该ui文件读取第28行72列时出错,请改正并给出修改后的ui文件

### 修正 Qt UI 文件中的错误并提供修改后的完整版本
在 `.ui` 文件中,第28行72列的错误通常意味着该位置存在 XML 格式问题。由于 `.ui` 文件本质上是 XML 文档,因此必须遵循严格的语法规范,例如标签闭合、属性值使用引号包裹、避免非法字符等。
#### 常见错误原因及修复方法:
- **未正确闭合的标签**:确保所有开始标签都有对应的结束标签。
- **属性值未加引号**:属性值必须用双引号或单引号包裹。
- **非法字符未转义**:如 `<` 应替换为 `<`,`>` 替换为 `>`,`&` 替换为 `&`。
- **布局嵌套错误**:确保控件和布局的结构合法,没有不合理的嵌套。
假设原始 `.ui` 文件中第28行内容如下(包含错误):
```xml
<property name="text"><string>Save & Exit</string></property>
```
该行中的 `&` 是非法 XML 字符,会导致解析失败。正确的写法应为:
```xml
<property name="text"><string>Save & Exit</string></property>
```

### 修改后的完整 `.ui` 文件示例
以下是一个经过格式修正的完整 `.ui` 文件示例,适用于一个简单的主窗口界面:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
<class>MainWindow</class>
<widget class="QMainWindow" name="MainWindow">
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>400</width>
<height>300</height>
</rect>
</property>
<property name="windowTitle">
<string>MainWindow</string>
</property>
<widget class="QWidget" name="centralWidget">
<layout class="QVBoxLayout" name="verticalLayout">
<item>
<widget class="QPushButton" name="pushButton">
<property name="text">
<string>Save & Exit</string>
</property>
</widget>
</item>
</layout>
</widget>
</widget>
<resources/>
<connections/>
</ui>
```
此文件修复了 XML 中的非法字符问题,并确保所有标签和属性格式符合标准。

### 验证方式
为了进一步确认该文件是否可被正确读取,可以采用以下方法进行验证:
- 使用 `xmllint` 工具检查 XML 合法性:
```bash
xmllint --noout modified.ui
```
- 使用 Qt 的 `uic` 工具尝试生成头文件:
```bash
uic modified.ui -o ui_modified.h
```
- 在 Qt Creator 中打开 `.ui` 文件,查看是否有错误提示或渲染异常。
