Re: .NET newbie has question RE: XmlTextWriter - XML / XSL Discussion Boards

Hello,

I am trying to read a XML file which has japanese characters -- The XMPL processor I am using is LIBXML2.

The XML file I am trying to read is as follows:
<><<response result="failure" loglevel="5" cname="recognizeversion" csever="10.5" addn="abc" focusbrowser="true" iid="1480" cse="SolidWorks" ver="10.5">><<info>><<reason>>ãƒãƒ¼ã‚¸ãƒ§ãƒ³èªè˜ã¯ãƒ¦ãƒ¼ã‚¶ã«ã‚ˆã£ã¦ãƒãƒ£ãƒ³ã‚»ãƒ«ã•ã‚Œã¾ã—ãŸ<><><>

Note, that the junk characters above are the japanese characters. If I save this file and open in IE then the characters are displayed in Japanese.

I using the following code to read the japanese character as contained in the <response>.<info>.<reason> section.

xmlChar * xmlStr = xmlNodeListGetString(doc, cur->xmlChildrenNode, 1);

CString xx = xmlStr;

AfxMessageBox(xx);

The above messagebox shows junk characters. I want it to display it as is visible in the IE.

Where am I doing the things wrong.
Thanks in advance.

Amol

Are you using a Unicode build? If not, CString will interpret xmlStr as ASCII characters, resulting in what you've got there.
Even if you've got a Unicode build...you're not telling anything that xmlStr is UTF-8...

You can verify that libxml is reading the characters correctly by using xmllint (it converts the Japanese characters to numeric entities) and looking up the character codes in charmap.

In order to convert the UTF-8 that libxml gives you to (say) UTF-16, you can use code like this:

<br />
const int WIDE_COUNT = 1024;<br />
wchar_t wide[WIDE_COUNT] = {0};<br />
int inLen = lstrlenA(LPCSTR(xmlStr));<br />
int outLen = WIDE_COUNT;<br />
xmlCharEncodingHandlerPtr handler = xmlGetCharEncodingHandler(XML_CHAR_ENCODING_UTF16LE);<br />
         int nOut = handler->output((xmlChar*)wide, &outLen, xmlStr, &inLen);<br />

This puts the same UTF-16 values in the string wide that xmllint displays as numerical entities.

As to displaying the characters in a message box - I'm afraid I don't know - it'll be character sets again, or fonts, though!!!

Hie...
I have a login page using XML to store my UserEmail and UserPass.
Now, I want to verify with the XML, if user type a correct UserEmail and UserPass, then login proceed; if not, message text: This is an invalid Account.
Please help?
Thanks.

This is my first .Net application so i appologise for my stupidity. What the application is, is a navigation control for an intranet that a colleage has been building. It uses a .Net component (ASP.NET DHTML Menu)
http://www.apnsoft.com/?L=E&LM=Menu_Main&MD=Menu_Features

which uses strong xml.

My task has been to create an app to edit this xml in .NET. So i have set about learning all i can about how (the #uck) to do this ... here is a little drawing of what i have come up with:

www.elevatordigital.com/images/myplan.gif

My question is is it possible to take the stream created with the SqlCommandClass directly to the xml file main.xml?

Any help with this would be greatly appreciated. Im slightly out of my depth with this project so if anyone thinks there is a better way of achieving this i would love to hear about it.

Cheers

I have created a datagrid to edit the SQL database and a page which has the following code onLoad:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

' Load proper XML from SQL Server
Dim strConn As String = "My Connection String is Here"
' Define the XML command
Dim cmd As SqlXmlCommand = New SqlXmlCommand(strConn)
' Set up a SqlXmlCommand from a xml template using FOR XML EXPLICIT
cmd.CommandType = SqlXmlCommandType.Template
cmd.CommandText = Server.MapPath(@"template.xml");
cmd.BasePath = Server.MapPath(@"\");
' Specify a root element for the result
cmd.RootTag = "menu"
' Read the XML into an XmlReader
Dim xr As XmlReader = _
cmd.ExecuteXmlReader()
' Transfer it to an XmlDOcument
Dim xd As XmlDocument = New XmlDocument
xd.Load(xr)
xr.Close()
' Get a Transform ready
Dim xslt As XslTransform = New XslTransform
xslt.Load("main.xslt")
' Use the transform to rewrite it
Dim ms As MemoryStream = New MemoryStream
xslt.Transform(xd, Nothing, ms)

