BIRT 在脚本中将 HTML 文本转换为纯文本
[英]BIRT converting HTML text to plain text in scripts
问题描述
I am attempting to convert HTML entities/tags from a database column into plain text to be displayed in a report.
我试图将 HTML 实体/标签从数据库列转换为纯文本以显示在报告中。 The report is dynamic and as such is created using scripting functions in BIRT.该报告是动态的，因此是使用 BIRT 中的脚本功能创建的。
Since there is no layout displayed I am unable to change the type of the label/text to HTML (as far as I am aware).由于没有显示布局，我无法将标签/文本的类型更改为 HTML（据我所知）。 I have tried a few things but nothing has worked properly.我尝试了几件事，但没有任何工作正常。 Here is what I am attempting to do - any advice or direction would be very appreciated.这是我正在尝试做的 - 任何建议或方向将不胜感激。 Please note I cannot include any 3rd party libraries, but can use anything that comes as fairly standard.请注意，我不能包含任何 3rd 方库，但可以使用任何相当标准的库。
function decodeHTML(html) {
var dbf = DocumentBuilderFactory.newInstance();
var builder = dbf.newDocumentBuilder();
var doc = builder.newDocument();
var txt = doc.createElement("textarea");
txt.innerHTML = html; //does not work (think this is not avaiable in Java)
return txt.value;
}
*Its worth noting - any other ideas not involving Java or DOM are also acceptable. *值得注意 - 任何其他不涉及 Java 或 DOM 的想法也是可以接受的。 This was just one of my attempts at solving this issue.这只是我解决这个问题的尝试之一。

You can use this function to escape HTML:您可以使用此函数来转义 HTML：
function escapeHTML(str){
return str.replace(/[\u00A0-\u9999<>\&]/gim, function(i) {
return '&#'+ i.charCodeAt(0)+ ';';
});
}
function escapeHTML(str){ return str.replace(/[\ -\香<>\\&]/gim, function(i) { return '&#'+ i.charCodeAt(0)+ ';'; }); } var escaped = escapeHTML("<h1>Header</h1>"); console.log(escaped); document.body.innerHTML = escaped;
<body></body>
To decode HTML entities, you can use DOMParser .要解码 HTML 实体，您可以使用DOMParser 。
function decodeHTML(str){
var doc = new DOMParser().parseFromString(str, "text/html");
return doc.documentElement.textContent;
}
function decodeHTML(str){ var doc = new DOMParser().parseFromString(str, "text/html"); return doc.documentElement.textContent; } var decoded = decodeHTML("<h1>Header</h1>"); console.log(decoded); document.body.innerHTML = decoded;
<body></body>
