Example 5 with CMElementDeclaration

use of org.eclipse.wst.xml.core.internal.contentmodel.CMElementDeclaration in project webtools.sourceediting by eclipse.

the class HTMLFormatter method canFormatChild.

/**
 */
protected boolean canFormatChild(Node node) {
    while (node != null) {
        if (node.getNodeType() != Node.ELEMENT_NODE)
            return true;
        CMElementDeclaration decl = getElementDeclaration((Element) node);
        if (decl != null) {
            if (decl.getContentType() == CMElementDeclaration.CDATA)
                return false;
            if (decl.supports(HTMLCMProperties.SHOULD_KEEP_SPACE)) {
                boolean shouldKeepSpace = ((Boolean) decl.getProperty(HTMLCMProperties.SHOULD_KEEP_SPACE)).booleanValue();
