Hi Julia,
Does BaseX create an index of these files so that I could for example query for example
for persons with the same name?
BaseX will create a database from these files. This can e.g. be done by starting the GUI, choosing "Database" → "New…", selecting your XML directory, and pressing OK.
All documents will then be stored, and the textual contents will be indexed. Next, you can use XQuery, which is not only a query language, but a powerful programming language, to do all kinds of things with the data. See e.g. [1] or [2] for some examples. You probably don't want to do that by yourself, but XQuery can be used to write full web applications.
If I want to change something in these files, will the changes be also made in the xml documents?
Currently, there is no automatic synchronisation between databases and local file directories, so you'll either have to export the database after updates, or create a new database after files have been changed.
Cheers, Christian
