Encoding Space Character in Xml Name

Encoding space character in XML name

The XML isn't broken, but it's representing names using a private convention for escaping disallowed characters. The XML parser won't understand this convention, it's up to the receiving application to interpret it.

How to put space character into a string name in XML?

to use white space in xml as string use  . XML won't take white space as it is. it will trim the white space before setting it. So use   instead of single white space

Allowed symbols in XML element name

Right: Letter, digit, hyphen, underscore and period.

One may use any Unicode letter.

And of course one may prefix the names with name space + colon.

Parsing XML with spaces in element names

Unfortunately, the text returned by your library is not a well-formed XML, so you cannot use an XML parser to parse it. The spaces in the tags are only part of the problem; there are other issues, for example, the absence of the "root" tag.

Fortunately, a single-level language is trivial enough to be matched with regular expressions. Regex-based "parsers" would be an awful choice for real XML, but this language is not real, so you could use regex at least as a workaround:

Regex rx = new Regex("<([^>\n]*)>(.*?)</(\\1)>");
var m = rx.Match(text);
while (m.Success) {
    Console.WriteLine("{0}='{1}'", m.Groups[1], m.Groups[2]);
    m = m.NextMatch();
}

The idea behind this approach is to find strings with "opening tags" that match "closing tags" with a slash.

Here is a demo, it produces the following output for your input:

live key='test'
not live='test'
Test='hello'

How do I add a space in an XML schema element?

You can't. That would go against the XML specification. The space character is used as a delimiter in XML and has special meaning. It cannot appear in element names.

Think about the resulting element that you would be defining with that declaration:

<Last Name attribute1="value" attribute2="value">Contents</Last Name>

That doesn't look anything like XML and would be rejected by any XML parser.
