Sorry for the late reply.

Absolutely, and I have. All the entities are part of the common ISO sets
but the customer can't handle them.

I've decided on editing my iso-???.ent files to accomplish this on my end
before delivery.


thanks,

--noent the parser is instructed to not generate any entity reference node.
So at that point the parser has no information left allowing to represent
the entity when reserializing the tree:

paphio:~/XML -> cat tst.xml
<!DOCTYPE doc SYSTEM "foo.dtd">
<doc>hello this is &foo; some text</doc>
paphio:~/XML -> cat foo.dtd
<!ELEMENT doc (CDATA)>
paphio:~/XML -> ./xmllint --shell --valid --debug --noent tst.xml
tst.xml:2: error: Entity 'foo' not defined
<doc>hello this is &foo; some text</doc>
                        ^
tst.xml:2: validity error: Element doc content doesn't follow the DTD
Expecting (CDATA), got (CDATA)
<doc>hello this is &foo; some text</doc>
                                       ^
/ > ls
?--        1 doc
---        1 doc
/ > cd doc
doc > ls
t--       24 hello this is  some text
doc >

  Actually when there is an undeclared entity libxml doesn't produce
any entity reference in the generated tree, whether --noent is declared or
not:

(gdb) p *doc->children->next->children
$4 = {_private = 0x0, type = XML_TEXT_NODE, name = 0x80a3260 "text",
  children = 0x0, last = 0x0, parent = 0x80f4ce0, next = 0x0, prev = 0x0,
  doc = 0x80e4960, ns = 0x0, content = 0x80e4e60 "hello this is  some text",
  properties = 0x0, nsDef = 0x0}

  This is an error handling condition, I don't know what's the most
appropriate
thing to do in this case.
