Example 1 with LazyURLInputStream

use of org.eclipse.wst.xml.core.internal.validation.core.LazyURLInputStream in project webtools.sourceediting by eclipse.

the class DTDParser method resolveEntity.

public InputSource resolveEntity(String publicId, String systemId) throws SAXException {
    InputSource result = null;
    URIResolver idResolver = URIResolverPlugin.createResolver();
    String logicalURI = idResolver.resolve(currentDTD.getName(), publicId, systemId);
    // bug 113537, ensure physical resolution gets done here
    // right before we attempt to open a stream
    String physicalURI = idResolver.resolvePhysicalLocation(currentDTD.getName(), publicId, logicalURI);
    result = new InputSource(logicalURI);
    if (// $NON-NLS-1$
    !(physicalURI == null || physicalURI.equals("") || URIHelper.hasProtocol(physicalURI))) {
