This turned out not so straightforward but hopefully this could be helpful to others. The biggest complication was returning non-string from callback function of preg_replace. Thanks all who tried to help! <pre><code>class Parser { public $ret=array(); function loadTemplateFromString($str){ $this->parsed_template=$this->tags=array(); if(!$str){ return; } var_dump($str); /* First expand self-closing tags <?$tag?> -> <?tag?><?/tag?> */ $str=preg_replace('/<\?\$([\w]+)\?>/','<?\1?><?/\1?>',$str); /* Next fix short ending tag <?tag?> <?/?> -> <?tag?> <?/?> */ $x=preg_replace_callback('/.*?<\?\/\?>/',function($x){ return preg_replace('/(.*<\?([^\/][\w]+)\?>)(.*?)(<\?\/?\?>)/', '\1\3<?/\2?>',$x[0]); },$str); /* Finally recursively build tag structure */ $this->recursiveReplace($x); } function recursiveReplace($x){ if(is_array($x)){ // Called recursively $tmp2=$this->ret;$this->ret=array(); }else{ $x=array(4=>$x); $tmp2=null; } $y=preg_replace_callback('/(.*?)(<\?([^\/$][\w]+)\?>)(.*?)(<\?\/(\3)?\?>)(.*?)/', array($this,'recursiveReplace'),$x[4]); $this->ret[]=$y; if($tmp2===null)return; $tmp=$this->ret; $this->ret=$tmp2; $this->ret[]=$x[1]; $this->ret[]=$tmp; return ''; } } $p=new Parser(); $p->loadTemplateFromString('bla <?name?> name <?/name?> bla bla <?$surname?> bla '. '<?middle?> mm <?/?> blah <?outer?> you <?inner?> are <?/?> inside <?/outer?>'. ' bobobo'); var_dump($p->ret); </code></pre> This outputs: <pre><code>array 0 => string 'bla ' (length=4) 1 => array 0 => string ' name ' (length=6) 2 => string ' bla bla ' (length=9) 3 => array 0 => string '' (length=0) 4 => string ' bla ' (length=5) 5 => array 0 => string ' mm ' (length=4) 6 => string ' blah ' (length=6) 7 => array 0 => string ' you ' (length=5) 1 => array 0 => string ' are ' (length=5) 2 => string ' inside ' (length=8) 8 => string ' bobobo' (length=7) </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
