Php regular expression to match the dede template tag code _ PHP Tutorial

Php regular expression to match the dede template tag code. The code for copying html code is as follows :! DOCTYPEhtmlPUBLIC-W3CDTDXHTML1.0TransitionalENwww.w3.orgTRxhtml1DTDxhtml1-transitional.dtdhtmlxmlnswww. html code

The code is as follows:

{T: arc row = '10 '}

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

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