    Writing XML

    Liquid XML Objects generates an XML Data Model from an XML Schema with functionality to serialize XML documents out of the XML Data Model. Consider the following XML Schema:

     Sample XML Schema

     Sample Writer Code

    The following code illustrates how to create a new instance of bookstore from scratch and populate it.

    In order to serialize the class to XML an LxSerializer object is required.

    Writing data into the generated classes
    Copy Code 
    BookstoreElm bookstore = new BookstoreElm();
BookTypeCt book = new BookTypeCt();
book.Title = "Artemis";
book.Author.First_Name = "Andy";
book.Author.Last_Name = "Weir";
book.Genre = BookTypeCt.GenreEnum.Science_Fiction;
book.Price = 7.99;
book.ISBN = "978-1-78-503025-3";
book.Publicationdate = LxDateTime.CreateDate(2017, 4, 23);

bookstore.Books.Add(book);

LxSerializer<BookstoreElm> serializer = new LxSerializer<BookstoreElm>();
using (StringWriter sw = new StringWriter())
{
    serializer.Serialize(sw, bookstore);

    Console.WriteLine(sw.ToString());
}

     

    This example code is generated using the default 'Simplified Model', other model options are explored in Code Generation Models.
     XML Output
    BookstoreSample.xml
    Copy Code 
    <?xml version="1.0" encoding="utf-16"?>
<bookstore xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.liquid-technologies.com/sample/bookstore">
  <book price="7.99" publicationdate="2017-04-23Z" ISBN="978-1-78-503025-3">
    <title>Artemis</title>
    <author>
      <first-name>Andy</first-name>
      <last-name>Weir</last-name>
    </author>
    <genre>Science fiction</genre>
  </book>
</bookstore>

     

     

    LxSerializer

    The LxSerializer uses the meta data attributes associated with the generated class to serialize and de-serialize them to XML.

    The easiest way to use the LxSerializer class is via the generic wrapper LxSerializer<T>. The templated version does some of the configuration and casting making it easier to work with.

    The LxSerializer object is quite expensive to create, and LxSerializer<T> will implicitly create an LxSerializer instance in its constructor (unless one is explicitly supplied). So if your code repeatedly creates instances of LxSerializer<T> (for the same or different types of T), then you should consider explicitly creating an instance of  LxSerializer and passing it to the constructor of LxSerializer<T>.

    LxSerializer (and thus LxSerializer<T>) are not thread safe. i.e. don't share them between threads.
