Please describe the problem:
I'm working with some very long xml files, some have a length of over 400,000 lines.  When I run xmllint it reports all the errors as occuring on line 65,535 (The maximum value of an unsigned 16 bit integer).

Steps to reproduce:
Generate an xml file along these lines

<?xml version="1.0" encoding="UTF-8"?>
<yadayada>
    <foo><bar/></foo>
    <foo><bar/></foo>
    <foo><bar/></foo>
    <foo><bar/></foo>
    <!-- and so on  -->
    
    <!-- then somewhere after 65,535 lines -->
    <foo>
        <this-causes-an-error/>
    </foo>
</yadayada>

This script may be used to generate this sort of file

#!/usr/bin/python

outFile=open('testLineNumbers.xml','w')

outFile.write("""<?xml version="1.0" encoding="UTF-8"?>
<yadayada>
""")

line="<foo><bar/></foo>\n"

# write a bunch of OK lines
for i in range(65540):
    outFile.write(line)
    
# write a bad line
outFile.write('<foo><this-causes-an-error/></foo>\n')

# write 10 more good lines
for i in range(10):
    outFile.write(line)


outFile.write('</yadayada>')
outFile.close()


Validate the file against this schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="yadayada">
    <xs:complexType>
        <xs:sequence>
            <xs:element ref="foo" maxOccurs="unbounded"/>
        </xs:sequence>
    </xs:complexType>
  </xs:element>
  
  <xs:element name="foo">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="bar"/>
        </xs:sequence>
    </xs:complexType>
  </xs:element>

</xs:schema>




Actual results:
You get the following error:

testLineNumbers.xml:65535: element foo: Schemas validity error : Element 'foo' [CT local]: The element content is not valid.
testLineNumbers.xml fails to validate

Looking at the line 65535 (vi +65535 testLineNumbers.xml) indicates that the line number is not the correct location of the error


Expected results:
Line number should be correct.  I'm guessing that the type of the variable that tracks the line number must be changed short to int or int to long.  The format specifier in the printf that displays this variable may also need to be changed.

Does this happen every time?
yes
