Smart Content Analysis check method lets you monitor any part(s) of an HTML document or presence\absence of specified keyword(s). So you can create your own analysis conditions to analyse resource most precisely. Right Web Monitor lets you create any number of conditions for each monitoring resource. All the conditions you will create will be placed one-by-one and in case if at least one condition is satisfied¹ the resource presumes Modified².

The conditions can be of the following types:

"Analyse entire page" condition can be used for analysing full content of page from the very beginning to the end.
"Analyse specified fragment" condition can be used for analysing specified fragment of page. To determine its bounds you should specify the initial and ending fragments.
"Look up for specified keywords" condition can be used if you want the program to analyse specified keywords presence or absence.

1. Analysing entire page

Once resource is downloaded the program applies the source processing flags and compares the resulting data for previously saved version and currently downloaded version. In case if it finds any difference the condition presumes satisfied.

2. Analysing specified fragment

Screenshot #1

Once resource is downloaded the program selects specified fragment, applies the source processing flags and compares the resulting data for previously saved version and last saved version. In case if it finds any difference the condition presumes satisfied.

If you want Internet Explorer core to extract fragments from HTML just mark "Use IE core to extract fragments". This option must be enabled when Page Content Recorder has been used to define initial and ending fragments. If this option is enabled the extracting of the fragments will become slower.

Example #1:

If you need to check the latest news on the RightSoft site you should create a new link with http://www.right-soft.com/news/ URL, go to its properties, select "Analysis" page, then select "Smart Content Analysis", select the default condition (it will be created automatically) and press the "Edit" button. The following dialog will appear (screenshot #1):

Press "View source" button to browse the source of the document. Find the following text:



...
<b><a href="../webmon/">Right Web Monitor</a></b> 1.5 is now available.<br>

...


or any other text placed between the "" and the "" fragments. This is the latest news text. Select the initial and ending fragments and fill in the corresponding fields as shown on the screenshot #1. Press "OK" buttons on this dialog and on "Link Properties" dialog. Now, when the program detects that text between the initial and ending fragments changed the condition presumes satisfied.

3. Looking up for specified keywords

Keywords analysing can be of two types:

Analysing for presence - keyword have to start with the +(plus) sign, for example +"keyword1". If the program detects that such keyword is present in the page it presumes that this keyword satisfies the condition.

Analysing for absence - keyword have to start with the -(minus) sign, for example -"keyword2". If the program detects that such keyword is absent in the page it presumes that this keyword satisfies the condition.

Once resource is downloaded the program applies the source processing flags and searches for specified keywords within the resulting data for currently downloaded version. In case if at least one keyword satisfies the condition, the condition presumes satisfied.

Screenshot #2

If you want the program to notify you only if all the keywords satisfy the condition just mark on the corresponding checkbox.

If you want the program to look up for keywords only within specified region just mark the corresponding checkbox and enter variable(s) that represents a region where keywords should be looked up.

Keywords analysing of the both types can be used in the same condition simultaneously. Keywords must have the following syntax: +"keyword1" -"keyword2" -"a keyphrase with space" i.e. keywords can contain spaces, but have to start with + or - (plus or minus) signs, be placed in quotation marks (") and separated with spaces. Keywords must not contain quotation marks themselves.

Example #2:

If you want the program to notify you only when Right Web Monitor related news are published just follow the steps below:

Create a condition as described in Example #1 .

Create a new condition and set its type to "Look up for specified keywords".

Enter +"Right Web Monitor" into the "Keywords" edit field.

Enable "Look for keywords only within" check box and enter %SELECTEDFRAGMENTS% into the edit field below. Content Analysis options windows should look like the one on the screenshot #2. Press the "OK" button.

Mark on the "Mark as Modified only when all the conditions are satisfied" checkbox.

The program will act this way:

Step #1: if the program detects that text between the "" and the "" fragments (hereinafter TEXT) has been changed the first condition presumes satisfied and the program proceeds to the Step #2.

Step #2: if the program finds "Right Web Monitor" phrase in the TEXT the second condition presumes satisfied. So that we have only two conditions and both of them are satisfied the program presumes resource Modified².

Source processing flags

Right Web Monitor applies source processing flags once resource is downloaded and before analysing it. Source processing flags can be of the following types:

Page source / Visible text only - if Page source flag is selected, the program analyses HTML source and visible text. If Visible text only flag is selected the program removes all the HTML tags and scripts before analysing.

Ignoring tags - if this flag is selected the program removes the specified HTML tags from the analysed data. This flag makes sense only if Page source flag is selected.

Trim multiple spaces and line breaks - if this flag is selected the program removes all the multiple spaces between words (leaves only one space between two words) and CF/LF (Caret Return / Line Feed) sequences.

Default condition

Once you've selected Smart Content Analysis as analysis method for a resource, the program automatically creates a condition with "Entire page, analysing visible text only" description. This condition is of "Analysing entire page" type with "Visible text only" flag selected. So the program will analyse visible text of the whole page, i.e. if any differences between visual parts of previously saved copy and currently downloaded copy are detected the resource presumes Modified². It works similar to Exact Content Analysis but ignores all the HTML tags, so it is convenient to use it instead of Exact Content Analysis if monitoring resource is a page with dynamical links, visitor counters, date/time stamps and so on.

¹- However if "Link Properties > Analysis > Smart Content Analysis options > Mark as Modified only when all the conditions are satisfied" option is enabled all the condition have to be satisfied to mark link as Modified and fire notification alerts.
² - The fact that resource presumes Modified means that status of the link is changed, link representation in Links View becomes in bold typeface and notification alerts fire.

Examples:

Example - Smart Content Analysis: analysing certain fragment of a web page,

Example - Smart Content Analysis: monitoring keywords within certain region .
