rssInitialize (Function) In french: rssInitialise Loads a RSS feed in memory.
MyRSSStream is rssStream
MyRSSStream = rssInitialize("http://blogs.webdev.info/rss.awp?blog=technicalsupport", fromURL)
Syntax
<Result> = rssInitialize(<Source of RSS Stream> [, <Source type>])
<Result>: rssStream variable rssStream variable containing the characteristics of the specified RSS feed. If the initialization of the stream fails, the stream is empty and ErrorInfo returns more details about the error. <Source of RSS Stream>: Character string Source of the RSS feed used for the initialization. This parameter can correspond to:- An Ansi character string or a buffer containing the content of the RSS feed. In this case, <Source type> must correspond to the fromString constant.
- A character string containing the full path of an XML file. This file must be accessible from the current computer. In this case, <Source type> must correspond to the fromFile constant.
- A character string containing the URL address. The content of the RSS feed is retrieved from this URL. In this case, <Source type> must correspond to the fromURL constant.
<Source type>: Optional Integer constant Indicates the source of the RSS feed to load. | | | fromFile | The RSS feed to load is contained in a file. | | fromString | The RSS feed to load is contained in an Ansi character string or in a buffer. | | fromURL | The RSS feed to load is accessible by a URL. |
An automatic detection is performed if this parameter is not specified. The type of the source is automatically deduced from <Source of RSS Stream>: - if <Source of RSS Stream> starts with "http://", the fromURL constant will be automatically used.
- if <Source of RSS Stream> starts with a drive letter or with a UNC path, the fromFile constant will be automatically used.
- otherwise, the fromString constant will be automatically used.
Remarks Only the streams in RSS 2.0 format are currently supported.
