There's no simple way to make the doc/examples tests handle different configurations. But these tests aren't especially valuable, so remove the result file checks.

* section: xmlReader
|
|
* synopsis: Parse multiple XML files reusing an xmlReader
|
|
* purpose: Demonstrate the use of xmlReaderForFile() and
|
|
* xmlReaderNewFile to parse XML files while reusing the reader object
|
|
* and parser context. (Note that the XMLReader functions require
|
|
* libxml2 version later than 2.6.)
|
|
* usage: reader4 <filename> [ filename ... ]
|
|
* test: reader4 test1.xml test2.xml test3.xml > reader4.tmp && diff reader4.tmp $(srcdir)/reader4.res
