NAME

VERSION

version 1.11.3 Yahoo::Search::Result -- class representing a single result (single web page, image, video file, etc) from a Yahoo! search-engine query. (This package is included in, and automatically loaded by, the Yahoo::Search package.)

Package Use

You never need to use this package directly -- it is loaded automatically by Yahoo::Search.

Object Creation

Result objects are created automatically when a Response object is created (when a Request object's Fetch method is called, either directly, or indirectly via a shortcut such as Yahoo::Search->Query().

Those items marked with a '*' are also available via the Data method

METHODS

$Result->Next([boolean])

Returns the next Result object from among the list of result objects that are part of one Response object.

Returns nothing when called on the last result in a response, unless auto-continuation is turned on, in which case the next set is automatically fetched and the first Result from that set's Response is returned.

An optional defined boolean argument turns auto-continuation on (true) or off (false). If the argument is not defined, or not provided, the value for the original request's AutoContinue option (default off) is used.

Note that using auto-continuation can be dangerous. See the docs for NextResult in Yahoo::Search::Response.

$Result->Prev

The opposite of Next. No auto-continuation feature.

$Result->Response

Returns the Response object of which this Result object is a part.

$Result->Request

Returns the original Request object from which this Result object's Response was derived.

$Result->SearchSpace

Returns a string which indicates the search space of the original query that this result was part of. (That is, it returns Doc, Image, News, Local, or Video.)

It's the same as

$Result->Request->SearchSpace;

$Result->i[ separator ]

$Result->I[ separator ]

The first (lower-case letter "i") returns the zero-based ordinal of the result from among those in the current Response.

The latter (upper-case letter "I") returns the zero-based ordinal of the result from among all search results that might be returned by Yahoo! for the given query.

For example, after

my @Results = Yahoo::Search->Results(Image => "Briteny",
                                     AppId => "my app id",
                                     Start => 45,
                                     Count => 15);

the $Results[0] result object has an I of 45 (the 45th result of all "Briteny" image results) and an i of 0 (the 0th result among those returned this time.)

In either case, if an optional argument is given and is true, it is used as a separator every three digits. In the US, one would use

$Result->I(',')

to return "1,234" where

$Result->I()

would return "1234".

$Result->as_html

Returns a string of HTML that represents the result, as appropriate to the result's query search space.

There are many ways one may wish to display query results -- this method returns one display that the author finds useful. It may come in useful for quick prototyping of web applications, e.g.

sub ShowRelated
{
  print join "<hr>", map { $_->as_html } Yahoo::Search->Results(@_);
}

(Also see Yahoo::Search->HtmlResults)

The HTML returned by as_html contains class references, thereby allowing the look-and-feel to be easily adjusted. Here's a style sheet that makes Image search results look palatable.

<style>
  .yResult { display: block; border: #CCF 3px solid ; padding:10px }
  .yLink   { }
  .yTitle  { display:none }
  .yImg    { border: solid 1px }
  .yUrl    { display:none }
  .yMeta   { font-size: 80% }
  .ySrcUrl { }
  .ySum    { font-family: arial; font-size: 90% }
</style>

Bugs: English-centric

$Result->as_string

Returns a textual representation of the Result, which may be useful for quick prototyping or debugging.

$Result->Data

Returns a list of key/value pairs containing the fundamental data for the result (those items marked with '*' in the table at the start of this document).

my %Data = $Result->Data;

$Result->Url

$Result->ClickUrl

Url returns the raw url of the item (web page, image, etc.), appropriate for display to the user.

ClickUrl returns a url appropriate for the href attribute of a link.

In some cases, the two return the same url.

As with all Result-object methods which return a url of some sort, you can provide a single argument such as href and receive a string such as href="..." appropriate to be used directly in html. For example,

my $HREF = $Result->ClickUrl('href');
print "<a $HREF>click</a>";

is preferable to

my $url = $Result->ClickUrl;
print "<a href='$url'>click</a>";

since the latter would break if $url contains a singlequote.

$Result->Title([ as_html ])

$Result->TitleAsHtml

Title returns the raw title text associated with the result. If an optional argument is provided and is true, the title text is returned as html.

TitleAsHtml is the same as

$Result->Title(1)

$Result->Link

Returns a link made from the ClickUrl and the Title, with class "yLink", e.g.

<a class=yLink href='$URL'>$TITLE</a>

$Result->Summary([ as_html ])

$Result->SummaryAsHtml

Like Title and TitleAsHtml, but for the summary associated with the result.

