 ### 6.2 作业文件格式
+作业文件使用 XML 格式（根元素为 `VBfiles`），由 `PicSceneLoader` 读写。要点如下：

-作业文件使用XML格式（VBfiles结构），保存场景内容和打印设置：
+- 根元素: `<VBfiles Version="1.0">`（保存时会写入 `Version` 属性及一个简单的 DOCTYPE）。
+- 每个图元为一个 `<VBfile>` 节点，常见子元素：
+  - `<pointer_x>` / `<pointer_y>`: 图元位置（浮点数）
+  - `<Condition>`: 特殊条件标志，0/1
+  - `<CatchStartValue>` / `<CatchValue>`: 与 Catch 相关的计数器起始/当前值（整数）
+  - `<itemAttrs ... />`: 图元属性以属性集合的形式保存（见下），`PicSceneLoader` 通过属性解析并传给具体图元对象
+  - `<html_src>`: 包裹图元 HTML 表示的 CDATA（编辑器中使用的 HTML 内容）
+
+示例（简化）：

 ```xml
-<VBfiles>
-    <!-- 打印设置 -->
-    <PrintSettings timeTriggerPrintMode="0" triggerInterval="90" ... />
-    <!-- 文本图元 -->
-    <VBfile>
-        <pointer_x>55</pointer_x>

-        <itemAttrs sourceType="1" dir="0" letterSpace="1" fontFamilay="WenQuanYi7" source="FGJ" ... />
-    </VBfile>
-    <!-- 日期图元 -->
-    <VBfile>
-        <pointer_x>55</pointer_x>
-        <pointer_y>0</pointer_y>
-        ...
-        <itemAttrs sourceType="3" datetimePattern="HH:mm:ss" ... />
-        </VBfile>
-    <!-- 计数器图元 -->
-    <VBfile>

-    <!-- 图片图元 -->
-    <VBfile>
-        <pointer_x>0</pointer_x>
-        <pointer_y>0</pointer_y>
-        ...
-        <itemAttrs sourceType="2" dir="0" source="/home/plg/doc/scene.png" ... />
-    </VBfile>
+<VBfiles Version="1.0">
+  <VBfile>
+    <pointer_x>55</pointer_x>
+    <pointer_y>0</pointer_y>
+    <Condition>0</Condition>
+    <CatchStartValue>-1</CatchStartValue>
+    <CatchValue>-1</CatchValue>
+    <itemAttrs sourceType="1" dir="0" letterSpace="1" fontFamilay="WenQuanYi7" source="FGJ" />
+    <html_src><![CDATA[...item html...]]></html_src>
+  </VBfile>
+  <!-- 更多 VBfile ... -->
+  <!-- PrintSettings 以属性形式保存在一个空元素中 -->
+  <PrintSettings timeTriggerPrintMode="0" triggerInterval="90" ... />
 </VBfiles>
 ```

+其他细节：
+- `itemAttrs` 中常见属性由各图元实现 `saveAttrs` / `setAttrs` 控制，通用属性包括 `sourceType`（必有）、`dir`、`boldMultiple`、`colorReversal`（"true"/"false"）、`letterSpace`、`fontFamilay`（注意拼写）以及 `source`（图元内容或图片路径）等。
+- `html_src` 使用 CDATA 保存 `toHtml()` 的内容，加载时会把 CDATA 拼接并通过 `setHtml()` 恢复。
+- `PrintSettings` 由 `PrintSettingModel::saveToXml`/`loadFromXml` 通过属性读写打印相关配置（保存时作为空元素写出属性）。`PicSceneLoader` 在解析 `VBfiles` 时会识别 `PrintSettings`（位置可以在文件中任意出现，保存实现默认写在所有 `<VBfile>` 之后）。
+- 图元类型（`sourceType`）的数值映射（见 `scene/pictextitem.h`）：
+  - `0` = `UNKNOWN`
+  - `1` = `TEXT`
+  - `2` = `IMAGE`
+  - `3` = `DATETIME`
+  - `4` = `SCHEDULE_SHIFT`
+  - `5` = `CODE`（一维/二维码）
+  - `6` = `COUNTER`
+
+该节已根据 `scene/PicSceneLoader.cpp` 的实际实现和 `Printsetting.cpp` 中的读写逻辑做了校正（包含 `Condition`/`Catch*` 字段、`Version` 属性、`html_src` CDATA、以及 `PrintSettings` 的属性化保存）。
