Hi,

I'm trying to display the data from my typed dataset on a page using
the Xml web control.

I have the following code:


Xm1.Document = new XmlDataDocument(ds);


Using the debugger, I found that the xml representation of my dataset
looks like the following:

[code:1:b261030e14]
<dsData>
<Entry>
<Title>Test</Title>
<Description>This is a test</Description>
</Entry>
</dsData>
[/code:1:b261030e14]

My xsl file looks like this

[code:1:b261030e14]
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:for-each select="dsData/Entry">
<div class="Entry">
<div class="EntryTitle">
<xsl:value-of select="Title"/>
</div>
<div class="EntryDescription">
<xsl:value-of select="Description"/>
</div>
</div>
</xsl:for-each>
</xsl:template>
</xsl"stylesheet>
[/code:1:b261030e14]

Using this stylesheet, nothing is displayed/transformed. I know that
it must be a stylesheet problem because if I don't set the
TransformSource property of the Xml control the raw xml of the
dataset (XmlDataDocument) is displayed.

I hope that someone understands this, as I'm lost.

Thanks,
Cyp.

If you use XSL file to transfer XML data to other file,
e.g. html, you should use class XslTransform as a bridge
to conduct output:

XmlDataDocument xmlDoc = new XmlDataDocument(ds);
XslTransform xslTran = new XslTransform();
xslTran.Load(xslFile);
using(StreamWriter writer = new StreamWriter
(htmFile,false))
{
xslTran.Transform(xmlDoc, null, writer,null);
}

Hope it gives you some help.

Hi,

Thanks for your reply - I really appreciate it. However, I'm not sure
it's what I'm after, as I have a page with existing content on it.
I'm using the xml control to display specific data that changes. I'm
not sure how to use your code in my situation.

Regards,
Cyp.

Strange, but I got it work. I deleted the dataset, and created a new
one. However, this time I didn't create a typed dataset - and it
worked. I wonder how come it didn't work with a typed dataset?

Anyhow,
This leds to another XPath question, since the structure of my xml
changes.

I have the following xml:

<dsData>
<Entry>
<EntryID>10</EntryID>
<Title>Testing an entry</Title>
</Entry>
<Comment>
<CommentID>1</CommentID>
<EntryID>10</EntryID>
</Comment>
</dsData>


When I'm in a for-each loop that's selecting all Entry elements, I
want to display the total number of Comment elements that have the
current Entry's EntryID.

I have the following, but doesn't work:

[code:1:6efef00bb8]
<xsl:for-each select="dsData/Entry">
<!-- other content goes here -->
<value-of select="count(/Comment[EntryID =
{EntryID}])"/>
</xsl:for-each>
[/code:1:6efef00bb8]

Thanks!!!!
Cyp.

you might use
<xsl:number expr="count()" />
instead of
<value-of select="count()"/>
