element_getWxml
Retrieve WXML code for elements in WeChat Mini Programs, including inner or outer markup and custom component elements, to inspect and debug page structures.
Instructions
获取元素 WXML。默认获取内部 WXML(element.wxml())，设置 outer 为 true 可获取包含元素本身的 WXML(element.outerWxml())。如需获取自定义组件内部元素的 WXML，请使用 innerSelector 参数：selector 设为组件 ID 选择器(如 #my-component)，innerSelector 设为组件内部元素的选择器。

- src/tools/element.ts:64-68 (schema)Zod schema defining the input parameters for the element_getWxml tool: selector, optional innerSelector, and optional outer flag.const getElementWxmlParameters = connectionContainerSchema.extend({ selector: z.string().trim().min(1), innerSelector: z.string().trim().min(1).optional(), outer: z.boolean().optional().default(false), });
- src/tools.ts:7-13 (registration)Registration of element tools (including element_getWxml) via spreading createElementTools into the main tools array in createTools.export function createTools(manager: WeappAutomatorManager): AnyTool[] { return [ ...createApplicationTools(manager), ...createPageTools(manager), ...createElementTools(manager), ]; }
- src/index.ts:17-17 (registration)Final MCP server registration of all tools, including element_getWxml, by calling server.addTools(createTools(manager)).server.addTools(createTools(manager));
- src/tools/element.ts:70-84 (registration)Local registration of the element_getWxml tool within the createElementTools function that returns the array of element tools.export function createElementTools( manager: WeappAutomatorManager ): AnyTool[] { return [ createTapElementTool(manager), createInputTextTool(manager), createCallElementMethodTool(manager), createGetElementDataTool(manager), createSetElementDataTool(manager), createGetInnerElementTool(manager), createGetInnerElementsTool(manager), createGetElementSizeTool(manager), createGetElementWxmlTool(manager), ]; }
