title: XML 读书笔记 | ||

XML 文件是由标记及其所标记的内容构成的文本文件,与 HTML 文件不同的是,这些标记可自由定义,其目的是使得 Internet 网络上的数据交互更方便,让文件的内容更加通俗易懂。 | ||
|

|
||
## 1. XML 规范 | ||
|
||
 | ||
|
||
* XML 声明 | ||
1. Version 属性 | ||
2. Encoding 属性 | ||
3. Standalone 属性 | ||
* XML 标记 | ||
1. 空标记 | ||
2. 非空标记 | ||
3. 标记名称区分大小写 | ||
4. 根标记 | ||
* CDATA 段 | ||
CDATA 段中的内容不被解析,CDATA 段不支持嵌套 | ||
* 属性 | ||
属性区分大小写 | ||
使用属性的原则:不要因为属性的频繁使用破坏 XML 的数据结构 | ||
* 注释 | ||
<! -- 注释 --> | ||
* 命名空间 | ||
## 2. 有效的 XML 文件 | ||
一个规范的 XML 文件如果和某个 DTD 文件相关联,并遵守该 DTD 文件规定的约束条件,就称为有效的 XML 文件。 | ||
|
||
DTD(Document Type Definition) 文件是有着特殊结构的文件,简单的说,DTD 文件是由元素所构成的文本文件。在 DTD 文件中,用关键字 `ELEMENT` 来定义一个元素,格式如下: | ||
|
||
```xml | ||
<!-- 商店营业时间标记中只可以由若干个名字为商店的子标记 --> | ||
<!ELEMENT 商店营业时间 (商店*)> | ||
<!-- 商店的标记恰好顺序为商店名称、开门时间、关门时间,而且约束名称为商店的标记包含的内容不可以含有可显示的字符(允许含有空格、回车等空白类字符) --> | ||
<!ELEMENT 商店 (商店名称,开门时间,关门时间)> | ||
<!-- 约束标记中只能是文本数据,不可以包含子标记 --> | ||
<!ELEMENT 商店名称 (#PCDATA)> | ||
<!ELEMENT 开门时间 (#PCDATA)> | ||
<!ELEMENT 关门时间 (#PCDATA)> | ||
``` | ||
|
||
### 2.1. XML 文件与 DTD 文件相关联 | ||
|
||
* SYSTEM 格式 `<DOCTYPE 根标记名称 SYSTEM "DTD 文件 URL">` | ||
* PUBLIC 格式 `<DOCTYPE 根标记名称 PUBLIC "正式公用标识符" "DTD 文件 URL">` | ||
|
||
正式公用标识符(Formal Public Identifier, FPI)的格式为 “-ISO认证//单位名称//DTD说明//所用语言” | ||
|
||
如果 URI 是一个文件名,该 DTD 文件必须和当前 XML 文件在同一目录中,否则 URI 是一个可访问的 URL 资源。 | ||
|
||
DTD 文档类型的声明必须写在 XML 声明后。 | ||
|
||
### 2.2. DTD 完整性 | ||
|
||
* ELEMENT 标记约束 | ||
```xml | ||
<!ELEMENT 标记名称 标记的约束条件> | ||
``` | ||
* ATTLIST 属性约束列表 | ||
|
||
```xml | ||
<!ATTLIST 标记名称 | ||
属性名称 属性类型 默认值情况 | ||
属性名称 属性类型 默认值情况 | ||
... | ||
> | ||
``` | ||
|
||
#### 属性类型 | ||
|
||
|属性类型|约束意义 | ||
|-|- | ||
|CDATA|字符串 | ||
|Enumerated|枚举值 | ||
|NMTOKEN|属性中不能含有空格 | ||
|NMTOKENS|属性中可以含有空格 | ||
|ID|唯一类型,默认值情况只能是`#REQUIRED,#IMPLIED`,一个标记中只能有一个 ID 属性类型 | ||
|IDREF|ID 引用属性类型,其内容只能是已有的 ID 属性中的值 | ||
|IDREFS|ID 引用属性类型的集合,可以添加多个 ID 属性 | ||
|
||
1. Enumerated | ||
|
||
```xml | ||
<!ATTLIST 标记名称 属性名称 (属性值1|属性值2|...|属性值n) 默认值情况> | ||
``` | ||
|
||
#### 默认值情况 | ||
|
||
|默认值情况|约束意义 | ||
|-|- | ||
|字符串|标记必须有该属性,且有默认值 | ||
|#IMPLIED|标记可以没有该属性,没有默认值 | ||
|#REQUIRED|标记必须有该属性,没有默认值 | ||
|#FIXED"字符串"|标记可以没有该属性,但如果有该属性,那么属性值固定不变 | ||
|
||
### 内部 DTD | ||
|
||
```xml | ||
<!DOCTYPE 根标记名称 [ | ||
内部 DTD 内容 | ||
]> | ||
``` | ||
|
||
内部 DTD 与 外部 DTD 混合 | ||
|
||
```xml | ||
<!DOCTYPE 根标记名称 SYSTEM "外部 DTD 的 URI" [ | ||
内部 DTD 内容 | ||
]> | ||
<!DOCTYPE 根标记名称 PUBLIC "正式公用标识符" "外部 DTD 的 URI" [ | ||
内部 DTD 内容 | ||
]> | ||
``` | ||

