[PATCH 5/5] parse-xml.c: fixed a small memory leak related to xmlGetProp()

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

test_xslt_transforms():
xmlGetProp uses strdup(), so we have to clear the memory if a pointer
is returned.

xmlFree() doesn't seem very portable (strangly enought), so we
use free(..) directly.
