php代码
代码如下:
<?php
$str = file_get_contents("test.htm");
$skstr="{";
$skdstr="t:";
$sdstr="}";
//$reg="/{t:.*?(?://).*?}/si";//此无法匹配嵌套,只能一层 si s: 使前面的. 包括换行符 i:不区分大小写
//$reg="/({t:*[^{]*//}|{t:*[^}]*}([^{]|(?R))*{//t:.*?})/si";无限嵌套都可截取.
$reg='/('.$skstr.$skdstr.'*[^'.$skstr.']*//'.$sdstr.'|'.$skstr.$skdstr.'*[^'.$sdstr.']*'.$sdstr.'([^'.$skstr.']|(?R))*'.$skstr.'//'.$skdstr.'.*?'.$sdstr.')/si';
preg_match_all($reg,$str,$m);
/*echo "<pre>";print_r($m[0]);echo "</pre>";exit();*/
$CTags=array();
$glarr1=array($skstr.$skdstr=>'');//array('{t:'=>'');前缀
$glarr2=array('"'=>'','/''=>'','$'=>'','/'=>'');
/*
{t:array typeid='1'}[field:typename/]{/t:array}
{t:global.title function="html2text(@me)"/}
*/
foreach($m[0] as $k=>$v){
$rarr=array();
$rarr['str']=$v; //原模板字符串
$vs=explode('}',$v); //分割取得第一部分 {t:array typeid='1'
$va=explode(' ',$vs[0]); //分割属性 " {t:array " , " typeid='1' "
$vb=explode('.',$va[0]); //分割标签名和字段名 {t:global.title
$rarr['tagname']=trim(strtr(strtolower($vb[0]),$glarr1));//过滤前缀{t: 取得标签名 array 或 golbal
$rarr['tagfield']=strtr($vb[1],$glarr2); //取得字段名 title
