请注意:-相同的XML在draw.io上起作用，并且我无法捕获代码中的错误，因此在此方面提供的任何帮助将不胜感激。

我遇到了同样的麻烦，因为我找不到将xml解码为图形模型的有效方法。但是，这里有一个可用的解决方法:
function parseXmlToGraph(xmlDoc, graph) {
const cells = xmlDoc.documentElement.children[0].children
const parent = graph.getDefaultParent()
for (let i = 0; i < cells.length; i++) {
const cellAttrs = cells[i].attributes
if (cellAttrs.vertex) { // is vertex
const vertexName = cellAttrs.value.value
const vertexId = Number(cellAttrs.id.value)
const geom = cells[i].children[0].attributes
const xPos = Number(geom.x.value)
const yPos = Number(geom.y.value)
const height = Number(geom.height.value)
const width = Number(geom.width.value)
graph.insertVertex(parent, vertexId, vertexName, xPos, yPos, width, height)
} else if (cellAttrs.edge) { //is edge
const edgeName = cellAttrs.value.value
const edgeId = Number(cellAttrs.id.value)
const source = Number(cellAttrs.source.value)
const target = Number(cellAttrs.target.value)
graph.insertEdge(parent, edgeId, edgeName,
graph.getModel().getCell(source),
graph.getModel().getCell(target)
)
}
}
}
使用so就像(假设您有一张图):
const doc = mxUtils.parseXml(myXmlString) //yields xml object
parseXmlToGraph(doc, graph)

正如nbatolov's comment指出的那样，问题在于运行时窗口(全局对象)中没有这样的mx *函数，例如，在您的情况下，显然窗口缺少某些函数，例如mxGraph()，mxGraphModel()，mxCodec ()， 等等。
然后，您可以将它们添加到窗口中，然后使用以下命令运行mxCodec的解码功能
window.['mxCodec'] = mxgraph.mxCodec
其中mxgraph是您使用mxGraph的函数和对象的起点。
