|
---|
| 42 | * <p>
|
---|
| 43 | * This command condenses an HTML GUI model. For HTML GUI models, this is a special task, as, e.g.,
|
---|
| 44 | * menu structures resisting on several pages of a website are identified separately. However, for
|
---|
| 45 | * subsequent analysis, they need to be treated as identical. Therefore, this command identifies
|
---|
| 46 | * pages (i.e. documents) with equal structures and merges them. For differences in the pages, it
|
---|
| 47 | * adds groups of GUI elements indicating, which GUI element belongs to which pages and not to
|
---|
| 48 | * others.
|
---|
| 49 | * </p>
|
---|
| 50 | * <p>
|
---|
| 51 | * An example for clarification. Consider the following two pages:
|
---|
| 52 | * <pre>
|
---|
| 53 | * server
|
---|
| 54 | * |-- document1
|
---|
| 55 | * | \-- html
|
---|
| 56 | * | \-- body
|
---|
| 57 | * | |-- div (id = menu)
|
---|
| 58 | * | | \-- ...
|
---|
| 59 | * | |-- div (id = textcontent)
|
---|
| 60 | * | | \-- ...
|
---|
| 61 | * | \-- div (id = footer)
|
---|
| 62 | * | \-- ...
|
---|
| 63 | * \-- document2
|
---|
| 64 | * \-- html
|
---|
| 65 | * \-- body
|
---|
| 66 | * |-- div (id = menu)
|
---|
| 67 | * | \-- ...
|
---|
| 68 | * |-- div (id = imagecontent)
|
---|
| 69 | * | \-- ...
|
---|
| 70 | * \-- div (id = footer)
|
---|
| 71 | * \-- ...
|
---|
| 72 | * </pre>
|
---|
| 73 | * They only differ in the central div which has the id textcontent for the first document and
|
---|
| 74 | * imagecontent for the second. The above GUI model is the result of the monitoring and parsing of
|
---|
| 75 | * the log files. This command condenses the GUI model to the following structure:
|
---|
| 76 | * <pre>
|
---|
| 77 | * server
|
---|
| 78 | * \-- document1
|
---|
| 79 | * \-- html
|
---|
| 80 | * \-- body
|
---|
[1336] | 81 | * |-- div (id = menu)
|
---|
| 82 | * | \-- ...
|
---|
[1286] | 83 | * |-- group (document1)
|
---|
| 84 | * | \-- div (id = textcontent)
|
---|
| 85 | * | \-- ...
|
---|
| 86 | * |-- group (document2)
|
---|
| 87 | * | \-- div (id = imagecontent)
|
---|
| 88 | * | \-- ...
|
---|
[1336] | 89 | * \-- div (id = footer)
|
---|
| 90 | * \-- ...
|
---|
[1286] | 91 | * </pre>
|
---|
| 92 | * This now allows the menu and the footer to be treated as identical over several pages.
|
---|
| 93 | * </p>
|
---|
| 94 | * <p>
|
---|
| 95 | * If several but not all pages share similarities, the created groups refer to several documents
|
---|
| 96 | * at once.
|
---|
| 97 | * </p>
