Description sf 2009-07-03 07:46:54 UTC 
Please describe the problem:
Section 3.3.3 Attribute-Value Normalization (http://www.w3.org/TR/2008/REC-xml-20081126/#AVNormalize) gives three examples. With xmllint the second example cannot be reproduced.


Steps to reproduce:
Execute "xmllint --format --noent test.xml" with test.xml as follows:

<?xml version="1.0"?>
<!DOCTYPE x [
<!ENTITY d "&#xD;">
<!ENTITY a "&#xA;">
<!ENTITY da "&#xD;&#xA;">
]>
<x x="&d;&d;A&a;&#x20;&a;B&da;"/>



Actual results:
<?xml version="1.0"?>
<!DOCTYPE x [
<!ENTITY d "&#xD;">
<!ENTITY a "&#xA;">
<!ENTITY da "&#xD;&#xA;">
]>
<x x="&#13;&#13;A&#10; &#10;B&#13;&#10;"/>


Expected results:
<?xml version="1.0"?>
<!DOCTYPE x [
<!ENTITY d "&#xD;">
<!ENTITY a "&#xA;">
<!ENTITY da "&#xD;&#xA;">
]>
<x x="  A  B  "/>


Does this happen every time?
Yes.

Sorry, no. You misread the spec what you expect should only be
the output for an attribute of type NMTOKENS, which is not the
case in your document !
  Try again and read the 3rd column of the example :-)

Comment 2 sf 2009-07-04 11:19:03 UTC 
I disagree. The third column (CDATA case) in the second example in the spec says #x20 #x20 A #x20 #x20 #x20 B #x20 #x20, which translates to "  A  B  " (mind the number of spaces), not "&#13;&#13;A&#10; &#10;B&#13;&#10;".
Comment 3 Daniel Veillard 2009-08-25 15:22:30 UTC 
Okay, agreed, it's a special recursive treatment for the entities replacement
text. Fixed in git, 

  thanks !

Works for me (2.7.3 patched with http://git.gnome.org/cgit/libxml2/patch/?id=283d50279d2defbcedc940a4261758afa0fe752b).

Thanks
