Comprehension question about docbook5 and xmllint

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

Hi,

 

I try to create one big xml file from my modularized documents with xmllint.

 

My files can be found here:

https://github.com/mepi0011/darktable/tree/docBook5_port/doc/usermanual

 

The Command I use is:

 

xmllint --xinclude --output big.xml darktable.xml

But I run into some errors:

 

darktable.xml:32: parser error : Entity 'eacute' not defined
       Kazik, Eckhart Pedersen, Edouard Gomez, Fr&eacute;d&eacute;ric Grollier,
                                                         ^
darktable.xml:32: parser error : Entity 'eacute' not defined
       Kazik, Eckhart Pedersen, Edouard Gomez, Fr&eacute;d&eacute;ric Grollier,
                                                                  ^

If I comment out the corresponding lines in the document darktable.xml, the command runs without further errors. Although entities are used in the documents inserted with Xinclude. The subdocuments always link to the same docbook.ent file in the same folder as darktable.xml.

If I apply the command individually to subdocuments, I also receive the corresponding error messages.

 

Why do I get the error messages?

Is this caused by my declaration of entities or xmllint?

 

Thanks

Pierre
