...ant-section-of-doc.pdf

Stuck ...can't get sapply and xmlTreeParse working
Can't seem to get the code below working. It gets stuck on line 24 inside the
function hm; comments show the line in question. The function hm is called
by sapply and is at the bottom of the code. Other stuff above line 24 works

be using a different apply function or am I doing something wrong with
xmlTreeParse ?
