x:inlucde background color

[guna@ebscohost.com]

Hi,
we are including x:include inside the document, we want to change the background color of x:include content

say if href starts with s, then use x color
if href starts with r, the use y color
if href starts with any other color, then use z color


can you guide us how to implement this

Hi,

This is too complex to do with CSS selectors. In the ExtensionsBundle you have to overwrite the createAuthorStylesFilter() method and assign styles on the xi:include content nodes. Here is some code, I made some comments.

Code: Select all

  /**

   * @see ro.sync.ecss.extensions.api.ExtensionsBundle#createAuthorStylesFilter()

   */

  @Override

  public StylesFilter createAuthorStylesFilter() {



    return new StylesFilter() {

      public String getDescription() {

        return "Custom reference colors";

      }

      

      public Styles filter(Styles styles, AuthorNode authorNode) {

        if(authorNode.getName().equals("#reference")){

          //This is an artificial node which represents the referenced content.

          //Its parent is the xi:include

          //Its href value is the "href" of the xi:include made absolute

          //If you want the original value of the "href" you take this node's parent and get its href.

          AttrValue attribute = ((AuthorElement)authorNode).getAttribute("href");

          if(attribute != null) {

            String hrefVal = attribute.getValue();

            if(hrefVal.endsWith("section1.xml")) {

              styles.setProperty(Styles.KEY_BACKGROUND_COLOR, new ro.sync.exml.view.graphics.Color(40, 40, 40));

              return styles;

            } else if(hrefVal.endsWith("section2.xml")) {

              styles.setProperty(Styles.KEY_BACKGROUND_COLOR, new ro.sync.exml.view.graphics.Color(100, 100, 100));

              return styles;

            } else {

              styles.setProperty(Styles.KEY_BACKGROUND_COLOR, new ro.sync.exml.view.graphics.Color(150, 150, 150));

              return styles;

            }

          }

        }

        return null;

      }

    };

  }
