Once again...Thanks Martin,
So your suggesting I do this...
<html>
<title></title>
<head></head>
<body>
<script language="JavaScript">
var doc = new ActiveXObject('Msxml2.DOMDocument.3.0');
doc.async = false;
if (doc.load('http://xoap.weather.com/weather/local/23218?cc=&dayf=7'))
{
doc.setProperty('SelectionLanguage', 'XPath');
var locEl = doc.selectSingleNode('/wheather/loc');
var dnamEl = loc.selectSingleNode('dnam');
var dnam = dnamEl.text;
var tmEl = loc.selectSingleNode('tm');
var tm = tmEl.text;
}
else
{
//deal with doc.parseError here
}
</script>
<table>
<tr>
<td><span id="dnam"></span></td> <!-- location of weather
bservation -->
<td><span id="tm"></span></td> <!-- time of obsrvation -->
</tr>
</table>
<!-- misc html content here -->
<script language="JavaScript">
var dayElements = doc.selectNodes('/weather/dayf/day');
for (var i = 0, l = dayElements.length; i < l; i++)
{
var dayElement = dayElements[i];
var dayName = dayElement.getAttribute('t'); // e.g. 'Monday'
var hiEl = dayElement.selectSingleNode('hi');
var hi = hiEl.text;
}
</script>
<!-- Display Day 0 -->
<table>
<tr>
<td><span id="t"></span></td> <!-- condition e.g. mostly sunny -->
<td><span id="hi"></span></td> <!-- day 0 forecast high -->
</tr>
</table>
<script language="JavaScript">
var dayElements = doc.selectNodes('/weather/dayf/day');
for (var i = 0, l = dayElements.length; i < l; i++)
{
var dayElement = dayElements[i];
var dayName = dayElement.getAttribute('t'); // e.g. 'Monday'
var hiEl = dayElement.selectSingleNode('hi');
var hi = hiEl.text;
}
</script>
<!-- Display Day 1 -->
<table>
<tr>
<td><span id="t"></span></td> <!-- condition e.g. mostly sunny -->
<td><span id="hi"></span></td> <!-- day 1 forecast high -->
</tr>
</table>
<!-- misc html content here -->
</body>
</html>
<!-- save files as HTA -->
Coffeecup reports an error on line #15... var dnamEl =
loc.selectSingleNode('dnam');
as "loc" being undefined... then nothing happens.
As you can see, I'm probably completely lost, but I wonder if DOM scripting
would make things more simple for me.
And with HTA, I loose the browser toolbar and tabed browsing that I would
have with a HTML file.
Thanks Martin,
Richard in VA.
