### Question:
DefaultXHTMLOfficeDocumentBuilder implements XHTMLOfficeDocumentBuilder { @Override public XHTMLOfficeDocument build(InputStream officeFileStream, String officeFileName, DocumentReference reference, boolean filterStyles) throws OfficeImporterException { String cleanedOfficeFileName = StringUtils.stripAccents(officeFileName); Map<String, InputStream> inputStreams = new HashMap<String, InputStream>(); inputStreams.put(cleanedOfficeFileName, officeFileStream); Map<String, byte[]> artifacts; String outputFileName = StringUtils.substringBeforeLast(cleanedOfficeFileName, ".") + ".html"; try { artifacts = this.officeServer.getConverter().convert(inputStreams, cleanedOfficeFileName, outputFileName); } catch (OfficeConverterException ex) { String message = "Error while converting document [%s] into html."; throw new OfficeImporterException(String.format(message, officeFileName), ex); } Map<String, String> params = new HashMap<String, String>(); params.put("targetDocument", this.entityReferenceSerializer.serialize(reference)); params.put("attachEmbeddedImages", "true"); if (filterStyles) { params.put("filterStyles", "strict"); } HTMLCleanerConfiguration configuration = this.officeHtmlCleaner.getDefaultConfiguration(); configuration.setParameters(params); Reader html = getReader(artifacts.remove(outputFileName)); Document xhtmlDoc = this.officeHtmlCleaner.clean(html, configuration); @SuppressWarnings("unchecked") Map<String, byte[]> embeddedImages = (Map<String, byte[]>) xhtmlDoc.getUserData("embeddedImages"); if (embeddedImages != null) { artifacts.putAll(embeddedImages); } return new XHTMLOfficeDocument(xhtmlDoc, artifacts); }  @Override XHTMLOfficeDocument build(InputStream officeFileStream, String officeFileName, DocumentReference reference,
        boolean filterStyles);  }### Answer:
