In OllieFord/ChangepointVis: Interactive Visualization for Change Point Exploration and Labeling

rvest 0.3.4

• Remove unneeded read_xml.response() method (#242).

rvest 0.3.3

• Fix R CMD check failure

• submit_request() now checks for empty form-field-types to select the correct submit fields (@rentrop, #159)

rvest 0.3.2

• Fixes to follow_link() and back() to correctly manage session history.

• If you're using xml2 1.0.0, html_node() will now return a "missing node".

• Parse rowspans and colspans effectively by filling using repetition from left to right (for colspan) and top to bottom (rowspan) (#111)

• Updated a few examples and demos where the website structure has changed.

• Made compatible with both xml2 0.1.2 and 1.0.0.

rvest 0.3.1

• Fix invalid link for SSA example.

• Parse <options> that don't have value attribute (#85).

• Remove all remaining uses of html() in favor of read_html() (@jimhester, #113).

rvest 0.3.0

• rvest has been rewritten to take advantage of the new xml2 package. xml2 provides a fresh binding to libxml2, avoiding many of the work-arounds previously needed for the XML package. Now rvest depends on the xml2 package, so all the xml functions are available, and rvest adds a thin wrapper for html.

• A number of functions have change names. The old versions still work, but are deprecated and will be removed in rvest 0.4.0.

• html_tag() -> html_name()

• html() -> read_html()

• html_node() now throws an error if there are no matches, and a warning if there's more than one match. I think this should make it more likely to fail clearly when the structure of the page changes.

• xml_structure() has been moved to xml2. New html_structure() (also in xml2) highlights id and class attributes (#78).

• submit_form() now works with forms that use GET (#66).

• submit_request() (and hence submit_form()) is now case-insensitive, and so will find <input type=SUBMIT> as well as<input type="submit">.

• submit_request() (and hence submit_form()) recognizes forms with <input type="image"> as a valid form submission button.

rvest 0.2.0

New features

• html() and xml() pass ... on to httr::GET() so you can more finely control the request (#48).

• Add xml support: parse with xml(), then work with using xml_node(), xml_attr(), xml_attrs(), xml_text() and xml_tag() (#24).

• xml_structure(): new function that displays the structure (i.e. tag and attribute names) of a xml/html object (#10).

Bug fixes

• follow_link() now accepts css and xpath selectors. (#38, #41, #42)

• html() does a better job of dealing with encodings (passing the problem on to XML::parseHTML()) instead of trying to do it itself (#25, #50).

• html_attr() returns default value when input is NULL (#49)

• Add missing html_node() method for session.

• html_nodes() now returns an empty list if no elements are found (#31).

• submit_form() converts relative paths to absolute URLs (#52). It also deals better with 0-length inputs (#29).
