Capture text created by HTML

I want to capture the text created by a web page.

Here is the page I am looking at http://www.metoffice.gov.gg/livedata.html

The data I want is things like the temperature, wind speed etc. The HTML does not seem to contain any of the displayed data.

I have looked at WebView which displays the page perfectly, I just can't see how to get at the displayed data.

Yep , what he said.

it's here..

Code: Select all

<iframe id="temp"
src="http://www.metoffice.gov.gg/met/PA50.html" height ="100%" width ="100%" frameborder="0" scrolling="no" allowtransparency="true" background="none">
</iframe>


</div>
<div class="Live1">
    <iframe id="wind"
src="http://www.metoffice.gov.gg/met/wind2.html" height ="100%" width="100%" frameborder="0" scrolling="no">
</iframe>

so you want to load
http://www.metoffice.gov.gg/met/PA50.html
and
http://www.metoffice.gov.gg/met/wind2.html

then extract the data from the tables

wind2.html looks like this..

Code: Select all

<html><META HTTP-EQUIV=REFRESH CONTENT=30; URL=http://wind2.html><link href="stylewind.css" type="text/css" rel="stylesheet"><body leftmargin=15><div align=center><center><table><tr><td width=224 height=150 align=center><div align=left><table border=0><tr><td width=219 height=50><font size=4>&nbsp;Mean Direction (°T)</font></td></tr><tr><td width=219 height=50><font size=4>&nbsp;Mean Wind Speed (knots)</font></td></tr><tr><td width=219 height=50><font size=4>&nbsp;10 min.

Well done Bruce, you're a star! I'll have a go at that.

I has a little play and did this for wind2.html

it's only issue it the "degrees" sign in "Mean Direction (°T)" i could not convert that.

it makes a String[][] array
[title, data1, data2]
[title, data1, data2]

Thanks for the program. I cheated a bit on the HTML clean up by shelling to html2text. Here is my effort so far. VERY early days....