|
||
## 多屏如何设置数位板控制哪个屏幕 | ||
|
||
1. 查看显示器信息 `xrandr` | ||
|
||
```plain | ||
Screen 0: minimum 320 x 200, current 3840 x 1200, maximum 16384 x 16384 | ||
eDP-1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 302mm x 189mm | ||
1920x1200 60.00*+ 60.00 | ||
... | ||
320x240 60.00 | ||
360x202 60.00 | ||
320x180 60.00 | ||
HDMI-1 disconnected (normal left inverted right x axis y axis) | ||
DP-1 disconnected (normal left inverted right x axis y axis) | ||
HDMI-2 disconnected (normal left inverted right x axis y axis) | ||
DP-2 disconnected (normal left inverted right x axis y axis) | ||
HDMI-3 disconnected (normal left inverted right x axis y axis) | ||
DP-3 connected primary 1920x1080+1920+0 (normal left inverted right x axis y axis) 345mm x 194mm | ||
1920x1080 59.93*+ 60.00 59.94 | ||
1600x900 60.00 | ||
1280x720 60.00 59.94 | ||
1024x768 60.00 | ||
800x600 60.32 | ||
640x480 60.00 59.94 | ||
DP-4 disconnected (normal left inverted right x axis y axis) | ||
``` | ||
|
||
可以看到目前检索到 `eDP-1`, `DP-3` 两个屏幕 | ||
|
||
2. 执行 `xsetwacom` 命令设置数位板参数 | ||
|
||
‵‵‵plain | ||
Usage: xsetwacom [options] [command [arguments...]] | ||
Options: | ||
-h, --help - usage | ||
-v, --verbose - verbose output | ||
-V, --version - version info | ||
-d, --display "display" - override default display | ||
-s, --shell - generate shell commands for 'get' | ||
-x, --xconf - generate xorg.conf lines for 'get' | ||
|
||
Commands: | ||
--list devices - display detected devices | ||
--list parameters - display supported parameters | ||
--list modifiers - display supported modifier and specific keys for keystrokes | ||
--set "device name" parameter [values...] - set device parameter by name | ||
--get "device name" parameter [param...] - get current device parameter(s) value by name | ||
‵‵‵ | ||
|
||
1. `xsetwacom --list devices` 检索数位板设备 | ||
|
||
```plain | ||
GAOMON GAOMON_M6 Pen stylus id: 16 type: STYLUS | ||
GAOMON GAOMON_M6 Pad pad id: 17 type: PAD | ||
GAOMON GAOMON_M6 Touch Ring pad id: 22 type: PAD | ||
GAOMON GAOMON_M6 stylus id: 23 type: STYLUS | ||
GAOMON GAOMON_M6 eraser id: 24 type: ERASER | ||
``` | ||
|
||
2. `xsetwacom set 'GAOMON GAOMON_M6 Pen stylus' MapToOutput DP-3` 完成设置 |
