New article HTML Walkthrough Using MQL4 has been published:

HTML is nowadays one of the wide-spread types of documents. MetaTrader 4 Client Terminal allows you to save statements, test and optimization reports as .htm files. It is sometimes necessary to get information from such files in an MQL4 program. The article describes one of variations of how to get the tag structure and contents from HTML.

In terms of a simple description, tag is any word enclosed in angle brackets. For example, this is a tag: <tag>, although, in HTML, tags are certain words typed in Latin letters. For example, <html> is a correct tag, but there is no tag <html2>. Besides, many tags can have additional attributes that precise formatting performed by the given tag. For example, <div align="center"> means tag <div> in which the additional attribute of center alignment of the tag content is specified.

Tags are usually utilized in pairs: there are opening and closing tags. They differ from each other only with the presence of slash. Tag <div> is an opening tag, while tag </div> is a closing one. All data enclosed between the opening and the closing tags is named tag content. It is this content we are interested in at HTML code walkthrough.
