XSLT in PHP

Hi List, XSLT seems to be such an hot topic these days now i tried it out and i find it cool too. But is there anyway how i can make XSLT less strict? When i make a stylesheet XSLT is too picky..I can't make an XSLT stylesheet very fast because you have to close everything correct etc.. When i design a template i cannot do.. <blah> tralala <br> <= ERROR has to be <br/> </blah> And so are there a numerous things that have to be done.. Is there someway how i can turn that strictness thingie of? Warm regards, EMile Bosch
