The revision tracking feature in applications—such as Microsoft Word's Track Changes—marks changes to a document (typically, strikethrough for deleted text and underline for inserted text) and tracks each change by reviewer name and date.
If revision tracking was enabled when changes were made to a document, You can configure Export to convert the deleted text and graphics and include revision information in the HTML output. (The deleted content and revision information is excluded from the HTML output by default.)
Content that was added to the document is identified by <ins> tags and is underlined when displayed in a browser. Content that was deleted from the document is identified by <del> tags and is displayed with strikethrough formatting.
The <ins> and <del> tags include the following attributes:

This is an optional attribute that is not included by default. You can define a unique HTML style (such as |

For example, the following markup can be generated for inserted text:
<ins style="color: red" title="Inserted: JohnD, 2006-04-24Tl4:47:00" cite="mailto:JohnD" datetime="2006-04-24T14:47:00">This text was added</ins> in a previous version.
This text is displayed in the browser as:
This text was added in a previous version.
When you hover the cursor over the underlined text in the browser, the text "Inserted: JohnD, 2006-04-24Tl4:47:00" is displayed as a ToolTip.
NOTE: Whether the text is displayed with strikethrough or underline depends on the configuration and capabilities of the browser.
To convert deleted text and graphics and include revision information
Call the fpInit() or fpInitWithLicenseData() function. See fpInit() or fpInitWithLicenseData().
Define the KVRevisionMark structure. See KVRevisionMark.
Call the fpHTMLConfig() function with the following arguments (see KVHTMLConfig()):

For example:
KVRevisionMark RMark; memset(&RMark, 0, sizeof(KVRevisionMark)); KVStructInit(&RMark); RMark... (*fpHTMLConfig)(pKVHTML, KVCFG_INCLREVISIONMARK, TRUE, &RMark))
The htmlini sample program demonstrates this function. See htmlini.
Call the fpConvertStream() or KVHTMLConvertFile() function. See fpConvertStream() or KVHTMLConvertFile().
The title attribute can contain a prefix and revision information which is displayed in a browser. By default, the prefix is either the text string "inserted:" or "deleted:" and the reviewer name and date/time are included in the title.
To exclude the title attribute from the <ins> and <del> tags, set the RM_TITLE_FLAG in the KV_RM_Title structure to RMT_Off. See KV_RM_Title.
To define a different text string for the prefix, specify a new text string in the pPrefix member and set the nSize and eCharSet members of the KV_RM_Title structure. See KV_RM_Title.
To change the revision information included in the title attribute, set the RM_TITLE_FLAG in the KV_RM_Title structure. See RM_Title_Flag.
The following example sets the prefix as "Added:" and "Removed:" for inserted and deleted text respectively, and only includes the reviewer name in the title attribute:
KVRevisionMark RMark; char RMInsPre[16] = "Added:"; char RMDelPre[16] = "Removed:"; memset(&RMark, 0, sizeof(KVRevisionMark)); KVStructInit(&RMark); RMark.InsTitle.eFlag = RMT_Author; RMark.InsTitle.pPrefix = (BYTE *)(&RMInsPre); RMark.InsTitle.nSize = strlen(RMInsPre); RMark.InsTitle.eCharSet = KVCS_UTF8; RMark.DelTitle.eFlag = RMT_Author; RMark.DelTitle.pPrefix = (BYTE *)(&RMDelPre); RMark.DelTitle.nSize = strlen(RMDelPre); RMark.DelTitle.eCharSet = KVCS_UTF8; (*fpHTMLConfig)(pKVHTML, KVCFG_INCLREVISIONMARK, TRUE, &RMark))
You can define a unique HTML style (such as color: red; background: orange) that is applied to each reviewer's modifications. This allows you to easily differentiate between multiple reviewers' edits. For example, changes made by JSmith are highlighted in red, changes made by RBrown are highlighted in blue, and so on.
To define revision styles, set the number of revision styles in the nAuthorStyles member of the KVRevisionMark structure, and use the ppAuthorStyles member for each style to define the contents of the style attribute. See KVRevisionMark.
The following example defines two revision styles:
KVRevisionMark RMark; char RMAuthorStyle0[60] = "color: red; background: yellow"; char RMAuthorStyle1[60] = "color: green; background: silver"; memset(&RMark, 0, sizeof(KVRevisionMark)); KVStructInit(&RMark); RMark.nAuthorStyles = 2; RMark.ppAuthorStyles = (char **)malloc(sizeof(char *)*2); if(!RMark.ppAuthorStyles) return(1); RMark.ppAuthorStyles[0] = RMAuthorStyle0; RMark.ppAuthorStyles[1] = RMAuthorStyle1; (*fpHTMLConfig)(pKVHTML, KVCFG_INCLREVISIONMARK, TRUE, &RMark))
If there are more reviewers than defined styles, KeyView applies all available styles to the reviewers in the order in which they are encountered in the document, and then applies styles starting from the beginning of the list to the remaining reviewers. This process is repeated until all reviewers' edits are highlighted.
NOTE: KeyView does not validate styles. They are written directly to the HTML output.
You can configure Export to summarize the changes made to a document in a revision summary file that is generated during the HTML conversion. The summary file is created in the directory where the HTML output is generated. The default file name is output_filename.revsum.htm . You can customize this file name by using the fpGetAnchor callback function. See GetAnchor().
To create a revision summary file, set the bCreateSummary flag to TRUE in the KVRevisionMark structure, and use the pszRevSumStartBlock and pszRevSumEndBlock members to define the markup and tokens inserted at the beginning and end of the revision summary file.
For example:
KVRevisionMark RMark; char RMStartBlock[500] = "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN"> <html> <body>"; char RMEndBlock[30] = "</body> </html>"; memset(&RMark, 0, sizeof(KVRevisionMark)); KVStructInit(&RMark); RMark.pszRevSumStartBlock = RMStartBlock; RMark.pszRevSumEndBlock = RMEndBlock; RMark.bCreateSummary = TRUE; (*fpHTMLConfig)(pKVHTML, KVCFG_INCLREVISIONMARK, TRUE, &RMark))
