Thanks for your attention, I found the reason of this problem yesterday. It's not a technical issue, it just because I made a stupid mistake Unsure | :~

As the code below, I invoke InitReader() function to create and initiate my XML reader. I pass a pointer of ISAXXMLReader into this function, this variable is xReader_Ori.
http://home.pchome.com.tw/funny/alger_lin/Codes/code1.JPG[^]

And in the InitReader(), I pass the inputed ISAXXMLReader pointer into CoCreateInstance() to receive the instance of ISAXXMLReader. However, the xReader parameter is a copy of xReader_Ori, the xReader was represented the ISAXXMLReader's instance after invoke CoCreateInstance(), but the xReader_Ori was not be modified at the same time. So, it cause some error when I called xReader_Ori's parseURL() function, because it's nothing D'Oh! | :doh:

http://home.pchome.com.tw/funny/alger_lin/Codes/code2.JPG[^]

Now, I modified my InitReader()'s definition, I define it as HRESULE InitReader(ISAXXMLReader*& xReader). And it work smoothly now Laugh | :laugh:

Hi,
i was wondering if anyone can help. i am looking to find out how i place data
from a query into my table. However this is being done via xml and xslt. The
data file arrives as xml. the xslt should then take the data and place it into
a table. if there are 6 rows it should draw 6 rows only in the table etc.
does anyone know how this can be done in xslt? and if so how?.

Thanks
Jagdish

Thanks

Help: XML transform with XSL

Hi all,

I'm having a problem with my XSL converting to HTML. I can view all content fine, except the white space is not preserved! I thought whitespace was preserved by default? Confused | :confused:

For example in my XML:

<catalog>
<content>
lines and lines of text
more text
</content>
</catalog>

When transforming I get:

lines and lines of text more text

It's all bunched up...where did the newline characters go?

my XSL contains this:

<xsl:value-of select="content"/>

Any ideas? Thanks.

Thanks for the reply, but I have read that tutorial prior to posting here. I still have an issue with the whitespaces.

Plus W3Schools mentions the following:
Note: Preserving white space is the default setting, so using the <xsl:preserve-space> element is only necessary if the <xsl:strip-space> element is used.

So, by default, I shouldn't have to use the xsl:preserve-space. Although, I have tried either way...and the same result occurred. White-space was not preserved Confused | :confused:

Guys,

Hope I am in the right forum.
What is the difference between the webservice and DLL? Which one is fater? It seems that both of them are the same it depends on how you will use it.
Just a clear explanation since I am new to WEBSERVICE.

I am C# programmer.

well, when you use webservice, you actually call some methods from dll that is somewhere on the web. Communication (transfer of arguments and return value) is done via SOAP - it is XML based format, so you are close to the right forum Smile | :)

Dll on the other hand, is usualy on the same computer as caller. So obviously it is faster... but advantage of Web Service (WS) is that it is platform independent (all you need is to have implementation of SOAP) since communication is basicaly done via XML. And it is web service - it allows you to execute code on distant servers and get results from them.

I hope I said it understandably.

However, there is some study material:

My XmlFile looses its tree hierarchy after saving it

Hello,
I read my xml file into a dataset and set the datasource of a datagrid to access one of the datatables. Problem is that when new rows are added to the datagrid, and I call the WriteXml method, the new rows are added at the root.
Following is an example:
<?xml version="1.0" standalone="yes"?>
<root xmlns="http://tempuri.org/Database.xsd">
<Database>
<Positions>
<Position PositionCode="1" PositionName="Operations Supervisor" Salary="0" />
</Positions>
</Database>
</root>

Then I set the DataSource to of a datagrid to "Position" table and after adding a couple of rows, the saved file looks like:
<?xml version="1.0" standalone="yes"?>
<root xmlns="http://tempuri.org/Database.xsd">
<Database>
<Positions>
<Position PositionCode="1" PositionName="Operations Supervisor" Salary="0" />
</Positions>
</Database>
<Position PositionCode="2" PositionName="Secretary" Salary="0"/>
<Position PositionCode="3" PositionName="LazyGuy" Salary="0"/>
</root>

Note that the new rows were added in "/root" instead of in "root/Database/positions"

Memory leak?

