I have an xml file which contains schedules for all employees. How do I extract data from this file for a specific employee? Below is a snippet of the code, but this loads all employees.
DataSet allSchedulesDs = new DataSet();
// get schedules
allSchedulesDs.ReadXml(myFilepath + "AllSchedules.xml");
scheduleCount = allSchedulesDs.Tables["ALLSCHEDULES"].Rows.Count - 1;
for (int j = 0; j <= scheduleCount; j++)
{
// check all xml file for badge number input
if ((string)allSchedulesDs.Tables["ALLSCHEDULES"].Rows[j][0] == textBoxBadgeId.Text.PadLeft(5, '0'))
// record found set up for display
{
// this gets all schedules need to limit display to just this badge number
scheduleList.DataSource = allSchedulesDs.Tables["ALLSCHEDULES"].DefaultView;
scheduleList.DataBind();
}
}

Hi everyone,
I first would like to warn you that I'm a newbie programmer. So if I have left out important code for you guys to determine what I'm doing wrong, let me know. 
I am making a PocketPC application using C# and an XML file as a database. I would like to display the corresponding JPG image in a PictureBox, or somewhere on the main page.
A sample of my xml file. The bolded line is the picture reference.
<fragenkatalog><br />
<ca_id>4</ca_id><br />
<ca_titel>head ap</ca_titel><br />
<ca_bildurl1>kopf_ap.jpg</ca_bildurl1><br />
<ca_disabled>0</ca_disabled><br />
<ca_alter>999</ca_alter><br />
<ca_sex>n</ca_sex><br />
</fragenkatalog>
This is what I have, which doesn't work.
<br />
ca_bildurl.DataBindings.Add("Image",dt,"ca_bildurl1");
The ID is chosen from a ListBox, and the corresponding data is displayed on the screen.
Any help would be appreciated! Thanks!
M.

Please repost your XML with < and > instead of the < and > symbols.

Trouble using sql:relation/sql:relationship in xsd file ...
Hi ...
I am attempting to use the sql:relation annotation and am having some troubles. I have used it successfull with the MS Sample (Customer / Order) where all the data is contained in elements (example below).
<code><ROOT>
<Customers>
<CustomerID>1111</CustomerID>
<SynchID>700</SynchID>
<CompanyName>Sean Chai</CompanyName>
<City>NY</City>
<Order OrderID="1" />
<Order OrderID="2" />
</Customers>
</ROOT>
In the xml that I am having trouble with the data is contained in attributes. In the code below I get the following
error when executing the bulk insert.
Any comments ?
Thanks !!
Chris

I am not too hot on XML etc, and would appreciate a little help.
I have a large XML document and would like to know if it is possible to find a node within the document that has a specific value, (not attribute), with the .SelectNode( ... ) function? All that I have read so far leads me to believe that I will have to loop through the document searching for a node with a specific value rather than being able to home in on it with a clever XPath expression!
|

If you have
<doc>
<node>1</node>
<node>2</node>
</doc>
then the XPath expression node[text()='1'] should select the node with text contents of '1' (i.e. the first node in that document)

That's not completely true. You'll have to already be in the doc element, for that to work. If you're not already traversing thru the XML, you'll need to specify the absolute path to a property you want. You can do this by typing /doc/node. That will give you the value within the node element. If you have attributes, they need to be preceded with the at (@) symbol.

Hi
I have lot of config data in a table which I want to put in .config file.
Is there any tool using which I can save the data into customized xml file?
Please advice. Thanks
Pankaj

May be you should place your data in a table and use the forXML T-SQl extension.
This can be done on MS SQL and SQL Anywhere.
The other option is to put it ina Access tbale and export in XML format.

I'm fairly new to XML and I'm just wondering if there is any difference between using elements or attributes to store data in an XML file. From a programatic view is is better to use one or the other for having to read in the file and such? Are there any performance differences? Is one more flexible than the other?
Any information on the topic is very appreciated.

There are no rules about when to use attributes, and when to use child elements. My experience is that attributes are handy in HTML, but in XML you should try to avoid them. Use child elements if the information feels like data.
Some of the problems with using attributes are:
.attributes cannot contain multiple values (child elements can)
.attributes are not easily expandable (for future changes)
.attributes cannot describe structures (child elements can)
.attributes are more difficult to manipulate by program code
.attribute values are not easy to test against a Document Type
.If you use attributes as containers for data, you end up with documents that are difficult to read and maintain.
Try to use elements to describe data. Use attributes only to provide information that is not relevant to the data.

I have a project, in which we need to read in an XML file. But, when we read in that file, we need to parse it so that only designated data is used. So we parsed it into a string. We now are running into the difficulty of passing the String into the XSLT.
Is there a way to convert a String with XSLT, or do we need to rewrite the XML file?
TIA,
Scott

You can load the tring into an XMLDocument object much like you load it from file.
HRESULT loadXML(BSTR bstrXML,VARIANT_BOOL * isSuccessful);
This migth be an Microsoft extension of the DOM model, but it exists in
MSXML.
Then it is possible to transform it using the transformNode method of the XMLDocument object.
HRESULT transformNode(IXMLDOMNode *stylesheet, BSTR *xmlString);

Hi
i have an webpage which at the time of loading populates a table. the user can also populate the table by clicking on a button. There is a column called seqno which is populated in "space-SeqNo-space" fashion at the time of loading time population. Same thing when trying to accomplish through javascript it is seen that xsl loading time space is not identical with javascript space.
for example:
XSL:
" 1 "
" 2 " etc.
Javascript:
" 1 "
" 2 "
(here in example to show the effect i am using two space for javascript)
seeming an indentation problem.
My resolution is 1152 X 864.
Another thing for same color-code from javascript and from xsl it shows different color.
Thanks in advance

Make sure you escape your '&' characters. I can't see your XSL output, but I'm guessing the problem is that you're using  , which is the equivalent of (a non-breaking space) in HTML. Try modifying the JavaScript to either parse   and as well as spaces or simply replace all occurrences of   and with a space.
xslOutput = xslOutput.replace(' ', ' ');
xslOutput = xslOutput.replace(' ', ' ');That should work... assuming I've guessed the problem correctly.

It should not be much of a problem. I do it like this in a project (With all error handling removed. It just clutters up the example.)
int CHookApp::LoadXML (int rsrc, MSXML2::IXMLDOMDocument2Ptr& xml, CString& errMsg)
{
HRSRC hXSLResourceInfoBlock;
HGLOBAL hXSLResource;<br>
hXSLResourceInfoBlock = ::FindResource (m_hInstance, MAKEINTRESOURCE(rsrc), "XSL");<br>
if (hXSLResourceInfoBlock)
hXSLResource = LoadResource (m_hInstance, hXSLResourceInfoBlock);<br>
if (hXSLResourceInfoBlock == NULL || hXSLResource == NULL)
return -1;<br>
try {
_bstr_t xmlText ((char*)LockResource (hXSLResource));
if (xml->loadXML ( xmlText ) == VARIANT_FALSE)
return -1;<br>
}
catch (...) {
return -1;<br>
}<br>
return 0;
}
I wonder why my empty lines are removed from the <pre> block above. It remained in another reply of mine.......

Dear Experts,
I need some information on dynamic updation of XML file.
Our application asks the user to insert a file by giving the user browsing option.
We want our XML file (which contains the information about the residing files) to be dynamically updated as soon user specifies the path of the inserted file.
The next task is to dynamically update the XML file once the user select the file to be deleted by clicking on the Application UI.
We have to develop the code in C++.
Kindly send across your suggestion, opinion and helpful codes.

Mayank Srivastava
