Scraper will simply ignore the existence of tags that are not mentioned on the template. For example:
If your template is:
And your html is:
Scraper will look at your html as if it was:
<p> Something, something something </p>
your <b> text </b>
As you can see, the tags body, p. /p, b, /b and /body will be completely ignored because they are not mentioned on the template.
But ignoring tag does not mean ignoring text. Anytime a tag is removed, it's content (text) is appended to the previous tag.
Ah, scraper has no notion of nesting or well-formed html. It simply recognizes anything inside < and > as a tag. Why did we do that? Because the web is a really heterogeneous environment. After analyzing more than 20,000 pages, we found lots of crappy coded pages, including mistyped tags, invalid tags, crazy tags on strange namespaces (I'm looking at you, MicroSoft!) and a whole lot more of things that shouldn't exist. The only way we found of consistently parsing that was being able to execute on any kind of awful environment. This also brought a benefit. We can extract information from anything that is marked using < and > . This includes any Html, Xml or your custom format!
