# xml-processing

Examples for XML processing in different programming languages.

The exercises below are simple instances of common real-world XML processing

tasks: selection of elements, modification of element content, modification of

the XML tree and validation against an XML schema. The [example XML

file](xml/example.xml) and the [underlying schema](xml/gtr_dc.xsd) can be found

in the xml directory.

improvements of the existing solutions!

# Exercises

## Exercise 1

Print a list of all leaf node creators and titles, i.e., all `content/creator`

and `content/title` children of `node` elements that contain no other `node`

elements as children. Each item should be a line of the form "creator, title".

## Exercise 2

Same as exercise 1, but consider the case where some leaf nodes have no creator

element. Search their ancestors until a creator element is found and print that

instead.

## Exercise 3

Make the content of all `title` elements uppercase. Print the resulting XML

document.

## Exercise 4

Add a new item to the end of the "A Song of Ice and Fire" section with title "A

Feast for Crows" and date "2005". Print the resulting XML document.

## Exercise 5

Remove the "Programming Books" section. Print the resulting XML document.

## Exercise 6

Validate the XML document. Keep in mind that the schema file references

additional external schema files that have to be retrieved from the internet, so

internet access is required for validation.

## Exercise 7

Flatten the XML hierarchy by removing the top level nodes (those immediately

below the `tree` root element). Add a `content/subject` element to all their

immediate child nodes that preserves the `name` attribute value of the removed

parent node ("Programming Books" or "Fantasy Books", respectively). Print the

resulting XML document.

## Exercise 8

Reverse exercise 7: Create a new top level node for each distinct subject found

in the current top level nodes. Move each node to its respective parent node

(one of the new top level nodes). Remove the subject elements. Print the

resulting XML document.
