my code gives me error : "'.', hexadecimal value 0x00, is an invalid character. Line 2, position 1."
string FileName = "20110606 100419 ServerForShop 1.xml";
string root = Server.MapPath("~/Include/Xml Files/Patch/");
var custs = from c in XElement.Load(root + FileName).Elements("Update")
select c;
I want to read and execute command a big xml file it is about 350MB how I can read it ? here is my xml file structure :
<?xml version="1.0" encoding="utf-8"?>
<Update>
<Object Name="Good">
<Insert Table="Good">
<Field Name="GoodCode" Value="1" Type="Integer" />
<Field Name="GoodUserCode" Value="" Type="String" />
.
.
.
</Insert>
</Object>
</Update>
I would recommend looking here for some samples http://support.microsoft.com/kb/307548
and perhaps here How does one parse XML files?

I have two XML Files ,the first one is and Named as XMLTemplate
<DataSources>
<DataSource Name="XXXX">
</DataSource>
<DataSource Name="ABC">
</DataSource>
</DataSources>
<DataSets>
<DataSet Name="abc">
<Query>
</Query>
<ReportSections>
</ReportSections>
and the second xml file is named as XMLGenrated,
<Fields>
<Field >
</Field>
</Fields>
and I need the Output as,
<DataSource Name="XXXX">
</DataSource>
<DataSource Name="ABC">
</DataSource>
</DataSources>
<DataSets>
<DataSet Name="abc">
<Query>
<Fields>
<Field >
</Field>
</Fields>
</Query>
<ReportSections>
</ReportSections>
Both the Files are in .XML Extension and I dont know how to find the node by its Name Can anyone help me out.
I tried this,
XElement xFileRoot = XElement.Load(XMLTemplate.xml);
XElement xFileChild = XElement.Load(XMLGenerated.xml);
xFileRoot.Add(xFileChild);
xFileRoot.Save(file1.xml);
but the XML adds below the XMLTemplate I dont know how to insert at particular node.
Find the node using Linq to XML and Replace its contents
XElement xFileRoot = XElement.Load(XMLTemplate.xml);
XElement xFileChild = XElement.Load(XMLGenerated.xml);
var queryNode = xFileRoot.Element("Query");
queryNode.ReplaceWith(xFileChild) ;
Based on on this answer - How can I update/replace an element of an XElement from a string?
Be aware that you sample XML files contain multiple root nodes, and that if you need to keep the <Query> node you need to change this.
I want to set the length to MAX for one of my XML fields.
XML Code:
<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RECORD>
<FIELD ID="1" xsi:type="CharFixed" LENGTH="3" />
<FIELD ID="2" xsi:type="CharFixed" LENGTH="MAXLENGTH" />
<FIELD ID="3" xsi:type="CharFixed" LENGTH="10" />
<FIELD ID="4" xsi:type="CharFixed" LENGTH="8" />
</RECORD>
<ROW>
<COLUMN SOURCE="1" NAME="Field1" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="2" NAME="Field2" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="3" NAME="Field3" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="4" NAME="Field4" xsi:type="SQLNVARCHAR"/>
</ROW>
</BCPFORMAT>
But 'MAXLENGTH' does not seem to work.
Error message:
bad value MAXLENGTH for attribute "LENGTH"
Any suggestions on how to put the LENGTH to maximum ?
The length of a string is limited to 4000 (nchar) or 8000 (char) type. There is no max length-constant - AFAIC
Refer to this, "Field Attributes"
If you look up the schema meta-data just as SQL Server does, you can follow this link
http://schemas.microsoft.com/sqlserver/2004/bulkload/format/bulkloadschema.xsd
to find this
<xsd:attribute name="LENGTH" type="xsd:positiveInteger" use="required"/>
[...]
<xsd:attribute name="MAX_LENGTH" type="xsd:positiveInteger" use="optional"/>
So the length is required while max_length seems to be optional, but if you specify it, it must be a positive integer.
I have this following xsd file. I try to generate class using vs command line like:
command line word = xsd test.xsd /c
"Data at the root level is invalid. Line2, position1.". I am not sure why I having this error. Please advise.

To generate code:
Edit the example file so that the & character is encoded. Specifically, swap it for &
Rename the file to test.xml
Run xsd.exe test.xml to generate a schema e.g. test.xsd
Run xsd.exe /c test.xsd to generate classes from the schema
EDIT: This worked fine for me. Here's the contents of my test.xml:

I have an ever increasing number of BCP (t-sql) format files in XML that I need to read. I create the xsd file using xsd.exe and a number of BCP format files and attempt to read the xml file as an object. But it fails like this:
Unhandled Exception: System.InvalidOperationException: There is an error in XMLdocument (4, 6). ---> System.InvalidOperationException: The specified type was not recognized: name='CharTerm', namespace='http://schemas.microsoft.com/sqlserver/2004/bulkload/format', at .
The XML file is like this:
<?xml version="1.0" encoding="utf-8" ?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<FIELD ID="4" xsi:type="CharTerm" TERMINATOR=";" MAX_LENGTH="20"/>
<FIELD ID="5" xsi:type="CharTerm" TERMINATOR="\r\n" MAX_LENGTH="16"/>
</RECORD>

<COLUMN SOURCE="4" NAME="col4" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="5" NAME="col5" xsi:type="SQLFLT4"/>
</ROW>
</BCPFORMAT>
I read the XML file like this:
FileStream fs = File.OpenRead(formatFileName);
XmlSerializer serializer = new XmlSerializer(typeof(FormatSchemasXml.BCPFORMAT));
FormatSchemasXml.BCPFORMAT bcp_format = (FormatSchemasXml.BCPFORMAT)serializer.Deserialize(fs);
fs.Close();
The external xmlns reference does not seem to be used. I have searched a lot of documentation, but failed at seeing how I can fix this. Preferably without having to modify the BCP XML format files (I'd like to use them as is).
Suggestions?
I want to Upload File on Sharepoint and while apploading only i want to add all properties of Uploaded Document.
We get ID field only when Document is uploaded on Sharepoint.
Is there any other way to Update List without passing ID Field.
Example:
<Batch OnError="Continue" ListVersion="1"
ViewName="270C0508-A54F-4387-8AD0-49686D685EB2">
<Method ID="1" Cmd="Update">
<Field Name="ID">4<Field>
<Field Name="Field_Name">Value</Field>
</Method>
<Method ID="2" Cmd="Update">
<Field Name="ID" >6</Field>
<Field Name="Field_Name">Value</Field>
</Method>
</Batch>

**** I am using Sharepoint Web Services.And Uploading Document in Chunks.****
This is not possible. First the file should complete uploading, then it will have properties that can be set! (otherwise properties may be set for non-existing files, in case that the file fails to upload.)
