protected RSS090Parser(java.lang.String type)

Method Detail

isMyType

public boolean isMyType(org.jdom.Document document)

Description copied from interface: com.sun.syndication.io.WireFeedParser

Inspects an XML Document (JDOM) to check if it can parse it.

It checks if the given document if the type of feeds the parser understands.

---

parse

public com.sun.syndication.feed.WireFeed parse(org.jdom.Document document,
                                               boolean validate)
                                        throws java.lang.IllegalArgumentException,
                                               com.sun.syndication.io.FeedException

Description copied from interface: com.sun.syndication.io.WireFeedParser

Parses an XML document (JDOM Document) into a feed bean.

---

validateFeed

protected void validateFeed(org.jdom.Document document)
                     throws com.sun.syndication.io.FeedException

---

getRSSNamespace

protected org.jdom.Namespace getRSSNamespace()

Returns the namespace used by RSS elements in document of the RSS version the parser supports.

This implementation returns the EMTPY namespace.

---

getRDFNamespace

protected org.jdom.Namespace getRDFNamespace()

Returns the namespace used by RDF elements in document of the RSS version the parser supports.

This implementation returns the EMTPY namespace.

---

parseChannel

protected com.sun.syndication.feed.WireFeed parseChannel(org.jdom.Element rssRoot)

Parses the root element of an RSS document into a Channel bean.

It reads title, link and description and delegates to parseImage, parseItems and parseTextInput. This delegation always passes the root element of the RSS document as different RSS version may have this information in different parts of the XML tree (no assumptions made thanks to the specs variaty)

---

getItems

protected java.util.List getItems(org.jdom.Element rssRoot)

This method exists because RSS0.90 and RSS1.0 have the 'item' elements under the root elemment. And RSS0.91, RSS0.02, RSS0.93, RSS0.94 and RSS2.0 have the item elements under the 'channel' element.

---

getImage

protected org.jdom.Element getImage(org.jdom.Element rssRoot)

This method exists because RSS0.90 and RSS1.0 have the 'image' element under the root elemment. And RSS0.91, RSS0.02, RSS0.93, RSS0.94 and RSS2.0 have it under the 'channel' element.

---

getTextInput

protected org.jdom.Element getTextInput(org.jdom.Element rssRoot)

This method exists because RSS0.90 and RSS1.0 have the 'textinput' element under the root elemment. And RSS0.91, RSS0.02, RSS0.93, RSS0.94 and RSS2.0 have it under the 'channel' element.

---

parseImage

protected com.sun.syndication.feed.rss.Image parseImage(org.jdom.Element rssRoot)

Parses the root element of an RSS document looking for image information.

It reads title and url out of the 'image' element.

---

parseItems

protected java.util.List parseItems(org.jdom.Element rssRoot)

Parses the root element of an RSS document looking for all items information.

It iterates through the item elements list, obtained from the getItems() method, and invoke parseItem() for each item element. The resulting RSSItem of each item element is stored in a list.

---

parseItem

protected com.sun.syndication.feed.rss.Item parseItem(org.jdom.Element rssRoot,
                                                      org.jdom.Element eItem)

Parses an item element of an RSS document looking for item information.

It reads title and link out of the 'item' element.

---

parseTextInput

protected com.sun.syndication.feed.rss.TextInput parseTextInput(org.jdom.Element rssRoot)

Parses the root element of an RSS document looking for text-input information.

It reads title, description, name and link out of the 'textinput' or 'textInput' element.
