XML格式的大纲解析器

本文描述与CBCGPOutlineParser和编辑控件的自动概述特性一起使用的XML文件格式，XML解析器通过调用CBCGPEditCtrl::LoadOutlineParserXMLSettings来调用。

大纲解析器使用的结构如下:

<SETTINGS>
<OUTLINE_DATA>
<IgnoreOneLineBlocks></IgnoreOneLineBlocks>
<EscapeSequences>
<EscapeSequence></EscapeSequence>
</EscapeSequences>

<BLOCKS>
<BLOCK>
<Start></Start>
<End></End>
<ReplaceString></ReplaceString>
<AllowNestedBlocks></AllowNestedBlocks>
<Ignore></Ignore>
</BLOCK>
</BLOCKS>
</OUTLINE_DATA>
/SETTINGS>

除了主要的“SETTINGS”标签外，没有强制性标签。

"OUTLINE_DATA"标签定义一般大纲解析器设置。

• IgnoreOneLineBlocks”标签定义了编辑控件是否应该将一行块视为可折叠的，默认为False。
• "EscapeSequences"标签定义了一个转义序列列表。
• "EscapeSequence"标记表示单个转义序列。
• “BLOCKS”标记用于该语言的语法定义，每个块指定大纲解析器如何找到大纲可折叠区域的规则。当您需要定义一组相同语言语法块的自动概述区域时，它很有用，对于每个块，XML解析器将调用CBCGPOutlineParser::AddBlockType。
• BLOCK”标签代表单个块
  • "Start" - defines BlockType::m_strOpen
  • "End" - defines BlockType::m_strClose
  • "ReplaceString" - defines BlockType::m_strReplace, "..." by default
  • "AllowNestedBlocks" - defines BlockType::m_bAllowNestedBlocks, "True" by default
  • "Ignore" - defines BlockType::m_bIgnore, "False" by default

C++的默认XML设置:

<SETTINGS>
<OUTLINE_DATA>
<IgnoreOneLineBlocks>True</IgnoreOneLineBlocks>
<IncludeSpaceLines>True</IncludeSpaceLines>
<EscapeSequences>
<EscapeSequence>\\\"</EscapeSequence>
</EscapeSequences>
<BLOCKS>
<BLOCK>
<Start>\\\"</Start>
<End></End>
<ReplaceString></ReplaceString>
<AllowNestedBlocks>False</AllowNestedBlocks>
<Ignore>True</Ignore>
</BLOCK>

<BLOCK>
<Start>\"</Start>
<End>\"</End>
<ReplaceString>\"\"</ReplaceString>
<AllowNestedBlocks>False</AllowNestedBlocks>
<Ignore>True</Ignore>
</BLOCK>
