Description:
------------
We had a problem with typo3 and templavoila after updateing to 5.2.10.
The problem was that the prevues given string with < and > was 
removed in the current version.

We had the extensions 

extension=eaccelerator.so
extension=zip.so
extension=simplexml.so
extension=session.so
extension=xml.so
extension=pcre.so
extension=filter.so
extension=gd.so
extension=json.so
extension=zlib.so
extension=bz2.so
extension=openssl.so
extension=ctype.so
extension=spl.so
extension=dom.so
extension=mysql.so
extension=mcrypt.so

installed

After XML-Write and XML-Reader the behavior becomes the same as with 
the version 5.2.9.

extension=xmlwriter.so
extension=xmlreader.so



Reproduce code:
---------------
<?php

        $data = '<?' . 'xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
   <field_content type="array">
   <vDEF>Casestudy www.blah blah&lt;br&gt;
        &lt;br&gt;
        blah, Agentur f?r Werbung und Kommunikation GmbH&lt;br&gt;
        &lt;a href=&quot;http://www.blah blah/&quot; target=&quot;_blank&quot; style=&quot;color: #000000;&quot;&gt;www.blah blah&lt;/a&gt;</vDEF>
        </field_content>
        </T3FlexForms>';

        $parser = xml_parser_create();
        $vals = $index = $match = Array();

    xml_parser_set_option( $parser, XML_OPTION_CASE_FOLDING, 0 );
    xml_parser_set_option( $parser, XML_OPTION_SKIP_WHITE, 0 );
    xml_parser_set_option( $parser, XML_OPTION_TARGET_ENCODING, 'iso-8859-1' );

    xml_parse_into_struct( $parser, $data, $vals, $index );
         print_r( $vals );

         xml_parser_free( $parser );
?>






Expected result:
----------------
Array
(
    [0] => Array
        (
            [tag] => field_content
            [type] => open
            [level] => 1
            [attributes] => Array
                (
                    [type] => array
                )

            [value] => 
   
        )

    [1] => Array
        (
            [tag] => vDEF
            [type] => complete
            [level] => 2
            [value] => Casestudy www.mohrenbrauerei.at<br>
        <br>
        blah, Agentur f<C3><BC>r Werbung und Kommunikation GmbH<br>
        <a href="http://www.blah blah/" target="_blank" style="color: 
#000000;">www.blah blah</a>
        )

    [2] => Array
        (
            [tag] => field_content
            [value] => 
        
            [type] => cdata
            [level] => 1
        )

    [3] => Array
        (
            [tag] => field_content
            [type] => close
            [level] => 1
        )

)


Actual result:
--------------
Array
(
    [0] => Array
        (
            [tag] => field_content
            [type] => open

                (
                    [type] => array
                )

            [value] => 
   
        )

    [1] => Array

After what comes what now? What do you do get the expected behaviour and what you don't do? Did you really update everything, including those extensions? Hint: Try removing all existing stuff prior to doing 'make install'.

Sorry if my explanation is a bit confusing.

We installed the new version with portupgrade and afterwards
we forced the new installation again with the same result.

We solved the problem but the behavior seems
not to be the same in 5.2.9 and 5.2.10.

When using the xml_parser in 5.2.9 we got the right
result. &lt; and &gt; were in the source and were correct
transformed to < and >.

In 5.2.10 this strings were removed. After additionally 
installing the extensions xml-writer and xml-reader we got 
the same result as in 5.2.9. &gt; and &lt; wasn't removed
anymore. It seems that the encoding and decoding differs
when different extensions are installed.

in 5.2.9 we've installed only xml and all worked perfect.
In 5.2.10 we had to install xml-reader and xml-writer to get
the same result.

Please drop me a note if there is some question open.)
