Accompanies PR #56 . This section includes multiple FIXME headings that lead me to assume it wasn't meant to be in the public version of the lesson.
Maintainers should determine whether to add corrected/complete information on some/all of these topics or remove them entirely. Merging the PR would remove it from the published lesson. At that point this issue can be used to discuss longer-term solutions.
Additions
FIXME: add more XPath functions such as concat() and normalize-space().
FIXME: mention XPath Checker for Firefox
FIXME: Firefox sometime cleans up the HTML of a page before displaying it, meaning that the DOM tree
we can access through the console might not reflect the actual source code. <tbody> elements are
typically not reliable.
The Scrapy documentation
has more on the topic.
