我的xml文档中有projectDetails节点，它是从java jdom api创建的，节点内的数据来自数据库。
问题在于描述字段，它以 html 形式存储在数据库中。当我将其添加到 <descriptionDetails /> 中时元素，并使用 Java 的转换类对其进行转换，它会转义所有 html 标签。
是否有可能获得像其余标签一样的 Html 代码作为descriptionDetails 的子级并且未转义。
<projectDetails label="label.projectDetails">

</projectDetails最佳答案
您可以使用 https://docs.oracle.com/javase/8/docs/api/javax/xml/transform/TransformerFactory.html#newTransformer-javax.xml.transform.Source- 创建，而不是使用带有 newInstance().newTransformer() 的默认 Transformer来自样式表的一个，例如
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="descriptionDetails/text()">
<xsl:value-of select="." disable-output-escaping="yes"/>
</xsl:template>
</xsl:stylesheet>
用作源。

但请注意，转义的 HTML 包含例如实体引用 ，它会将您的输出转换为格式不正确的 XML，因为该实体未在 XML 中预定义。
