Hi ,
Is there any way to export the .aspx file as XML file or vice varsa?
|
|
|
|
|
What are you trying to export? The source code or listing in the aspx? Are you trying to write XML output from an aspx? Do you want the code-behind embedded in XML? Please be more specific.

can anyone sujest me a method or show a sample code in whatever technology wich would help me load c++ objects from XML
like i would have
class A
{
int a;
int b;
A(int c, int d} {a=c; b=d;}
}
and xml <A a='2', b='3'></A>
and in result i would get A a = new A(2,3).
and also i would later on want to save my objects to xml again

If all your class variables are structures and not classes ( I mean int, double, float unlike CString, CList ) you can save the size of each variable in the XML file and then when you read it then just go over all elements and copy them to the class at the write position.
You should also save the type of the variables.
Something like this:
<A>
<a Size="4" Type="Int32">2</a>
<b Size="4" Type="Int32">3</b>
</A>
When you want to copy the objects from the XML you'll have to convert the string to the desired type and then copy the object to the write position in the class.
something like this:
int offset= 0;
int XMLValue;
int XMLVarSize;
A obj = new A();
Foreach Node In Nodes
{
memcpy( (LPBYTE)obj + offset, &XMLValue, XMLVarSize);
offset += XMLVarSize;
}
Good luck

I have a web spider once it finds a page I need to convert that page into XML, it can be any page with many different formats. Is there a component I can use for that?
Does anyone know a really nice and fast way to do it?

Um... HTML is a subset of XML. Just by the mere fact that you're getting HTML from the site, you already have XML. Are you trying to use a certain portion of it? Are you worried about the well-formedness of the HTML? Where are you having the problem?

No HTML is not a subset of XML. XHTML is XML. HTML is not XML.

True, and I stand corrected, but if you've got non-XHTML HTML, good luck loading it into anything other than a browser. Luckily, many modern sites deliver XHTML.
I don't know of anything that converts HTML to XHTML, but I'm sure it's been written. Writing one yourself is an interesting regex exercise that'll be left to the reader.
Short of that, there's always running string processing routines on the HTML and whacking the results into an XML DOM. Seems like it'd be an extra step in many situations, though.

There have been attempts. Last time I checked ( 18 months or so), I was unable to find anything that actually worked on "real" HTML. In other words it worked depending on the HTML so... sometimes.

|

Yep! I found some components but I couldn't fine one that worked all the time... They worked for simple scenarios but complex scenarios they didn't..

Not true, there's a lot of tags that do not respect XML format like "br" "img" "input" and you are not force to close a tag in HTML you can leave it open if you want, that is where I am having my problem...
Thanks for the reply

HtmlTidy [^]will read in badly formed html and can chuck out well-formed xhtml for you. You may be able to use either P/Invoke or if you prefer you can use the command-line version. I havn't investigated.
HtmlTidy is recommended by the W3C for tidying up code and as far as I know it's the only one that people accept works almost all of the time. In fact I'm suprised you havn't come across it. 
You know you're a Land Rover owner when the best route from point A to point B is through the mud.

Hello,
Let say I have the following XML file :
<Patients>
<Patient>
<ID>100</ID>
<NAME>Sarah Readings</NAME>
<DESC>flu</DESC>
<FORMULA>
<PARAM>panadol</PARAM>
<PARAM>linsep</PARAM>
</FORMULA>
</Patient>
</Patients>
I would like to display this data in a DataGridView table. Normally I would load it to a DataSet and map it to a DataGridView. However, as the node <FORMULA> would have multiple children nodes <PARAM> this could not be done.
I imagine the output table would have two rows for this single record. With each row having the same identical <ID>, <NAME>,<DESC> value, but different <PARAM> value.
But I am not really sure. Could anyone suggest how to display this in correct way in DataGridView ? or any article sources that might help ( does this have anything to do with normalization) ?
Many thanks and regards,
Sharvie

You can use CDATA to handle "&". However, you need to post some code to demonstrate exactly what you are trying to do.

Hi
i opened the xml file and then after updating when i want to save it .It gives me Error
See the code
try
{
XmlNode xmlnode;
XmlDocument xdoc=new XmlDocument();
xdoc.Load(@"C:\VirtualDirectory\XmlApplication\myfile.xml");
XmlDocumentFragment docFrag=xdoc.CreateDocumentFragment();
docFrag.InnerXml="<add>this to it";
xmlnode=xdoc.DocumentElement.FirstChild;
xmlnode.InsertAfter(docFrag,xmlnode.LastChild);
xdoc.Save(@"C:\VirtualDirectory\XmlApplication\myfile.xml"); // Here it gives Error
}
catch(Exception ex)
{
ex.ToString();
}

Your code appears to be okay. However, your error may be based on your XML document structure. You need to post the error message!
Also, if you are using ASP.NET, you need to give ASP.NET the permission to write the file to the host server's file system.
