xml to r data extraction

[johnmm]

I need to extract data from xml file and plot graphs of:depth vs timestamp. Heading should be the IFC code. I tried using xmlToList and xmlTodataframe, but I failed doing so. I need help. My xml file looks like\[code\] <document> <site> <IFC_code>HONEYCR01</IFC_code> <Latitude>41.960161</Latitude> <Longitude>-90.470759</Longitude> <River>Honey Creek</River> <Road>Hwy 136, 1st Street</Road> <Town>Charlotte</Town> <from_sensor_to_river_bottom>9.35</from_sensor_to_river_bottom> <Unit>foot</Unit> </site> <data> <value> <timestamp>2012-05-17 15:30:03-05</timestamp> <depth>8.53</depth> </value> <value> <timestamp>2012-05-17 14:30:06-05</timestamp> <depth>8.50</depth> </value> <value> <timestamp>2012-05-17 14:15:02-05</timestamp> <depth>8.51</depth> </value> <value> <timestamp>2012-05-17 14:00:12-05</timestamp> <depth>8.50</depth> </value> <value> <timestamp>2012-05-17 13:45:08-05</timestamp> <depth>8.51</depth> </value> </data> </document>\[/code\]
