strugling with Atributed XML parsing.

I have XML in following format
<ORDER>
<HEADER> ... </HEADER>
<LINE> ... <LINE>
<LINE> ... <LINE>
<LINE> ... <LINE>
</ORDER
Can someone suggest how will i parseout such document using XmlSerializer
and attributes.
There can be different amount of lines in different documents.

I have

class clsOrder

{

clsHeader _header;

clsLine [] Lines;

}

How do i specify that <line> goes into Lines array?

Thanks.

George.Hi George,

Thanks for posting in the community!
From your description, you need some suggestions or information on how to
specify the proper XmlAttributes in certian classes so as to use
XmlSerializer to output them and the certain custom class you made contains
an array member of another custom class, yes?
If there is anything I misunderstood, please feel free to let me know.

As for this question, I suggest that you use the "XmlArray" and
XmlArrayItem" attribute to implement the control of the array member within
a certain class's serialization. For example, we can provide the class's
code as below:

public class clsLine
{
public clsLine()
{}

public string Name = "name";
public string Description = "description";
}

public class clsOrder
{
public clsOrder()
{}

[XmlElement("MyHeader")]
public string Header = "header";

[XmlArrayItem(typeof(clsLine),ElementName = "MyLine")]
[XmlArray(ElementName = "MyLines",Namespace = "", IsNullable = true)]
public clsLine[] Lines = null;

}

Notice the two attributes specified in the clsOrder class.
1. the "XmlArray" has specified what name to use for the array member when
the class's instance is serialized, here I specify it as "MyLines", and the
"XmlArrayItem" can be used to specify the array member's item's serialize
options, and when i serialzie a certain clsOrder instance via the following
code:
----------------
XmlSerializer serializer = new XmlSerializer(typeof(clsOrder));

clsOrder odr = new clsOrder();
odr.Header = "Test Order";
clsLine[] lines = new clsLine[5];

for(int i=0;i<lines.Length;i++)
{
clsLine line = new clsLine();
line.Name = "Name" + i.ToString();
line.Description = "Description" + i.ToString();
lines[i] = line;
}

odr.Lines = lines;

TextWriter writer = new StreamWriter("output.xml");
serializer.Serialize(writer,odr);
writer.Close();
------------
The output.xml is like:
----------output.xml--------
<?xml version="1.0" encoding="utf-8"?>
<clsOrder xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<MyHeader>Test Order</MyHeader>
<MyLines>
<MyLine>
<Name>Name0</Name>
<Description>Description0</Description>
</MyLine>
<MyLine>
<Name>Name1</Name>
<Description>Description1</Description>
</MyLine>
<MyLine>
<Name>Name2</Name>
<Description>Description2</Description>
</MyLine>
<MyLine>
<Name>Name3</Name>
<Description>Description3</Description>
</MyLine>
<MyLine>
<Name>Name4</Name>
<Description>Description4</Description>
</MyLine>
</MyLines>
</clsOrder>
----------------

In addition, here is some tech references in MSDN on the how to use and
control the XmlSerializer, I believe they'll be helpful to you:

That is the problem.
Your sample creates following XML
<clsOrder>
<MyHeader>Test Order</MyHeader>
<MyLines>
<MyLine> ..</MyLine>
<MyLine> ..</MyLine>
<MyLine> ..</MyLine>
</MyLines>
</clsOrder
Unfortunately i need following structure.

<clsOrder>
<MyHeader>Test Order</MyHeader>
<MyLine> ..</MyLine>
<MyLine> ..</MyLine>
<MyLine> ..</MyLine>
</clsOrder
Notice there is no <MyLines> tag

I do agree that your structure is more natural and i would not even ask my
question if that was a case. But i stuck with aftermarket standart which was
created by some guys with jumbo heads (joke) and need to be able to parse
that XML

Thanks.
George.

I used the Xml Schema tool(xsd.exe) to automatically generate the schema
and serialize mapping class. To my surprise, the tool generated class
worked. Here is the xml format I used as example to generate class:
<clsOrder>
<MyHeader>Test Order</MyHeader>
<MyLine> dsfsdffd</MyLine>
<MyLine>dsfsdf</MyLine>
<MyLine> fdfdsf</MyLine>
</clsOrder
Then, I used xsd.exe to generate the schema and class ,here is the
generated class:

[System.Xml.Serialization.XmlRootAttribute(Namespac e="",
IsNullable=false)] public class clsOrder {

[System.Xml.Serialization.XmlElementAttribute(Form= System.Xml.Schema.XmlSche
maForm.Unqualified)]
public string MyHeader;

[System.Xml.Serialization.XmlElementAttribute("MyLine",
Form=System.Xml.Schema.XmlSchemaForm.Unqualified, IsNullable=true)]
public clsOrderMyLine[] MyLine;
}

public class clsOrderMyLine {

[System.Xml.Serialization.XmlTextAttribute()]
public string Value;
}

[System.Xml.Serialization.XmlRootAttribute(Namespac e="",
IsNullable=false)] public class NewDataSet {

[System.Xml.Serialization.XmlElementAttribute("clsOrder")]
public clsOrder[] Items;
}

It could serialize and deserialize with the xml format the customer exactly
want. Hope this help!
