There is somethingI don’t understand about the behaviour of the pretty_print function (or is it a method??) I work exclusively with linguistically annotated texts where every token is wrapped in a <w> element. And pretty_print does a nice job with it. I often edit these files, updating, splitting, joining, or deleting particular element. If I create another element and use ‘addnext’ to insert it as a right sibling, pretty_print fails and doesn’t print it in a new line. Something like <w lemma="the" pos="d" xml:id="b2afn-048-a-0570" ana="the/d">The</w> <w xml:id="b2afn-048-a-0580" lemma="〈…〉" pos="zz" ana="〈…〉/zz">〈…〉</w> Becomes <w lemma="there" pos="av" xml:id="b2afn-048-a-0570" ana="the/d">There</w> <w xml:id="b2afn-048-a-0580" lemma="be" pos="vvb" ana="〈…〉/zz" >be</w><w xml:id="b2afn-048-a-0581" lemma="n2" pos="n2" reg="ravens">rauyns</w> As I write this, it occurs to me that this may have nothing with pretty_print but with what addnext does or doesn’t do. But is there a routine that would guarantee that newly inserted element would by default display with the same indentation as its left sibling? MM
