Container of document objects

Description

Use an object of the mlreportgen.dom.Container class to to create a container element. Use the mlreportgen.dom.Container.append method to append document elements to the container. Use an mlreportgen.dom.Container object in a report to apply formats to all of the children of the container.

In HTML output, a Container object generates an HTML element of the type specified by its HTMLTag property and containing HTML elements corresponding to its Document Object Model (DOM) contents. For example, a Container object with the HTMLTag property div and that contains the text Hello World generates this markup:

<div><p><span>Hello World</span></p></div>

The generated HTML container element has the class and style properties specified by the Container object StyleName and Style properties, respectively. The rules of HTML CSS format inheritance assure that the generated children of the Container object inherit the formats specified by the Container object Style and StyleName properties. For example, if the Container object specifies red as its text color and none of its text children specify a color, the text children are colored red.

For Microsoft® Word and PDF report output, a Container object simulates container format inheritance, applying the formats specified by the Container object Style attribute to each child, unless overridden by the child, and then appending the child to the output. Word and PDF output ignore the HTMLTag and StyleName properties of the Container object.

Tip

You can use mlreportgen.dom.Container or mlreportgen.dom.Group objects to produce collections of document elements.

  • Use a container object to apply format inheritance to a set of objects and to create HTML container elements not otherwise supported by the DOM, such as div, section, and article.

  • Use a group object to append the same content in multiple places in a document without cloning the group.

To see what DOM objects you can append an mlreportgen.dom.Container object to, see Append mlreportgen.dom.Container object to DOM class object.

The mlreportgen.dom.Container class is a handle class.

HTML tag name of container, specified as a character vector or string scalar. The name must be an HTML element, such as "div", "section", or "article".

Note

Microsoft Word output ignores the HTML tag name.

Data Types: char | string

Name of stylesheet-defined style, specified as a character vector or string scalar. The style name is the name of a style specified in the style sheet of the document or document part to which this element is appended. The specified style defines the appearance of this element in the output document unless the formats specified by the Style property of this element override it. To learn more about using style sheets, see Use Style Sheet Styles.

Note

Microsoft Word reports ignore style names that are not defined in the document template. For more information on Microsoft Word templates, see Templates for DOM API Report Programs.

Data Types: char | string

Format specification for this document element object, specified as a cell array of DOM format objects. The formats specified by this property override corresponding formats specified by the StyleName property of this element. Formats that do not apply to this document element object are ignored.

Attributes:

Data Types: cell

Parent of this object, specified as a document element object. A document element must have only one parent.

Attributes:

Tag, specified as a character vector or string scalar. The DOM API generates a session-unique tag as part of the creation of this object. The generated tag has the form CLASS:ID, where CLASS is the object class and ID is the value of the Id property of the object. Use this value to help identify where an issue occurs during document generation.

Attributes:

Data Types: char | string

Object identifier, specified as a character vector or string scalar. The DOM API generates a session-unique identifier when it creates the document element object.

Open Script

Create a container object. Word output ignores the HTML container element tag (in this example, the div tag).

import mlreportgen.dom.*;
rpt = Document('MyReport','docx');

c = Container();

Color all of the container text red.

c.Style = {Color('red')};

Append content to the container and append the container to the report.

append(c,Paragraph('Hello'));
append(c,Table(magic(5)));
append(rpt,c);

Close and generate the report.

close(rpt);
rptview(rpt.OutputPath);

Create a container object. 

import mlreportgen.dom.*;
rpt = Document("MyReport","docx");
 
c = Container();

Append content to the container and append the container to the report.

append(c,Paragraph("Hello"));
append(c,Table(magic(5)));
append(rpt,c);

Close and generate the report.

close(rpt);      
rptview(rpt.OutputPath);

Create a container object. Microsoft Word output ignores the HTML container element tag (in this example, the div tag).

import mlreportgen.dom.*;
rpt = Document("MyReport","docx");
 
c = Container();

Color all of the text in this container red.

c.Style = {Color("red")};

Append content to the container and append the container to the report.

append(c,Paragraph("Hello"));
append(c,Table(magic(5)));
append(rpt,c);

Clone the container.

clonedC = clone(c);

Append the cloned container to the report.

append(rpt,clonedC);

Close and generate the report.

close(rpt);      
rptview(rpt.OutputPath);
