Hi Marko,

sorry for the delayed answer.

Haven't looked at it yet. Maybe I can manage to do so later on.

Generally speaking: make sure that you parse the innermost block first.
Otherwise you're corrupting the variable cache.
This must to parse the innermost block first is the price of the simpler
block API.

Will have a look at it later on.

Empty block get deleted automatically (unless you touched them to be
preserved).

/**

var $removeVariablesRegExp = "";
        
/**

var $removeUnknownVariables = true;

var $removeEmptyBlocks = true;

No, but PHPDoc uses IT and the new form_flow_layout.inc does also. Maybe
I can give you
an example later this week.

* To add content to block1 you simply type:
* <code>$tpl->setCurrentBlock("block1");</code>
* and repeat this as often as needed:
* <code>
* $tpl->setVariable(...);
* $tpl->parseCurrentBlock();
* </code>
*
* To add content to block2 you would type something like:
* <code>
* $tpl->setCurrentBlock("inner1");
* $tpl->setVariable(...);
* $tpl->parseCurrentBlock();
*
* $tpl->setVariable(...);
* $tpl->parseCurrentBlock();
*
* $tpl->parse("block1");
* </code>
*
* This will result in one repition of block1 which contains two
repitions
* of inner1. inner2 will be removed if $removeEmptyBlock is set to true
which is the default.
*
* Usage:
* <code>
* $tpl = new IntegratedTemplate( [string filerootdir] );
*
* // load a template or set it with setTemplate()
* $tpl->loadTemplatefile( string filename [, boolean
removeUnknownVariables, boolean removeEmptyBlocks] )
*
* // set "global" Variables meaning variables not beeing within a
(inner) block
* $tpl->setVariable( string variablename, mixed value );
*
* // like with the Isotemplates there's a second way to use
setVariable()
* $tpl->setVariable( array ( string varname => mixed value ) );
*
* // Let's use any block, even a deeply nested one
* $tpl->setCurrentBlock( string blockname );
*
* // repeat this as often as you need it.
* $tpl->setVariable( array ( string varname => mixed value ) );
* $tpl->parseCurrentBlock();
*
* // get the parsed template or print it: $tpl->show()
* $tpl->get();

__global__ is an internal placeholder used while processing the
template. Do not play with it unless you know how IT[X] works.