$Result->CacheUrl

$Result->CacheSize

(Appropriate for Doc search results)

CacheUrl returns the url of the document in the Yahoo! cache. See the documentation for the Url method for information on the one-argument version of this method.

CacheSize returns the size (as a string like "22k").

$Result->ModTimestamp

(Appropriate for Doc and News search results)

The Unix timestamp of the Last-Modified time associated with the the url when it was last checked by Yahoo!'s backend crawlers.

$Result->Width

$Result->Height

(Appropriate for Image and Video search results)

The width and height (in pixels) of the image or video.

$Result->ThumbUrl

$Result->ThumbWidth

$Result->ThumbHeight

(Appropriate for Image, Video, and News search results)

The url of a thumbnail image, and its width and height.

(Note: few News results have a thumbnail, but some do.)

See the documentation for the Url method for information on the one-argument version of ThumbUrl.

$Result->ThumbImg

(Appropriate for Image, Video, and News search results)

Returns a <img> tag representing the thumbnail image, e.g.

<img class=yImg src='$IMGURL' width=$WIDTH height=$HEIGHT>

$Result->ThumbLink

(Appropriate for Image, Video, and News search results)

Returns a link from the thumbnail to the ClickUrl of the result, e.g.

<a class=yLink href='$CLICKURL'>
  <img class=yImg src='$IMGURL' width=$WIDTH height=$HEIGHT>
</a>

$Result->HostUrl

(Appropriate for Image and Video search results)

Returns the url of the web page containing a link to the image/video item that the Result represents.

See the documentation for the Url method for information on the one-argument version of this method.

$Result->Type

(<Appropriate for Doc, Image, and Video search results>)

Returns a string representing the file type of the item to which $Result->Url points. For Doc searches, the MIME type (e.g. "text/html") is returned.

For other search spaces, here are the possible return values:

Video:  avi  flash  mpeg  msmedia  quicktime  realmedia
Image:  bmp  gif  jpg  png.

Yahoo! Search derives these Video/Image Type value by actually inspecting the file contents, and as such it is more reliable than looking at the file extension.

$Result->Copyright([ as_html ])

(<Appropriate for Image and Video search results>)

Returns any copyright notice associated with the result. If an optional argument is provided and is true, the copyright text is returned as html.

$Result->Publisher([ as_html ])

(<Appropriate for Image, and Video search results>)

Returns any publisher information (as a string) associated with the result. If an optional argument is provided and is true, the publisher information is returned as html.

$Result->Restrictions

(<Appropriate for Image, and Video search results>)

A (possibly zero-length) string containing zero or more of the following space-separated words:

noframe
noinline

See Yahoo!'s web site (http://developer.yahoo.net/) for information on them.

$Result->Bytes

(Appropriate for Image, and Video search results)

The size of the image/video item, in bytes.

$Result->Channels

(Appropriate for Video search results)

Returns the number of channels in the audio, if known. Examples are "1", "2", "4.1", "5.1", etc....

$Result->Seconds

(Appropriate for Video search results)

Returns the duration of the video clip, if known, in (possibly fractional) seconds.

$Result->Duration

(Appropriate for Video search results)

Returns a string representing the duration of the video clip, if known, in the form of "37 sec", "1:23", or "4:56:23", as appropriate.

Bugs: English-centric

$Result->Streaming

(Appropriate for Video search results)

Returns "1" if the multimedia is streaming, "0" if not. If not known, an empty list is returned.

$Result->SourceUrl

(Appropriate for News search results)

The main url of the news provider hosting the article that the Result refers to.

See the documentation for the Url method for information on the one-argument version of this method.

$Result->SourceName([ as_html ])

$Result->SourceNameAsHtml

(Appropriate for News search results)

Similar to Title and TitleAsHtml, but the name of the organization associated with the news article (and, by extension, with SourceUrl).

$Result->Language

(Appropriate for News search results)

A code representing the language in which the article is written (e.g. "en" for English, "ja" for Japanese, etc.). See the list of language codes at perldoc Yahoo::Search.

$Result->PublishTime

$Result->PublishWhen

(Appropriate for News search results)

PublishTime is the Unix time associated with the article, e.g.

print "Published ", scalar(localtime $Result->PublishTime), "\n";

PublishWhen gives a string along the lines of

3h 25m ago              (if less than 12 hours ago)
Tue 9:47am              (if less than 5 days ago)
Sat, Dec 25             (if less than 100 days ago)
Sat, Dec 25, 2004       (if >= 100 days ago)

Bug: PublishWhen is English-centric.
