["openhab.doc" <openhab.doc@web.de>]

Hi, need help checking a docbook5 xml file.

 

When I run

 

´´´

xsltproc --xinclude --output Test.html /home/mepi/Downloads/docbook-xsl-1.79.2/xhtml/docbook.xsl MyBook.xml
´´´

 

I get following Error:

 

´´´

MyBook.xml:60: namespace error : Namespace prefix xl for href on link is not defined
       If not, see <link xl:href="" <emphasis>the  
                                                               ^
MyBook.xml:69: namespace error : Namespace prefix xl for href on link is not defined
       <link xl:href="" <emphasis>th
´´´

         

What do I wrong?

                                                        ^
When I try to check my File MyBook.xml with xmllint,

 

´´´

xmllint --relaxng /usr/share/xml/docbook5/schema/rng/5.1/docbook.rng MyBook.xml
´´´

 

I get following messages:

 

´´´

MyBook.xml:18: element info: Relax-NG validity error : Element book has extra content: info
MyBook.xml:13: element book: Relax-NG validity error : Expecting element abstract, got book

MyBook.xml:13: element book: Relax-NG validity error : Expecting element example, got book

What does the messages above mean?

´´´

1 <?xml version="1.0" encoding="utf-8"?>