Hi, i'm trying to load an xml document from C++ with:

MSXML::IXMLDOMDocumentPtr pXMLDocument (__uuidof (MSXML:OMDocument)); // main document parsed

hr = pXMLDocument->loadXML (BSTRTemp); /* trying parse string, if success, we have doc object*/

this method uses offensive memory. i have xml files that are about 100MB size.

i feel the function does not clear the memory. anyone an idea?
if i load 3 times the same file, my memory is full.
Confused | :confused:

suggestion? is there a free method or something?

thank you,

lutz

loading a 100mb xml file into the DOM model is going to hurt - you can expect it to take up 10 times the size on disk when its in memory....

so you could use the MSXML 3.0 Sax implementation instead...

XML to Text with "C#"

Hi guys,
I've tried some stuff with XML and XSLT in Java. I had to develop an application that would transform various standards (XML and text) into one overall standard (XML) and then into some other formats (again XML and text). I did it by using Xerces for the text->xml and xml->xml stuff, but it couldn't do the transformations from XML to text.

I know want to do the same thing with "C#" and again I don't know how to transform xml to text.

Does anyone know if it is possible with XSLT? And if yes, how can it be done?

PS: An example of the transformation I need to do would be the following:

<myDoc>
<firstNode>asdf1</firstNode>
<secondNode>asdf2</secondNode>
<thirdNode>
<fourthNode>asdf3</fourthNode>
</thirdNode>
</myDoc>

this would be transformed into something like the following:

firstNode:'asdf1'
secondNode:'asdf2'
thirdNode#fourthNode:'asdf3'

Of course this is only an example, but I think it shows what I want to do.

change in schema file

Hi,

We are making use of SourceGenerator of Castor to generate Java class file from a given schema file and based on the class files we are calling the set functions of the respective classes to populate the corresponding tags in the XML file. We use the marshall function to generate the XML.

We might change the schema file in future, i.e. move some child tags in some different parent tags. for e.g.

excerpt of a schema file.

<empaddress>
<street> Street1
<pincode> 111111

<companyaddress>
<city> XYZ

New schema file:

<empaddress>
<pincode> 111111

<companyaddress>
<street> Street1
<city> XYZ

As it is visible, that <street> tag is moved under <companyaddress> tag. This change triggers change in the names of get/set functions for the corresponding classes and thus generates error during marshalling. Could you please suggest some steps, wherein no code change is required apart from class generation, to accomodate this change in schema file.

Thanks and Regards,
Abdul Qadir

XSLT HTML > XML Transform

I don't see how. Plus your HTML would have to be well formed XML (but that's ok because you surely have XHTML, right?) If the transformation is "1:1", it should be easy to write transfromation (X)HTML->XML based on original one. Maybe it could be even automatized.

Your inverse XSLT may not always be accurate. Mathematically speaking,
f(x)=y, where X is the Xml file, f is the xslt file, and y is the output HTML. But it is also possible f(x2) is also y. So what I'm trying to get is that once you have a "Y", you may not always be able to distinctly identify which input xml produced that result as you may not have preserved all of the input elements/attributes in the output.

You are of course right.

Key phrase in my "solution" is
If the transformation is "1:1"

I had in mind some special cases... Smile | :)

example:

// xml
<article>
<title>My Article</title>
<author>Me</author>
<chapter>Chapter 1</chapter>
<text>My Article</text>
</article>

//html
<html>
<head>
<title>My Article</title>
</head>
<body>
<h1>My Article</h1>
<p>My Article</p>
<center>© Me 2005</center>
</body>
</html>

should be easy no?

I think simple cases as such should not have any problems. Places where you'd run into issues is when Xslt groups/aggregates and/or sorts the data.

Though bit challenging, you'll have to make sure that the formatting does not change when going XML->HTML. If it does, you'll have to take care of the special case.

I'm not sure if the following is a typo. But if it is not, then your conversion from HTML->XML will lose "Chapter 1" value.

yeah damnit, I forgot that Big Grin | :-D

It should be only quick example... But you have the idea... and since none of us know how exactly eggie's XML/HTML/XSLT looks like, we won't get anywhere I guess.