Dim mywriter As System.Xml.XmlTextWriter

mywriter = New System.Xml.XmlTextWriter("main.xml", Nothing)

With mywriter
.WriteStartDocument()
.WriteString(ms)
.WriteEndElement()

.WriteEndDocument()
End With

mywriter.Flush()
mywriter.Close()

End Sub

But i have got syntax errors at these elements:

1. cmd.CommandText = Server.MapPath(@"template.xml");
2. cmd.BasePath = Server.MapPath(@"\");

3. xslt.Transform(xd, Nothing, ms) - I think this is to do with the memory stream

4. .WriteString(ms) - I think i need to convert the memory steam to a string using Streamreader

If anyone can help me with these problem that would be a grea help

Cheers

hi,
yeah I know, too late for help. And i am not even really helpful... Frown | :(

a) since I hate coding in this *pseudocode* (I mean VB) no way how to help with syntax errors
b) why not to try language begining with "C"? Wink | ;)

c) how is menu stored in DB? adding separators using xslt sounds little strange to me...
d) IMO there is no way how to directly store sql query result into xml file, since XmlReader is for reading, not for writing. You may want to create e.g XmlDocument and then save it with XmlDocument.Save() to file. You can even insert <separator> tags with XmlDocument.InsertAfter() method. Look for more at msdn.com.
e) I am quite tired so in case I am writing bulls*it, sry.

Never forget: "Stay kul and happy" (I.A.)

Worried,

I have been working with XML for a while and quite often, I need to write navigation functions to search for a particular DOM model, such as find a book with a particular keyword but the publisher has to be somePublishName, plus the price of the book cannot be hight than $50.00, etc. The code to finish this task is somehow quite alike and tedious, I was just wondering if there is any tool to help on this part? For example, what about the TreeWalker thing with a NodeFilter? anyone heard of this and had some experience with this? Basically the searching in the XML file is very tedious and somewhat repeatable, any tools for this.

If u r looking for tools, u can use xmlspy.
I guess there is a free version also.

cool man

Hi,

I have a XML file which needs to be first validated using a DTD and then parsed to get values & properties associated with tags.

I am using Visual Studio's VC++ 6.0 to write my code. Is anyone aware of any reference or tutorial which would help me learn the same.

Thanks You!!

Regards

Have a look at http://xml.apache.org/xerces-c/index.html

store your internet favourites online - www.my-faves.co.uk

this is a piece of the xsl i use:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml">
<xsl:output omit-xml-declaration="no" method="xml" indent="yes" doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" />

...

<input type="hidden" name="projectcode">
<xsl:attribute name="value">
<xsl:value-of select="../PROJECTCODE"/>
</xsl:attribute>
</input>

...

but when i render the xml using System.Xml.Xsl.XslTransform, the result is not valid xhtml. The hidden input is generated as:
<input type="hidden" name="projectcode" value="123"></input>

in stead of:
<input type="hidden" name="projectcode" value="123" />

does anyone have any idea what i am doing wrong??

Use the inline syntax for your attribute then you can have a closed tag element.

Thanks Chris!!

That did the trick!! Big Grin | :-D

Hello all,

I am processing an XML file section appropriately (Individuals) . I have added elements (the Numbers section) to the XML File.

Below is the XML File Layout:

<Metrics>
<Numbers>
<Possible>13</Possible>
<Fail>0</Fail>
<Pass>7</Pass>
<Blocked>0</Blocked>
<NotRun>2</NotRun>
<TestBridgeID>43</TestBridgeID>
<VersionID>14</VersionID>
<Verified>0</Verified>
<Errors>4</Errors>
<Deleted>0</Deleted>
<RunDate>7/7/2004</RunDate>

</Numbers>
<Individuals>
<MultiLevelID>820</MultiLevelID>
<UIValues>
<Tab>Finishing</Tab>
<Control>Landscape</Control>
<Setting>ON</Setting>
<Disposition>1</Disposition>
<Reason>12</Reason>
</UIValues>
<UIValues>
<Tab>Finishing</Tab>
<Control>Landscape</Control>
<Setting>ON</Setting>
<Disposition>1</Disposition>
<Reason>12</Reason>
</UIValues>
</Individuals>
<Individuals>
etc. etc. etc.

