Please tell me about following?
What is difference between Declaration Element or Processing Instruction.
Is Declaration Element is necessary for XML file. It should be first element.
Which one is root element in an XML file.
How many times a Processing Instruction can be in an XML file.
What is meant by "Content" in an XML file.
Thanks.

Use the DOM. Take a look around for examples and tutorials. This site (CodeProject) has Articles. There are many others as well for example on msdn.microsoft.com Google is a helpful search tool for finding articles and examples on just about any aspect of software development.

Here is your answer in some example code in C++/CLI with an important message for you in the inserted <body> element.
using namespace System;
using namespace System::Xml;
int main(array<System::String ^> ^args)
{
String ^xml =
L"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
L"<note>"
L"<to>dayakar_dn</to>"
L"<from>George L. Jackson</from>"
L"<heading>Reminder</heading>"
L"</note>";
XmlDocument ^doc = gcnew XmlDocument;
doc->LoadXml(xml);
XmlText ^text = doc->CreateTextNode(
L"Please, search with Google first to find your answers.");
XmlElement ^element = doc->CreateElement(L"body");
element->AppendChild(text);
doc->DocumentElement->AppendChild(element);
Console::WriteLine(doc->OuterXml);
return 0;
}

I'm a current MCAD student. Hope someone can help me with a small query. I am working on an application that saves student records to an xml file. Through using an Xml Schema, a dataset, a new student row and the WriteXml method, I can save a new record to an xml file.
However, if I display an existing record to a series of textboxes and want to amend the record, how do I save the amended record back to the xml file. If I find a student row using the Student ID, populate the textboxes with the details, then use WriteXml method again, that saves a new record to the file instead of amending the existing records. I therefore conclude this is the wrong way of doing things so I am asking for some help.

So you are using the .Net framework DataSet? If so you are not handling the DataSet properly that results in a "new" row rather than updating the existing row.
Also in the future you should post .NET questions "the" appropriate .NET forums here on CodeProject (C#, VB.NET, .NET Framework, ASP.NET, ADO.NET )

Hi,
I want to use javascript for adding and deleting data from an existing XML file. I want to use XML as data file for a small javascript based application. I can load the xml file and show data in the application but I am not sure how to go about in adding and deleting data from it's XML elements.
Is there any link or sample code which can help me.
Thank you,

Hello All,
My situation is this. At the company i work, we have a portal and we want add a kind of file Management system to the portal, so that the users can upload files to our repository. The current way that we have is that all documents related to every single client resides in its own directory. This files need to be categorized according to a series of parameters. So I've come to a conclusion of identifying the documents through labels or adjectives (as in GMAIL), put a label for every parameter that we want to identify the file.
My best conclusion is to use XML inside every directory, have a element tab for every doc and just add element labels under every doc. Neat idea right! 
Great my problem is now I've never worked with XML before, so would like someone that reads this, point me in the right direction in what do i have to study to accomplish this.
Thanks for your time.

I guess with google or the search engine of your choice you should find plenty tutorials on XML (and .NET).
Furthermore you should take a look at the documentation of the System.Xml namespace and the contained classes which presents various examples and links for further reading.

I'd use http://www.w3schools.com/ for learning things like xsd / xpath and as a reference when you forget stuff or know what you want to do but just need a little help doing it.
if you are using .Net, create yourself a xmldocument call doc.loadXML("<rootnode>") and have a play. If you are using vb6 reference msxml(N).dll where (N) is whatever version we are at now and create a DOMDocument40 object
you'll find you need to do CreateElement / CreateAttribute and AppendChild to add new nodes to the basic document.
SelectNodes / SelectSingleNode will find you bits of the tree and that's where the xpath tutorials on w3school will help.

my XML doc does something like this:
< list>
< listitem>
< para>some text< /para>
< block>some text< /block>
< content>some text< /content>
< list>
< listitem>
< para>some text< /para>
< /listitem>
< /list>
< /listitem>
< /list>
that is, lists contain listitems, which can contain para, block, content, and/or other lists.
i'm trying to xform that into a simple UL/LI tree, where each list starts a new UL block and each PARA, BLOCK or CONTENT is a LI within (without changing their relative order or parenting). basically, i'm making a simple HTML preview of the XML doc.
this is my original code, a little recursive template thing:
< xsl:template name="list">
< xsl:for-each select="list">
< xsl:call-template name="listitem" />
< /xsl:for-each>
< /xsl:template>
< xsl:template name="listitem">
< ul class="xsl_list">
< xsl:for-each select="para">
< li class="xsl_list_item">
< xsl:value-of select="para"/>
< xsl:call-template name="list" />
< /li>
< /xsl:for-each>
< xsl:call-template name="list" />
< /ul>
< /xsl:template>
this worked fine for that purpose, but it only pulls out PARA text. now i need to pull out the BLOCK and CONTENT tags, too (in the right order, correctly nested, etc).
so, is there a way to do a boolean match on the < xsl:for-each select="para">, so i could select on PARA or BLOCK or CONTENT ? if not, what's the trick to doing this?
|
|
|
|
|
Yep, just use the | operator: <xsl:for-each select="para|block|content">

ahh, great. thanks.
another question... is there a way to tell which type was matched ? i need to do this because BLOCKs need to be handled slightly differently than PARA, so i want to be able to execute different xsl:call-template's for each type.
nevermind: looks like xsl:when test="self::nodename" is what i needed.

yeah, i tried there (it's usually at the top of Google searches on XSL). but i couldn't find anything that helped.

Unfortunately, it's not organized intuitively. You may be thinking about XSL, but you have to think that if you're writing any XPath statements, you have to go to the XPath section and not the XSL section.

A PDF is supposed to be a read-only document. It is either created from some other document or dynamically via some programming language. Converting it back to some other document is rather difficult! However, there are some commercial applications (and libaries, perhaps) that can convert it back with various degrees of degradation. There are probably some open-source applications or libraries that may help.

It's a long shot and possibly totally unworkable for you but..
If you've any experience C/C++ (maybe VB could do it too) you can get an SDK off Adobe and write a plugin (add on dll file) that could do it for you.
It's about £100 for the SDK and you would need a copy of the full version of Acrobat (using a plugin with the reader requires a special license (around £10,000)).
In the plugin you can access all the text, styles, layout etc.
As I say this may be more trouble than it's worth
All the best
Tom
