示例
此示例演示如何使用 XPath 从自定义 XML 部件获取节点。
// How to get nodes from an XML part using XPath.
// Get XML nodes.
let presentation = Api.GetPresentation();
let xmlManager = presentation.GetCustomXmlParts();
let xml = xmlManager.Add("<products><item>Laptop</item><item>Mouse</item><item>Keyboard</item></products>");
let itemNodes = xml.GetNodes('/products/item');
let slide = presentation.GetSlideByIndex(0);
slide.RemoveAllObjects();
let fill = Api.CreateSolidFill(Api.RGB(255, 111, 61));
let stroke = Api.CreateStroke(0, Api.CreateNoFill());
let shape = Api.CreateShape("rect", 300 * 36000, 130 * 36000, fill, stroke);
shape.SetPosition(608400, 1267200);
let docContent = shape.GetDocContent();
let paragraph = docContent.GetElement(0);
let run = Api.CreateRun();
run.SetFontSize(60);
let displayText = "Found " + itemNodes.length + " products:";
for (let i = 0; i < itemNodes.length; i++) {
displayText += "\n" + (i + 1) + ". " + itemNodes[i].GetText();
}
run.AddText(displayText);
paragraph.AddElement(run);
slide.AddObject(shape);
