Php regular expression to match the dede template tag code

Use regular expressions to match dede tags. For more information about template tags like dedecms, see dedecms template tags. Html code

The code is as follows:

{T: arc row = '10 '}
{T: field. title /}
{T: list row = '5 '}
{T: field. title /}
{T: list row = '5 '}
{T: field. title /}
{/T: list} {t: field. title /}
{/T: list} {t: field. title /}
{/T: arc}
{T: channelartlist
Row = '6'
}

{T: field name = 'typename'/} {t: field. typename /}

{T: arclist titlelen = '42' row = '10 '}

• [Field: title/]


• ([Field: sendtime function = "MyDate ('M-D', @ me)"/])

{/T: arclist}

{/T: channelartlist
}
{T: global. pai_title
//} {T: var. cmd_title/} {t: global. cmd_webname/} {t: global. cmd_title/} {t: var. cmd_title /}
{T: field. title function = "Html2Text (@ me )"/}
{T: include
Filename = "header.htm "/}
{T: include filename = "header.htm"

{T: field. title function = 'html2text (@ me) '} {/t: field
}

[Field: id/] [field: typename/]

}
{T: channel typeid = '1'} [field: id/] [field: typename/] {/t: channel}
{T: channel typeid = '1'} [field: id/]
