Notes

This example of a customConverter uses regular expression to remove all occurences of HTML font tags from a rich text field. This can be used to control the formatting of rich text when rendered in the browser.

The code can easily be changed to modify other parts of the HTML formatting.

<xp:inputRichText id="inputRichText1" value="#{doc.body}" readonly="true">
	<xp:this.converter>
		<xp:customConverter>
			<xp:this.getAsObject><![CDATA[#{javascript:value}]]></xp:this.getAsObject>
			<xp:this.getAsString><![CDATA[#{javascript:
				try{
					var html=value.toString();
					html=html.replace(/<(FONT|font)([ ]([a-zA-Z]+)=(\"|')[^\"\\']+(\"|'))*[^>]+>/g,"")
					html=html.replace(/(<\/FONT>|<\/font>)/g,"")
				       return html;
				}catch(e){
				       print (e);
				}}]]>
			</xp:this.getAsString>
		</xp:customConverter>
	</xp:this.converter>
</xp:inputRichText>
