It is also possible to save XML documents existing in memory to disk and to serialize them. It eliminates the need for a developer to learn the XML query language which is somewhat complex.
Generating XML Trees
To jump-start our examples, we will use our Faculty data model from previous articles to combine LINQ to Entities and LINQ to XML features.
Manipulating XML
Now we want to make all female students a year younger and interested in programming if they are not already.
Conclusion
XML is a widely used data format that is applicable in many contexts and technologies. LINQ to XML adds even more flexibility and usability thanks to LINQ integration. You might have noted that the above examples are a little like those we already covered in previous articles related to other LINQ technologies.
