[VuFind-Tech] libxml2 bug workaround

[Tuan N. <tu...@yo...>]

I recently ran in to several records can not be displayed, it turned  
out that it has to do with the following related bugs in the XML  
parser which XML/Unserializer.php rely on.

http://pear.php.net/bugs/bug.php?id=16153
http://bugs.php.net/bug.php?id=45996

If you have & or < or > etc... in your marc records, you may have run  
into this bug, took us a while to track this down. Instead of  
downgrade/upgrade your libxml2/php/apache stack, you can simply add

   <xsl:output method="xml" indent="yes" cdata-section- 
elements="fullrecord"/>

to web/xsl/solr-convert.xsl
