"In this tutorial, you will be given a gentle introduction to `XPath "
"<https://en.wikipedia.org/wiki/XPath>`_, a query language that can be used "
"to select arbitrary parts of `HTML <https://en.wikipedia.org/wiki/HTML>`_ "
"documents in calibre. XPath is a widely used standard, and googling it will "
"yield a ton of information. This tutorial, however, focuses on using XPath "
"for e-book related tasks like finding chapter headings in an unstructured "
"HTML document."
msgstr "Στο βοήθημα αυτό θα βρείτε μια χαλαρή εισαγωγή στο `XPath <https://en.wikipedia.org/wiki/XPath>`_, μια γλώσσα αναζήτησης που μπορεί να χρησιμοποιηθεί για να επιλεγούν οποιαδήποτε τμήματα κώδικα `HTML <https://en.wikipedia.org/wiki/HTML>`_ εγγράφων του calibre. Το XPath είναι ένα ευρέως διαδεδομένο στάνταρ, και αναζήτηση γι' αυτό στον ιστό θα δώσει πλήθος πληροφοριών. Το βοήθημα αυτό όμως, εστιάζει στη χρήση του XPath για εργασίες που σχετίζονται με τα ψηφιακά βιβλία, όπως την εύρεση τίτλων κεφαλαίων σε ένα έγγραφο HTML χωρίς δομή."

"tags. The ``h:`` prefix in the above examples is needed to match XHTML tags."
" This is because internally, calibre represents all content as XHTML. In "
"XHTML tags have a *namespace*, and ``h:`` is the namespace prefix for HTML "
"tags."

"Now suppose you want to select both ``<h1>`` and ``<h2>`` tags. To do that, "
"we need a XPath construct called *predicate*. A :dfn:`predicate` is simply a"
" test that is used to select tags. Tests can be arbitrarily powerful and as "
"this tutorial progresses, you will see more powerful examples. A predicate "
"is created by enclosing the test expression in square brackets::"

"There are several new features in this XPath expression. The first is the "
"use of the wildcard ``*``. It means *match any tag*. Now look at the test "
"expression ``name()='h1' or name()='h2'``. :term:`name()` is an example of a"
" *built-in function*. It simply evaluates to the name of the tag. So by "
"using it, we can select tags whose names are either `h1` or `h2`. Note that "
"the :term:`name()` function ignores namespaces so that there is no need for "
"the ``h:`` prefix. XPath has several useful built-in functions. A few more "
"will be introduced in this tutorial."
