XML格式的大綱解析器

立即下載BCGControlBar Professional Edition for MFC

本文描述與CBCGPOutlineParser和編輯控件的自動概述特性一起使用的XML文件格式，XML解析器通過調(diào)用CBCGPEditCtrl::LoadOutlineParserXMLSettings來調(diào)用。

大綱解析器使用的結(jié)構(gòu)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”標簽外，沒有強制性標簽。

"OUTLINE_DATA"標簽定義一般大綱解析器設(shè)置。

• IgnoreOneLineBlocks”標簽定義了編輯控件是否應(yīng)該將一行塊視為可折疊的，默認為False。
• "EscapeSequences"標簽定義了一個轉(zhuǎn)義序列列表。
• "EscapeSequence"標記表示單個轉(zhuǎn)義序列。
• “BLOCKS”標記用于該語言的語法定義，每個塊指定大綱解析器如何找到大綱可折疊區(qū)域的規(guī)則。當您需要定義一組相同語言語法塊的自動概述區(qū)域時，它很有用，對于每個塊，XML解析器將調(diào)用CBCGPOutlineParser::AddBlockType。
• BLOCK”標簽代表單個塊
  • "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
