Hi all,
I'm trying to read a file wuth C#. The file contains the following:
<?xml version="1.0" encoding="utf-8" ?>
<voice_config>
<voice_type>Microsoft Mary</voice_type>
<voice_volume>100</voice_volume>
<voice_rate>0</voice_rate>
</voice_config>
and the code to read is:
voice_reader.Read();
voice_reader.ReadStartElement("voice_config");
voice_reader.ReadStartElement("voice_type");
m_voice = voice_reader.ReadString();
voice_reader.ReadEndElement();
voice_reader.ReadStartElement("voice_volume");
m_volume = voice_reader.ReadContentAsInt();
voice_reader.ReadEndElement();
voice_reader.ReadStartElement("voice_rate");
m_rate = voice_reader.ReadContentAsInt();
voice_reader.ReadEndElement();
voice_reader.ReadEndElement();
I'm getting the following exception thrown:
Exception : Unexpected XML Declaration. The XML Declaration should be the first node in the document, and no whitespace characters are allowed to appear before it, Line 1 position 100

try
{

while (voice_reader.Read())
{
if (voice_reader.NodeType == XmlNodeType.Element)
{
switch (voice_reader.Name)
{
case "voice_config":
break;
case "voice_type":
Console.WriteLine(voice_reader.ReadString());
break;
case "voice_volume":
Console.WriteLine(voice_reader.ReadString());

}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
if (voice_reader != null && voice_reader.ReadState != ReadState.Closed)
{
voice_reader.Close();
}
}
}

Got it now. Knew it would be simple.

Hi,
I'm designing a framework for an enterprise application.
I have done this earlier but I used to define model (properties, methods, events…) inside framework itself.
Programmer writes codes based on the model defined in framework, in other words interface that is created inside framework later implemented by the programmer.
Now I would like to isolate model definition from framework and define the model in a separate XML file so that framework will extract model definition from XML file dynamically.
How do I achieve this ?
Advance Thanks !
Regards,
aB

Using "Reflection" might be an option.

Hi to everybody,
I need some help to convert a XML DataSet to an Excel file. I actually using this code:
Private Sub TransformXML(ByVal xmlDoc As XmlDataDocument, _
ByVal strXSLPath As String, _
ByVal strSavePath As String)
Dim xt As New XslCompiledTransform
Dim tw As XmlTextWriter
tw = New XmlTextWriter(strSavePath, System.Text.Encoding.UTF8)
tw.Formatting = Formatting.Indented
tw.Indentation = 3
tw.WriteStartDocument()
xt.Load(My.Application.Info.DirectoryPath & strXSLPath)
xt.Transform(xmlDoc, Nothing, tw)
tw.Close()
End Sub
The XSLT follow here  :
<xsl:stylesheet version="1.0"
xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:user="urn:my-scripts"
xmlns ="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" >
<xsl:template match="/">
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns ="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:html="http://www.w3.org/TR/REC-html40">
<xsl:apply-templates/>
</Workbook>
</xsl:template>
<xsl:template match="/*">
<Worksheet>
<xsl:attribute name="ss:Name">
<xsl:value-of select="local-name(/*/*)"/>
</xsl:attribute>
<Table x:FullColumns="1" x:FullRows="1">
<Row>
<xsl:for-each select="*[position() = 1]/*">
<Cell>
<Data ss:Type="String">
<xsl:value-of select="local-name()"/>
</Data>
</Cell>
</xsl:for-each>
</Row>
<xsl:apply-templates/>
</Table>
</Worksheet>
</xsl:template>
<xsl:template match="/*/*">
<Row>
<xsl:apply-templates/>
</Row>
</xsl:template>
<xsl:template match="/*/*/*">
<Cell>
<Data ss:Type="String">
<xsl:value-of select="."/>
</Data>
</Cell>
</xsl:template>
</xsl:stylesheet>
The problem is that the XSLT must be generic because the DataSet it's always different. I would like to retrieve the datatype from the DataSet schema and create the Excel file properly. The XSLT attached perform only a simple transformation.
Can anyone help me with XSLT and kindly provide a better implementation?
Thanks in advance to anyone will replay

