如何使用AvalonEdit编辑XML文件

Question

我想在我的应用程序中包含一个XML编辑器-类似于VS的具有自动着色等功能的XML编辑器。

AvalonEdit听起来是个不错的解决方案。

但是，AvalonEdit提供了C#语法的示例，而不是XML语法。有没有XML语法的示例？

Answer 1

只需在您的XAML中使用SyntaxHighlighting="XML"：

xmlns:avalonedit="http://icsharpcode.net/sharpdevelop/avalonedit"
...
<StackPanel>
    <avalonedit:TextEditor SyntaxHighlighting="XML"/>
</StackPanel>

Answer 2

您所要做的就是更改Avalon中的xshd文件，以将其更改为所需的语言要求。Link已经在SharpDevelop Git中提供了许多公共语言语法突出显示功能

对于XML，xshd文件如下所示：

<SyntaxDefinition name="XML"     extensions=".xml;.xsl;.xslt;.xsd;.manifest;.config;.addin;.xshd;.wxs;.wxi;.wxl;.proj;.csproj;.vbproj;.ilproj;.booproj;.build;.xfrm;.targets;.xaml;.xpt;.xft;.map;.wsdl;.disco;.ps1xml;.nuspec" xmlns="http://icsharpcode.net/sharpdevelop/syntaxdefinition/2008">
<Color foreground="Green" name="Comment" exampleText="&lt;!-- comment --&gt;" />
<Color foreground="Blue" name="CData" exampleText="&lt;![CDATA[data]]&gt;" />
<Color foreground="Blue" name="DocType" exampleText="&lt;!DOCTYPE rootElement&gt;" />
<Color foreground="Blue" name="XmlDeclaration" exampleText='&lt;?xml version="1.0"?&gt;' />
<Color foreground="DarkMagenta" name="XmlTag" exampleText='&lt;tag attribute="value" /&gt;' />
<Color foreground="Red" name="AttributeName" exampleText='&lt;tag attribute="value" /&gt;' />
<Color foreground="Blue" name="AttributeValue" exampleText='&lt;tag attribute="value" /&gt;' />
<Color foreground="Teal" name="Entity" exampleText="index.aspx?a=1&amp;amp;b=2" />
<Color foreground="Olive" name="BrokenEntity" exampleText="index.aspx?a=1&amp;b=2" />

<RuleSet>
    <Span color="Comment" multiline="true">
        <Begin>&lt;!--</Begin>
        <End>--&gt;</End>
    </Span>
    <Span color="CData" multiline="true">
        <Begin>&lt;!\[CDATA\[</Begin>
        <End>]]&gt;</End>
    </Span>
    <Span color="DocType" multiline="true">
        <Begin>&lt;!DOCTYPE</Begin>
        <End>&gt;</End>
    </Span>
    <Span color="XmlDeclaration" multiline="true">
        <Begin>&lt;\?</Begin>
        <End>\?&gt;</End>
    </Span>
    <Span color="XmlTag" multiline="true">
        <Begin>&lt;</Begin>
        <End>&gt;</End>
        <RuleSet>
            <!-- Treat the position before '<' as end, as that's not a valid character
                 in attribute names and indicates the user forgot a closing quote. -->
            <Span color="AttributeValue" multiline="true" ruleSet="EntitySet">
                <Begin>"</Begin>
                <End>"|(?=&lt;)</End>
            </Span>
            <Span color="AttributeValue" multiline="true" ruleSet="EntitySet">
                <Begin>'</Begin>
                <End>'|(?=&lt;)</End>
            </Span>
            <Rule color="AttributeName">[\d\w_\-\.]+(?=(\s*=))</Rule>
            <Rule color="AttributeValue">=</Rule>
        </RuleSet>
    </Span>
    <Import ruleSet="EntitySet"/>
</RuleSet>

<RuleSet name="EntitySet">
    <Rule color="Entity">
        &amp;
        [\w\d\#]+
        ;
    </Rule>

    <Rule color="BrokenEntity">
        &amp;
        [\w\d\#]*
        #missing ;
    </Rule>
</RuleSet>
</SyntaxDefinition>
