In Perl the type of a variable is known at compile time (as indicated by the $ or @ or % prefix). Or did you mean the type of data that a reference is pointing to? In that case, use the ref function.
And BTW look at the Data::Dumper module, it might already do what you want.

Hi,
I'm Ratnakar Pedagani. I'm a starter of XML/XSL and doing coding stuff using java, i.e basic parsing stuff. I want to do my course project and searching for that. The project should implement an XML application that is modeled on a real application and uses Java, database, and XML. I thought of doing project based on weblogs but i got no idea what is weblogs. Can you people suggest me in these lines? If at all you have your own ideas please let me know. I would be grateful to you people if you could let me know as soon as possible. Possible References makes my work much easier.
Thanking you,
Ratnakar Pedagani.

Hi,
I'm working on something which must read the VB.NET project files. Is a schema or DTD availiable for it? I don't want to use CodeModel or automation/extensibilty features.
Thanks

Hi,
I want to retreive the attribute of a specific tag at some level.
Is there any direct method to specify the tag name ,level & attribute name to retreive the value (similar to getElementbyTagName(tagname)?
Thanks

i am using xml file as database in my vc++ project. i want to password protect my xml file so no user can access it.
please help me
|

A XML File is a plain text file... because this cannot be password protected. You can to cryptograph it with the classes of namespace "System.Security.Cryptography" in .Net Framework or CryptoAPI (in Win32 API)
Good Luck!

Hi Gurus!
I have the simplest xml document (d:\\book.xml):
<?xml version="1.0"?>
<Report>
...
</Report>
I've written the small program (inserting XSL reference in the prolog):
Dim xmlDoc,pi,ref
set xmlDoc = CreateObject ("Msxml.DOMDocument")
xmlDoc.async = false
xmlDoc.resolveExternals = false
xmlDoc.load ("d:\\book.xml")
ref="type=""text/xsl"" href=""mysheet.xsl"""
set pi = xmlDoc.createProcessingInstruction("xml-stylesheet",ref)
xmlDoc.insertBefore pi,xmlDoc.childNodes.item(1)
WScript.Echo(xmlDoc.xml)
It works fine!
Next, I tried to do the same using Microsoft Visual C++:
IXMLDOMDocumentPtr XmlDocPtr;
_bstr_t bstrXMLReport(_T("d:\\book.xml");
VARIANT_BOOL vtResult;
HRESULT hr = XmlDocPtr.CreateInstance(MSXML::CLSID_DOMDocument);
if (FAILED(hr))
{
AfxMessageBox("Failed to CreateInstance(CLSID_DOMDocument)");
return;
};
XmlDocPtr->async=FALSE;
XmlDocPtr->resolveExternals=FALSE;
vtResult=XmlDocPtr->load(bstrXMLReport);
if (vtResult == VARIANT_FALSE)
{
AfxMessageBox("Failed to load XML document");
return;
};
IXMLDOMProcessingInstructionPtr pi;
_bstr_t bstrTarget(_T("xml-stylesheet"));
_bstr_t bstrData(_T("type=\"text/xsl\" href=\"mysheet.xsl\""));
pi=XmlDocPtr->createProcessingInstruction(bstrTarget,bstrData);
BSTR qqq;
pi->get_xml(&qqq);
CComVariant varRef;
IXMLDOMNodePtr pFirst,pXMLNodeCur;
XmlDocPtr->childNodes->get_item(1,&pFirst);
varRef=pFirst;
try
{
XmlDocPtr->insertBefore(pi,t);
AfxMessageBox(XmlDocPtr->xml);
}
catch(_com_error &er)
{
TCHAR szErr[MAX_PATH];
memset(szErr,0,sizeof(szErr));
_tcscpy(szErr,(LPCTSTR)er.Description());
AfxMessageBox(szErr);
};
After that, I've got the exception "The parameter is incorrect."
Why? I suspect the incorrect usage of insertBefore method.
What should I do?
Yours sincerely,
Alex Bash

I have a XML File with 32000 records, about 5Mb size. 
How I do to load this (very fast) in Windows Forms DataGrid? 
In help of .Net SDK says what I need use a XMLTextReader, but it is slow for me... 
Thanks for all 
|
|
|
|
|
Have you tried loading the Xml file into a DataSet and assigning it to your grid's DataSource property?
DataSet ds = new DataSet();
ds.ReadXml(<<path to xml file>>);
grid.DataSource = ds;
|
|
|
|
|
What exactly are you wanting to do with this huge XML file? Try loading it into a dataset before loading it into the DataGrid.

Well...
My ISP gives 150 MB space to files and 10 MB of Database (MSDE).
I have a "Holy Bible" database, what haves 6 MB...
How this database is read-only, I think what I can store it in a XML file and load-it when necessary... But this is very slow!!!
Any sugestion?
Thank you very much for your attention 
|

If it's read only, load it into a global application DataSet in the web application startup, that way it'll be around across multiple sessions without the hit from loading a 6MB XML file every time you need to access the "database." You only load it once, when the application starts...
protected void Application_Start(Object sender, EventArgs e)
{
DataSet ds = new DataSet();
ds.Load(Server.MapPath("./db.xml"));
Application.Contents.Add("db") = ds;
}
To get it back, say to load up in a method in aspx code-behind page:
DataSet ds = (DataSet)Application.Contents["db"];

I have an xml document with 3 topic elements: Topic1, Topic2, Topic3
I have an xsl stylesheet that has a topic template. I want to be able to select different combinations of topics using xpath and a parameter.
To select all topics I use this: Content/Topics/Topic
To select just Topic1, I use this: Content/Topics/Topic[@name='Topic1']
I have a param named MatchTopic and I want to select any combination of Topics, say Topic1 and Topic2 or Topic1 and Topic3 or Topic2 and Topic3.
I tried this:
<xsl:apply-templates select="Content/Topics/Topic[$MatchTopic]"/>
with the following param value:
<xsl:param name="MatchTopic">Content/Topics/Topic[@name='Product Updates' or @name='Management']</xsl:param>
and it doesn't work. Nothing I try works.
Is it possible to call this template and select any combination of topics using a parameter?
Thanks in advance.

yes, but you have to use an extension..
msxsl:node-set

I am trying to create an xml file from an xml file using vb.net and XmlTransform.
My xsl file has this line
xsl:output method="xml" version="1.0" encoding="UTF-8" cdata-section-elements="Column"
I want to wrap the data in the node Column in CDATA tags. This works in vbScript and tesing using XML Spy but in the asp.net page using XmlTransform the node does not get wrapped in CDATA Tags.
Any help would be great I am in a bind.

I'am quite new to XML in .NET and would appreciate some advice on the correct way to iterate through an XML document I have created like:
[XML DOC]
[OuterList]
[ListItem image="C:\pic1.wmf"]
[InnerList]
[Item Atr1="ABC" Atr2="DEF" Atr3="GHI"/]
[Item Atr1="123" Atr2="456" Atr3="789"/]
[/InnerList]
[/ListItem]
[ListItem image="C\pic2.wmf"/]
[InnerList]
[Item Atr1="ZYZ" Atr2="WVU" Atr3="TSR"/]
[/InnerList]
[/ListItem]
[/OuterList]
- note I have replaced the XML tags with []
I would only want to go to a specific item in the outerlist, and then read each item in its innerlist.
