使用 SaxonJS 时,我能够验证它是否产生与 Saxon 相同的输出,但需要注意一点。SaxonJS 似乎会为每个元素发出命名空间属性,即使它们不是必需的。我尝试调整exclude-result-prefixes
,但这没有效果。

SaxonJS.Transform 上的回调是
var transformCallback = (fragment: DocumentFragment) => {
// have to convert to string?
var div = document.createElement('div');
div.appendChild(fragment.cloneNode(true));
// replace existing output content
that.outputText(div.innerHTML);
}
