从C＃LINQ解析XML时，如何保留空白字符

Question

What do I need to do in either my C# code or my XML document so that the XDocument parser reads literal whitespace for Value s of XElement s?

---

Background

I have an XML document, part of which looks like this:

  <NewLineString>&#10;&#13;</NewLineString> <IndentString> </IndentString> 

I'm adding the values of each XELement to a data dictionary using a LINQ query; the .ForEach part looks like this:

  .ForEach(x => SchemaDictionary.Add( LogicHelper.GetEnumValue(x.Name.ToString()), x.Value)); 

To test to see if the whitespace values were preserved, I'm printing out a line of the character numbers of each value item in the data dictionary. In the following code, x represents a KeyValuePair and the Aggregate is simply making a string of the character integer values:

 x.Value.ToCharArray() .Aggregate<char,string>("",(word,c) => word + ((int)c).ToString() + " " ) )); 

I expected to see 10 13 for the <NewLineString> value and 32 32 32 32 for the <IndentString> value. However, nothing was printed for each value ( note: other escaped values in the XML such as < printed their character numbers correctly ).

What do I need to do in either my C# code or my XML document so that my parser adds the complete whitespace string to the Data Dictionary?

Answer 1

尝试使用LoadOptions.PreserveWhitespace加载XDocument

Answer 2

Try loading your document this way.

XmlDocument doc = new XmlDocument();
    doc.PreserveWhitespace = true;
    doc.Load("book.xml");

Answer 3

or just modify your input xml to:

<NewLineString>&#10;&#13;</NewLineString>
<IndentString xml:space="preserve">    </IndentString>
