Question

下载文件时出现错误：

引用了实体“nbsp”，但未声明。

我可以下载该文件，但我无法预览该文件。以下是我的代码：

var arr = ["", "", "", "", "", "", "", "", "", "", ""];
var el = document.getElementById("dem");
function updateData(a) {
    el.innerHTML = a.join('');
}

function changeData() {
    for (i = 0; i < arr.length; i++) {
        arr[i] = Math.floor(Math.random() * 2) ? "|" : "1";
    }
    updateData(arr);
}
setInterval(changeData, 500);

我尝试将<div class="bdy" > <p id="dem">AHAHHAHAHH!!!</p> </div>替换为is = new ByteArrayInputStream(articleHtml.getBytes()); DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = dbf.newDocumentBuilder(); Document doc = builder.parse(is, null); ITextRenderer renderer = new ITextRenderer(); renderer.setDocument(doc, null); renderer.layout(); try { renderer.createPDF(outputStream); } catch (com.lowagie.text.DocumentException e) { e.printStackTrace(); }。请帮我解决这个问题。

您是否尝试过将声明实体声明为？

<!DOCTYPE test [
  <!ENTITY nbsp "&#160;">
]>
<test>The Spanish word for "Spain" is "Espa&nbsp;a" Dagon his Name, Sea Monster</test>

取自The entity "nbsp" was referenced, but not declared

实体“nbsp”已被引用，但未在liferay 6.2中声明