Here is my code for processing the Individuals section.

private void ReadIndividualUI()
{
//Create a resolver with the necessary credentials.
XmlUrlResolver resolver = new XmlUrlResolver();
NetworkCredential nc = new NetworkCredential(ConfigurationSettings.AppSettings ["SecureLogin"], ConfigurationSettings.AppSettings["SecurePassword"]);
resolver.Credentials = nc;

// Get a Stream object containing the XML file.
Uri myUri = new Uri("http://Benningfield1/DataSetTest/SwattReporta.xml");

Stream s = (Stream)resolver.GetEntity(myUri, null, typeof(Stream));

// Construct a reader using the Stream object.
XmlTextReader xmlReader = new XmlTextReader(s);

//Process XML File accordingly
while(xmlReader.Read())
{
//Perform appropriate processing
}

Here is my pseudocode for what I need to do next.

Go To The Numbers element
Pull all values (from Possible element, FAil element etc.) into a memory storage area
Then process values accordingly

What is the best way to mesh what I want to do in Pseudocode with the current ReadIndividualUI() method functionality?

Can any body plz favor me with the regular expression of Xml document?

Hi Seekhtar
I really cann't understand your request ..
what do u mean by "regular expression of Xml document" ?
May be I could help u Wink | ;)

Good Luck

Although there does not seem to be too much traffic in here I'll give it a try anyway...

I would like to be able to merge two XML documents, in such a manner that one will override the other. I.e., there will be a "global" XML file that contains some generic data, and then a "local" XML file that contains data that overrides data found in the global file. The local file does not have to contain the exact same number of nodes as the global one, i.e. it may only contain the nodes that we are interested in overriding.

You may ask yourself "how can this be helpful?", one example could be a global file that contains various settings that are used in an application, including text strings that will be visible to the user, and then a local file that contains translation of these visible text strings to some other languge, but otherwise does not change the settings/data in any way. In this way it will be easy to localise this file (we might want to be able to translate into many languages) without having to maintain multiple copies of the settings file - one for each language.

What I'm curious about is if there is a simple way to accomplish this through any known tools. The overhead should preferably be small, i.e. I don't want to be forced to install some massive Java libraries for this task alone Smile | :)

. The code we're currently using to load/save XML files uses the Microsoft XML Parser so anything that's available through that tool is OK. I'm also willing to take a look at some .NET components if they do the job nicely, since this code will be used in an environment that ensures that the .NET framework has been installed.

Mind you that there are some obstacles on the way, for instance if the files in question were to store a list of books (classic example) and we would like to display the name of each book in the correct language, then we could create two files:

global.xml:

<books>
<book id="1">
<name>Some book</name>
<author>John Doe</author>
</book>
<book id="2">
<name>Another book</name>
<author>Susanne Smith</author>
</book>
</books>

local.xml ( book names have been translated into Icelandic Smile | :)

) :

<books>
<book id="1">
<name>Einhver bók</name>
</book>
<book id="2">
<name>Einhver önnur bók</name>
</book>
</books>

where the local.xml file does not want to mess with the author names, and it must override the correct bookname based on the id's. Note that under some circumstances, xml nodes equivalent to the <book> node might contain more attributes (not just the "id" attribute), and the unique attribute isn't necessarily called "id".

So does anyone have a *simple* solution to this problem? Any pointers would be very much welcome.

Best regards,
Daniel

Yes it is possible, I have worked on many a project where xml files are merged.

Unfortunatly I don't think there is any generic tool that will just do it for you, they way I have seen it done, is that the global xml file is loaded into the dom using MSXML, and the local file is loaded into a seperate dom.

Then for each node in the local file, a select is run against the global dom, to see if that node already exists. If it does the value is either replaced if the node does not exist then it is added into the dom.

All of this can be done using microsofts MSXML, just means writing some code yourself.

Thanks for your reply, writing code that uses the MSXML DOM is exactly what I have done, I was only curious if maybe I had reinvented the wheel Smile | :)

Wenn ist das Nunstück git und Slotermeyer? Ja! Beierhund das oder die Flipperwaldt gersput!

The merging of two xml documents can be more easily and elegantly performed by using xslt. Here is a link that implements the same beautifully.