Thanks for your reply, but I want to convert my XML to XLS using XSLT.
Here an example of what I want to have!
http://support.microsoft.com/?kbid=319180
The code posted already work, I need only a better implementation of the stylesheet...
Thanks again

Im new to using Xml with C#. I have been hacking around at one section for a day now and can't get it to work at all. Rather than confuse you with my shambles code, I will jsut explain the concept. Im also slightly confussed, or misslead with my understanding of the type deffinitions, and their methods for subtrees.
<code>
XML...
<Root>
<MajorKey att="MAJattribute1">
<MinorKey att="MINattribute1">
<Value>value1</Value>
</MinorKey>
<MinorKey att="MINattribute2">
<Value>value2</value>
</MinorKey>
</MajorKey>
<MajorKey att="MAJattribute2">
<MinorKey att="MINattribute3">
<Value>value3</Value>
</MinorKey>
<MinorKey att="MINattribute4">
<Value>value4</value>
</MinorKey>
</MajorKey>
</Root>
</code>
Im having trouble getting it to create a nodelist to children underneath a node based on it's att (attribute) value. Also, I want to extract that attribute value into a string so "MAJattribute1" would gointo a string inside the loop for that node treversal.
Any help, or suggestions.
I have spent hours and hours reading, and cant seem to find anything to pinpoint this...only ever creating attributes indide a single node, not looping through based on the attribute value.
IM GETTING STRESSED
Regards
njc

Hi,
VS 2005 / C#
Simple situation: A DataTable with some columns and rows added. But when using the WriteXML method to create an XML file from this table it gives me the following output:
<?xml version="1.0" encoding="utf-8"?>
<DocumentElement>
<Batch_Table>
<Height>18</Height>
<Width>75</Width>
<Program>1</Program>
<Length1Min>18</Length1Min>
<Length1Max>60</Length1Max>
<Price1>1000</Price1>
</Batch_Table>
<Batch_Table>
<Height>25</Height>
<Width>125</Width>
<Program>2</Program>
<Length1Min>12</Length1Min>
<Length1Max>40</Length1Max>
<Price1>1200</Price1>
<Length2Min>40</Length2Min>
<Length2Max>60</Length2Max>
<Price2>1300</Price2>
</Batch_Table>
...and so on. The problem is that each row/record of the table is named as the TABLE (which is called "Batch_Table"). This is wrong! How can I fix this?
Thanks.

Hi,
I am having an XML file which has two elments id & StartDate, Iam using Visual C# > XMLTextReader Object "reader" to read this file, if the nodetype is text and the elementname is startdate then write the startdate by converting it. If you see the below code hope every thing gets clear
Insted of getting the value I want to search if the XmlNodeType is text then I want to get the datatype (i.e. date or string or int32 etc.) of the element insted of the value
System.IO.Stream objStream = new System.IO.MemoryStream();
DataSet objDs = new DataSet();
objDs = getData();
XmlTextReader reader = new XmlTextReader(objDs.GetXml(), XmlNodeType.Element, null) ;
Response.ContentType = "text/xml";
XmlTextWriter writer = new XmlTextWriter(Response.OutputStream, System.Text.Encoding.UTF8);
writer.Indentation = 4;
writer.WriteStartDocument();
string elementName = "";
while(reader.Read())
{
switch(reader.NodeType)
{
case XmlNodeType.Element:
writer.WriteStartElement(reader.Name);
elementName = reader.Name;
break;
// In the below case I have a problem I want to get the datatype of the node insted of the data
case XmlNodeType.Text:
if(elementName == "StartDate")
writer.WriteString(XmlConvert.ToDateTime(reader.Value).ToString());
else
writer.WriteString(reader.Value);
break;
case XmlNodeType.EndElement:
writer.WriteEndElement();
break;
}
|
|
|
|
|
The type of the element is defined in the schemas, there is no way to get this information from the xml document alone.

Hi,
I wonder if anyone can offer some advice on the best way to accomplish this:
I have an existing asp.net app that displays products from a catalogue, data stored in access. My friend has provided an xml feed from their database so that I can incorporate their data into my app, without the need to duplicate the data. How would I go about building a feed mechanism where by I can display their data whenever a user loads my app?
I would guess this is a common requirement.
Many Thanks
Kieran
