Java – jtidy beautiful print custom HTML tags

I try to use jtidy to print well formed HTML generated by users:

<div class="component-holder ng-binding ng-scope ui-draggable ui-draggable-handle" data-component="cronos-datasource" id="cronos-datasource-817277">
    <datasource name="" entity="" key="" endpoint="" rows-per-page="">
        <i class="cpn cpn-datasource"></i>
    </datasource>
</div>

This is my configuration:

Tidy tidy = new Tidy();
tidy.setXHTML(true);
tidy.setIndentContent(true);
tidy.setPrintBodyOnly(true);
tidy.setTidyMark(false);
tidy.setWraplen(2000);
tidy.setDropProprietaryAttributes(false);
tidy.setDropEmptyParas(false);
tidy.setTrimEmptyElements(false);

But jtidy is deleting my angularjs data source instruction Is there any way to solve this problem?

I got this from the log:

line 1 column 191 - Error: <datasource> is not recognized!
line 1 column 191 - Warning: discarding unexpected <datasource>

Delete tidy Setxhtml (true) or set it to false and add tidy Setxmltags (true) actually solves this problem. It starts to consider user-defined tags, but it is not a good solution because jtidy starts trying to turn off self encapsulating tags

<!-- this code -->
 <img src="anythig.jpg"/>
 <div id="anyid"></div> 

 <!-- will become -->
 <img src="anythig.jpg">
     <div id="anyid"></div>
 </img>

I need a formatted text editor I can't guarantee which instructions our users will define and use It must be a generic solution that applies to any user-defined instruction

Solution

Try to set the following properties after the current configuration:

Properties props = new Properties();
props.setProperty("new-blocklevel-tags","datasource");
tidy.getConfiguration().addProps(props);

see http://tidy.sourceforge.net/docs/quickref.html#new -blocklevel-tags.
