将XML数据解析为Chart.js折线图-ParseXMLdataintoChart.jsLineChart

I'm trying to combine two Javascripts into one but am struggling to get it to work. I'm not sure if what I'm trying to do is possible, but I thought stackoverflow is the best place to get help.

我正在尝试将两个Javascripts合并为一个，但我正在努力让它工作。我不确定我想做的事情是否可行，但我认为stackoverflow是获得帮助的最佳场所。

The first Javascript is Chart.js, specifically the Line Chart option. The second script is an XML in HTML script by w3schools.

第一个Javascript是Chart.js，特别是折线图选项。第二个脚本是w3schools的HTML脚本XML。

What I would like to do is using an XML file to populate the data for the line chart. I modified the code accordingly, but I have only very basic knowledge of Javascript and couldn't get it to work. This is what I tried:

我想要做的是使用XML文件填充折线图的数据。我相应地修改了代码，但我只有非常基本的Javascript知识，无法让它工作。这是我试过的：

So, the idea is that the data section of the variable lineChartData is populated by getting all elements in the row data_chart_1 from the XML file data_chart.xml. Is something like this possible? How would I have to update the code to make this work?

因此，我们的想法是通过从XML文件data_chart.xml获取行data_chart_1中的所有元素来填充变量lineChartData的数据部分。这样的事情可能吗？我如何更新代码才能使其工作？

Thank you very much for your help. I hope my question was clear.

非常感谢您的帮助。我希望我的问题很明确。

var firstRow = xmlDoc.getElementsByTagName("Row")[0];
//console.log(firstRow);
var dataChart = firstRow.firstChild.nodeValue;
//console.log(dataChart);
var chartData = dataChart.split(",");
