPE declaration would then be accessible to the XSLT code as a processing instruction child of the document (root) node.
