I am looking to extract the data from a webpage. It is a dynamic page
so I am writing a java class to download it but I can?t find the url.
I can explain with a simple example. If you go on www.betfair.com. On
the left you see a full list of the market. I need to download this
list of markets. This is a tree. The data is on 2 files. The first one
is
http://www.betfair.com/Menu.do?timeZone=Europe/London&region=GBR_IRL&locale=en_GB&brand=betfair
You can go in internet explorer, add the address and check the source.
I need the url for the second file. I am going to select a simple
example to explain the second page.
From www.betfair.com, if you select politics then UK, then Next
General Election you can see that there are 2 markets called ?Most
seats? and ?Overall majority?. In this example, there are only 2
markets but it could be a lot more. I have chosen this example because
it should stay the same over the next weeks. I need the url of the
page with the data for the markets. (list of names)

If you look at the source of the first file, you can see the different
nodes for politics.
2378961~0~Politics~0|5589635~2378961~Czech
Republic~1|5519298~2378961~European~1|2451793~2378961~Ireland~1|4577453~2378961~Sweden~1|2707982~2378961~UK~1|5387309~2707982~Blaenau

Election~1|2839625~2378961~USA~0|2839626~2839625~2008
Election~1|72382~0~Pool~0
You can see UK and Next General Election. But you can?t see ?most
seats? and ?overall majority?. I need to see the file with the data
containing the list of markets. The file should show a list of all the
markets available, in that case the name of the 2 markets. I can?t
find the url for the second part.
If you can give me the url containing the list of markets and I can
see the source file by typing the url in internet explorer, that
should be enough and I can add the url in my java class.
I have tried different urls but I did not manage to find out the
correct one. I thought it will be
http://www.betfair.com/menu/LoadMenuNodesAction.do?sReturnPath=parent.frames['menu']&method=getMenuEvents&menuNodeId=2725553&strArrayName=allSkeletonArray&iParentID=2725553&layerName=myMarketsTreeContainer&strMenuPathArrayName=allPathArray&menuPathLayer=menu
for the list of markets in next general election but when I check the
source the data is not there.
The number 2725553 is the ID for next general election.
