Hi I am planning to implement a custom version control system. Is there anyway to represent physical directory structure in database? Or should I represent them using 'tree' data structure? If using tree data structure, how can I save the contents of tree to an external file?? thanks fadi

I got one more query. Will it be possible by embedding script in xslt? I tried the following way Xslt file

?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
xmlns:user="urn:myscripts"

<xsl:output method="xml" indent="yes"/>

<msxsl:script language="C#" implements-prefix="user">
<![CDATA[
public void SaveOutput(string fileName)
{

  System.IO.TextWriter t = new System.IO.StreamWriter(fileName);
  t.Write("got it");
  t.Flush();
}
\]\]>

</msxsl:script>

<xsl:template match="@* | node()">
<xsl:value-of select="user:SaveOutput('d:\testing.txt')"/>

</xsl:template>

</xsl:stylesheet>

My C# code is

    private void ScriptTest()
    {
        XsltSettings settings = new XsltSettings();
        settings.EnableScript = true;

        XslCompiledTransform trs = new XslCompiledTransform();
        trs.Load("Custom.xslt", settings, new XmlUrlResolver());
        StreamWriter writer = new StreamWriter(@"e:\\samples.txt");
        trs.Transform(@"E:\\\\9.xml", null, writer);

        writer.Flush();
        writer.Close();
    }

But when I run the code, I get en error like IOException unhandled - The device is not ready Thank you Fadi

Thank you Stuart But can you clarify some more things? My xml file is

<?xml version="1.0" encoding="utf-8" ?>
<bookstore>

My xslt file is

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:output="urn:output">

<xsl:template match="bookstore">
<bookstore>
<xsl:for-each select="book">
<book>
<xsl:copy-of select="node()"/>
<new-price>
<xsl:value-of select="output:SaveOutput(@genre, node())"/>
</new-price>
</book>
</xsl:for-each>
</bookstore>
</xsl:template>
</xsl:stylesheet>

C# code goes like

private void ExtensionTest()
{
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load("extension.xslt");
XsltArgumentList xslArg = new XsltArgumentList();

        OutputSaver obj = new OutputSaver();
        xslArg.AddExtensionObject("urn:output", obj);
        using (XmlWriter w = XmlWriter.Create("output.xml"))
        {
            xslt.Transform("books.xml", xslArg, w);
        }

}
public class OutputSaver
{
public void SaveOutput(string fileName, string node)
{
StreamWriter s = new StreamWriter(fileName);
s.Write(node);
s.Flush();
}
}

Now I have 2 issues * How to pass the xslt node content to SaveOutput

Hi I am doing a code generation app. using .Net 3.5. I wish to know if it is possible to generate multiple code files from a single xslt file. I know that it can be accomplished in XSLT 2.0 using result-document tag. Is it possible using XSLT 1.0 ? Thanks Fadi

I had tried putting spaces. but it didn't work out. W.r.t. ur reply, i tried putting quotes for the strings with spaces and it worked fine..... Thank you very much Luc

Hi Hi I am using System.Diagonostics.Process.Start for staring a new process. If I want to pass mulitple marameters with different switches, how can I do it? Thanks Fadi

you can use Substring method instead of Split method. find the index of '=' character using IndexOf method and then pass this index + 1 as the parameter of Substring method.

Thank you very much

Thank you very much Stuart.. It really worked... Hats off to u

Hi I have a class named Item. It has the public members, 'Name' and 'Subitems'. I have declared a list of Items (List itemList). Now I want to write a function which accepts a new 'Item' and decides if itemList already has the 'Item'. I tried writing a function like bool Check(Item p) { return itemList.Exists(m=> m.Name == p.Name && m.SubItems.SequenceEqual(p.SubItems)); } Here the issue is, default comparing is done for SequenceEqual method. I want to compare SubItems using the Name property of the SubItems. How can I modify my function so that SequenceEqual works based on the NameProperty of the subitem? Thank you Fadi

Hi I am writing a code generation app using xslt. My purpose is to check if any two nodes of the same parent node, have the same attribute value. If so I want to append a number sequence in the ouput code, so that there is no duplication. For example ------------- if xml file is like <code> <methods> <method name="first"> <method name="first"> <method name="second"> <method name="third"> </methods></code> I want the output to be ------------- void first1() {} void first2() {} void second() {} void third() {} Note: there is no number sequence attached to function name if it is not duplicated. How to write XSLT to achieve this? Thank you Fadi

Thank you very much for the info. But I wish to know one more thing. How huge applications like encyclopedias stores information? If they store in database, how is it possible to install them, without having the database server in the system?

hi, I have a program which does some operations with database.(Single tier architecture) I will sometimes have to move the application to other systems having the database. In order to make the database connection parameters configurable, i am storing the params such as username, password etc. in an xml file. Is it the correct way to handle the situation? If so will it be safe to store the database password in an xml file? how can i solve the issue? If the application is meant for ordinary users(who may not have the database files), how can we approach the problem? Cconfiguration file will not be easy for him to edit no? Thank you Fadi

thank you very much George.... it is really helpful @ this situation... led, lemme thank u also for ur efforts.(but you should understand the seriousness of misguiding someone(and all who read the post) with respect to a temporary output. there were errors in my xslt. you didn't even point out that. What if I had blindly believed you!!!!!)

Led, You argued like "A Web Browser is only going to display HTML." Was it a blind response? When you get time, make an html file, open it in edit mode and paste plain text in that. Try viewing in a browser and you can still see the plain text (which was written without html markups). Now try creating another .html file and paste some xml conent in that. Try viewing in a browser and you can still see the innertext of html nodes in a non formatted manner. Can you pls. explain the reason for this w.r.t. your argument?? Also can you try the default xml given in http://www.w3schools.com/xsl/tryxslt.asp?xmlfile=cdcatalog&xsltfile=cdcatalog[^]. Just change the xslt content as follows ---------------------------- <?xml version="1.0" encoding="ISO-8859-1"?> <!-- Edited by XMLSpy® --> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:template match="/"> <xsl:for-each select="catalog/cd"> <xsl:value-of select="title"/> <xsl:value-of select="artist"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> ---------------------------- Now can you pls explain why the output is displayed in the browser even if it is in text format?? If you find a solution, can you pls. explain what is wrong with my code in the first post?? Sorry for disturbing you again It would be nice of you, if you can convince me with a good answer Thanks Fadi

Thanks alot for the effective criticism. I overestimated (mistook) like the system had the facility to convert xml/text formats to html. Anyway "alerted hereafter" :) thanks Fadi

You can paste the xml and xslt I gave in w3schools' xslt tester. I have pasted the link below http://www.w3schools.com/xsl/tryxslt.asp?xmlfile=cdcatalog&xsltfile=cdcatalog[^] thanks fadi

Hi... when I apply xsl transformation, no output is obtained. Can anyone help me? My xml file is --------------------- <?xml version="1.0" encoding="utf-8"?> <Data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <MySpace>Testing</MySpace> </Data> --------------------- My xslt file is ----------------------- <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text" indent="yes"/> <xsl:template match="/"> <value-of select="MySpace"/> </xsl:template> </xsl:stylesheet> ----------------------- Thanks Fadi

hi I am having a treeview in the left, a list view in the right and a refresh button. Treeview shows year,month and dates while listview shows the logs for the current date selected date. While pressing refresh button, I have to update both treeview and listview from the latest data in dataset. How can I retain the selected node of the treeview when it is updated. thanks Fadi
