Calendar exports HTML tags

CalEventLocalServiceImpl.toICalVEvent() simply adds the description to the resulting iCal4j VEvent by calling new Description(event.getDescription()).

This leads to HTML markup embedded in the calendar export since the implementation of LPS-7966.

HTML markup needs to be removed from the description suring export or replaced with newlines/tabs in some cases.

The following code snippet could be an indication on what could be possibly done:

String descriptionStr = event.getDescription();
		
descriptionStr = StringUtil.trim(description);
descriptionStr = description.replaceAll("\r|\n|\t", StringPool.BLANK);
descriptionStr = description.replaceAll("(?i) ", StringPool.SPACE);
descriptionStr = description.replaceAll("(?i)<li>", "\n* ");
descriptionStr = description.replaceAll("(?i)<dd>", "\n\t");
descriptionStr = description.replaceAll("(?i)<td>", "\t");
descriptionStr = description.replaceAll("(?i)<a.+href=\"(.+)\"(?:/>|>.*</a>)", "$1");
descriptionStr = description.replaceAll("(?i)</?(?:br|p|div|h.|dt|tr)/?>(?!$)", StringPool.NEW_LINE);
descriptionStr = HtmlUtil.unescape(description);
descriptionStr = HtmlUtil.stripHtml(description);
descriptionStr = description.replaceAll("(?:\\n\\s*)+", StringPool.NEW_LINE);

Description description = new Description(descriptionStr);

In addition the HTML version of the description could be added in the X-ALT-DESC property to allow calendars like Outlook to still show the full HTML.

final XProperty altDesc = new XProperty("X-ALT-DESC", event.getDescription());
altDesc.getParameters().add(new XParameter("FMTTYPE", "text/html"));
eventProps.add(altDesc);

We have performed a short test in Outlook 2007 with this snippet.

Maybe CalEventLocalServiceImpl.importICal4j() should also do some replacing of newlines in imported events' descriptions with BR tags.

Soeren,

Thank you for your report. As part of the community verifier program I am taking a look at this issue.

[Drew Blessing (Inactive)]

I was able to reproduce this in Liferay 6.1 GA1.

Steps:
1. Create a calendar event with rich text.
2. Export the calendar event and download the .ics file.
3. Import .ics into a calendar program such as iCal.

Observe the HTML tags in the description of the event.
