/*
*
* The DroidDoc format from API Level 16 to 23, the format is:
*
* - All pages have ToC links and body (unlike standard JavaDoc which is based on HTML frames).
* - The actual doc section is a div element whose id is "doc-col".
* - The "doc-col" div element has a section div element whose id is "jd-header" and another one with id "jd-content".
* - "jd-header" div element contains the type signature (modifiers, name, and inheritance).
* - Here we care only about type name and kind (whether it is a class or interface).
* - Generic arguments are insignificant.
* - In the following terms I explain the "correct" (or "expected") document structure, but in fact
* Google completely broke it and it is impossible to retrieve the document tree like this.
* We workaround this issue by changing the strategy "iterate children of 'jd-content'"
* with "iterate descendants of 'jd-content'"... It occurs only in API Level 15 or later.
* - "jd-content" div element contains a collection of sections. Each section consists of:
* - an "h2" element whose value text indicates the section name ("Public Constructors", "Protected Methods" etc.)
* - There was an issue in javax/xml/validation/SchemaFactory.html in API Level 15 that the method details contain
* "h2" and confuses the parser. To workaround this, we accept only limited kind of values.
* - the content, which follows the h2 element.
* - The section content is a collection of members. Each member consists of:
* - an anchor ("A") element with "name" attribute, and
* - a div element which contains an h4 child element whose class contains "jd-details-title".
* - The h4 element contains the member signature. We parse it and retrieve the method name and list of parameters.
* - Parameters are tokenized by ", ".
* - Note that the splitter contains a white space which disambiguates any use of generic arguments (we don't want to split "Foo<K,V> bar" as "Foo<K" and "V> bar")
*
* API Level 10 to 15 has slightly different format:
*
* - There is no "doc-col" element. But "jd-header" and "jd-content" are still alive.
