displaytag surpress HTML format

I am working on an application in Java. I need to take the formated HTML data from an object and display it in a displaytag constructed table. However, it seems like by default, displaytag supress the formatting by escapeHTML the content so my format won't display properly.

Like I used the formatted data to highlight the matching search words in tag: <SPAN style='background-color:yellow;'></SPAN>. The infomation displayed in the search result was literal syntax. instead of the yellow background of the word.

How can I unescape the HTML so it can display the highlighted background?

I am ready tried to use the escapeXml attribute. However, the app failed due to invalid attributes.

Thanks,

That's odd. As per displaytag documentation XML escaping is by default disabled. Are you sure that you don't have escapeXml="true" somewhere in the tags?

Another cause could be that you're using JSTL <c:out> tag to display individual values. It does by default escape XML. You can disable it by adding escapeXml="false" attribute to the tag.

Do I understand correctly that you want to un-escape escaped HTML code? You can do it something like this:

public static String unescapeHtml(final String input){
    return input
        .replace("&lt;", "<")
        .replace("&gt;", ">")
        .replace("&amp;", "&")
        .replace("&quot;", "\"");
}
