Run

Sample xml file is included with the solution. Just run the following command:

./xmlreport products.xml --print-all

output:

            products
                product
                    name
                    description

Uses of this software

• Check if the xml is valid.
• Get values of elements.

Send me a PR for

• Querying and printing attributes. This software already parses attributes(see XmlAttribute and use --print-all option) but is not concerned with printing them.
• Security, typesafety enhancements

Program Specifications

C++ program called "xmlreport" that runs from the command line. Parses any valid XML file and prints a report following the rules below. The program will return 0 when successful, or 1 for any error detected.

The syntax is as follows:

./xmlreport filename [--version] [--element:] [--element:] [...]

1. When using xmlreport with the file products.xml only, the output will produce all unique elements. All elements starting with <? can be ignored for this output.

example:

./xmlreport products.xml --print-all

output:

            products
                product
                    name
                    description
                    country
                    company
                    cost
                    type

2. When using xmlreport with the file products.xml and --version, a report will output all unique elements and version number. Note that --version should always be provided as the second param...

example:

./xmlreport products.xml --version --print-all

output:

    products
        product
            name
            description
            country
            company
            cost
            type

    version = 1.0

3. When using xmlreport with the file products.xml and --element:, a report will output the all unique data for the listed elements at the same level, in the order of the listed elements.

E.g. if the level is then all elements matching that level will be output.

example:

./xmlreport products.xml --element:name

output:

    Apple
    Pear
    Grapes
    shirt
    ...

example:

./xmlreport products.xml --element:name --element:cost

output:

    Apple, £0.17
    Pear, £0.12
    Grapes, £0.78
    shirt, £7.45
    ...

example:

./xmlreport products.xml --element:cost --element:name

output:

    £0.17, Apple
    £0.12, Pear
    £0.78, Grapes
    £7.45, shirt
    ...
