If I go directly to the XML link:
<http://subtitles.secure.content.itv.com/CATCHUP/a852d6cd/1a2b/4152/9f94/e88bbb226a2d/2-3290-0021-001_JudgeRinder_TX050115.xml?__gda__=1422344440_9e4dd8f44a6f2503379f85c8b4df3f86&fileExt=.xml>

I am able to download the file. However, I want to download all the .XML files
under the directory structure <http://subtitles.secure.content.itv.com>

I am getting this error if I try to do this with robots.txt turned off or on:
