在XML序列化期间删除命名空间

Question

鉴于此通用序列化代码:

public virtual string Serialize(System.Text.Encoding encoding)
{
 System.IO.StreamReader streamReader = null;
 System.IO.MemoryStream memoryStream = null;

 memoryStream = new System.IO.MemoryStream();
 System.Xml.XmlWriterSettings xmlWriterSettings = new System.Xml.XmlWriterSettings();
 xmlWriterSettings.Encoding = encoding;
 System.Xml.XmlWriter xmlWriter = XmlWriter.Create(memoryStream, xmlWriterSettings);
 Serializer.Serialize(xmlWriter, this);
 memoryStream.Seek(0, System.IO.SeekOrigin.Begin);
 streamReader = new System.IO.StreamReader(memoryStream);
 return streamReader.ReadToEnd();
}

和这个对象(来自xsd2code):

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.225")]
[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "Com.Foo.Request")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "Com.Foo.Request", IsNullable = false)]
public partial class REQUEST_GROUP
{

 [EditorBrowsable(EditorBrowsableState.Never)]
 private List<REQUESTING_PARTY> rEQUESTING_PARTYField;

 [EditorBrowsable(EditorBrowsableState.Never)]
 private RECEIVING_PARTY rECEIVING_PARTYField;

 [EditorBrowsable(EditorBrowsableState.Never)]
 private SUBMITTING_PARTY sUBMITTING_PARTYField;

 [EditorBrowsable(EditorBrowsableState.Never)]
 private REQUEST rEQUESTField;

 [EditorBrowsable(EditorBrowsableState.Never)]
 private string iDField;

 public REQUEST_GROUP()
 {
  this.rEQUESTField = new REQUEST();
  this.sUBMITTING_PARTYField = new SUBMITTING_PARTY();
  this.rECEIVING_PARTYField = new RECEIVING_PARTY();
  this.rEQUESTING_PARTYField = new List<REQUESTING_PARTY>();
  this.IDField = "2.1";
 }
}

使用utf-8编码从Serialize输出:

<?xml version="1.0" encoding="utf-8"?> <REQUEST_GROUP xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" ID="2.1" xmlns="Com.Foo.Request"> <RECEIVING_PARTY /> <SUBMITTING_PARTY /> <REQUEST LoginAccountIdentifier="xxx" LoginAccountPassword="yyy" _RecordIdentifier="" _JobIdentifier=""> <REQUESTDATA> <PROPERTY_INFORMATION_REQUEST _SpecialInstructionsDescription="" _ActionType="Submit"> <_DATA_PRODUCT _ShortSubjectReport="Y" /> <_PROPERTY_CRITERIA _City="Sunshine City" _StreetAddress2="" _StreetAddress="123 Main Street" _State="CA" _PostalCode="12345"> <PARSED_STREET_ADDRESS /> </_PROPERTY_CRITERIA> <_SEARCH_CRITERIA /> <_RESPONSE_CRITERIA /> </PROPERTY_INFORMATION_REQUEST> </REQUESTDATA> </REQUEST> </REQUEST_GROUP>

编辑 问题1:如何以这种方式修饰类,或者在处理期间操纵序列化程序去除REQUEST_GROUP节点中的所有命名空间,而不是使用xslt或regex进行后处理.

问题2:如果您也可以添加文档类型,则可以获得奖励积分.

谢谢.

Answer 1

您可以删除这样的名称空间:

XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add(string.Empty, string.Empty);
ns.Add(string.Empty, "Com.Foo.Request");
Serializer.Serialize(xmlWriter, this, ns);

至于添加doctype,我知道可以创建一个自定义XmlWriter,只是覆盖WriteStartDocument一个调用方法WriteDocType,但我希望别人知道一个比这更简单的方法.

编辑:顺便说一句,我强烈建议使用using:

using(System.Xml.XmlWriter xmlWriter = XmlWriter.Create(etc.))
{
  // use it here.
}

它会Dispose在块结束时通过调用方法自动处理流的整理.
