Hi Kai,
I'm following your suggestion.

1) I have created a XSD (simple-text.xsd) starting by page you suggested:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
	<xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/>
		
	<xsd:element name="XmlContentDocSimpleTypes" type="OpenCmsXmlContentDocSimpleTypes"/>
	
	<xsd:complexType name="OpenCmsXmlContentDocSimpleTypes">
		<xsd:sequence>
			<xsd:element name="XmlContentDocSimpleType" type="OpenCmsXmlContentDocSimpleType" minOccurs="0" maxOccurs="unbounded"/>
		</xsd:sequence>
	</xsd:complexType>

	<xsd:complexType name="OpenCmsXmlContentDocSimpleType">
		<xsd:sequence>
			<xsd:element name="SimpleText" type=" TextareaWidget" />
		</xsd:sequence>
		<xsd:attribute name="language" type="OpenCmsLocale" use="required"/>
	</xsd:complexType>
</xsd:schema>

2) I have created a JSP (simple-text.jsp):

<%@ page session="false" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>

<div class="element">
<cms:contentload collector="singleFile" param="%(opencms.uri)" editable="true">

<p>
<cms:contentshow element="SimpleText" />
</p>

</cms:contentload>
</div>

3) then I have created a html file with xmlcontent type and template-elements = "simple-text.jsp ". When I try to edit it I have "An unexpected error happened, but no error message has been provided. " and error log is:

Hi Corrado,
you could create a XML Content type with just one element. This element uses the TextareaWidget type (more info: https://opencms.cse.unsw.edu.au/alkacon-documentation/documentation_xmlcontent/step3-advancedxsd.html).

Betreff: [opencms-dev] Create a txt file with fixed header/footer

Hi all,
I would like to create a template with which to allow editors to create a simple text file (.txt). Each file will have a header and footer and variabile body.

I have created the following simple code (JSP):

<%@ page session="false" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>

***HEADER***
<cms:include element="body" />
***FOOTER***

When I create a "Page with free text" the editor inserts <p></p> tags around text I'm writing but... I do not want html tags! The best would be have an editor very simple as if I choose to create a "text file".

How can I do it?

I use OpenCms 8.0.1.

Thanks

Corrado
