我正在使用 Java 6。我的 pom 中有这个依赖项......

            <dependency>
                    <groupId>xerces</groupId>
                    <artifactId>xercesImpl</artifactId>
                    <version>2.10.0</version>
            </dependency>

我正在尝试用这一行解析 XHTML 文档

   <!--[if gte mso 9]><xml>  <w:WordDocument>   <w:View>Normal</w:View>   <w:Zoom>0</w:Zoom>   <w:TrackMoves/>   <w:TrackFormatting/>   <w:PunctuationKerning/>   <w:ValidateAgainstSchemas/>   <w:SaveIfXMLInvalid>false</w:SaveIfXMLInvalid>   <w:IgnoreMixedContent>false</w:IgnoreMixedContent>   <w:AlwaysShowPlaceholderText>false</w:AlwaysShowPlaceholderText>   <w:DoNotPromoteQF/>   <w:LidThemeOther>EN-US</w:LidThemeOther>   <w:LidThemeAsian>JA</w:LidThemeAsian>   <w:LidThemeComplexScript>X-NONE</w:LidThemeComplexScript>   <w:Compatibility>    <w:BreakWrappedTables/>    <w:SnapToGridInCell/>    <w:WrapTextWithPunct/>    <w:UseAsianBreakRules/>    <w:DontGrowAutofit/>    <w:SplitPgBreakAndParaMark/>    <w:EnableOpenTypeKerning/>    <w:DontFlipMirrorIndents/>    <w:OverrideTableStyleHps/>    <w:UseFELayout/>   </w:Compatibility>   <m:mathPr>    <m:mathFont m:val="Cambria Math"/>    <m:brkBin m:val="before"/>    <m:brkBinSub m:val="--"/>    <m:smallFrac m:val="off"/>    <m:dispDef/>    <m:lMargin m:val="0"/>    <m:rMargin m:val="0"/>    <m:defJc m:val="centerGroup"/>    <m:wrapIndent m:val="1440"/>    <m:intLim m:val="subSup"/>    <m:naryLim m:val="undOvr"/>   </m:mathPr></w:WordDocument> </xml><![endif]-->

使用此代码...

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setValidating(false);
    factory.setExpandEntityReferences(false);
    factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
    final DocumentBuilder builder = factory.newDocumentBuilder();
    final InputSource s = new InputSource(new StringReader(str));
    org.w3c.dom.Document result = builder.parse(s);

但我的解析正在死亡，但出现以下异常......

在不更改我的 XHTML 的情况下，任何人都知道如何成功解析此文档吗？

编辑根据给出的评论，我从原始问题中删除了“格式良好”一词。我仍然对如何在不更改我正在解析的文本（我无法控制）的情况下消除此异常非常感兴趣。出于这个问题的目的，您可以假设评论中的“--”是唯一违反“格式良好”一词的行为。

根据定义：

注释以“--”开头和结尾，并且不包含任何“--”。

所以不，您的 XHTML 格式不正确，因为您不能--在注释中的任何地方使用。可以用别的东西代替吗？或者可能在两者之间放置一个空格，如下所示：- -. 对于这个问题确实没有一个干净的解决方案，任何替代方案都涉及搞乱占位符、编码等。

您的文档必须至少有一个额外的“-”。可能你写过：

<!--- --> or
<!--- ---> or
<!-- ---> etc.
