DTD (or any other schema-like information) can be used to generate code to handle the conforming instances directly. Instead of looking into the schema for each element, the code already knows what element to expect, so it's definitely faster.

For an example, see Treex::PML where we used the same technique for a PML-schema.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
