【问题描述】：

我有以下 xslt :-

<IncidentTicket ExternalSystemName="ExternalSystemName" Company="$Company">
<xsl:if test="Incident-LastResolvedDate and Incident-LastResolvedDate != ''" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:attribute name="LastResolvedDate">
      <xsl:value-of select="Incident-LastResolvedDate" />
    </xsl:attribute>
  </xsl:if>
  <xsl:if test="Incident-ServiceType and Incident-ServiceType != ''" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:attribute name="ServiceType">
      <xsl:value-of select="'Incident'" />
    </xsl:attribute>
  </xsl:if>
<ExternalRelease>
<xsl:if test="incTest4 and incTest4 != ''" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:attribute name="TestDate">
<xsl:value-of select="incTest4" />
</xsl:attribute>
</xsl:if>
</ExternalRelease>
</IncidentTicket>

我们可以看到节点内有节点<ExternalRelease>。

当我查询属性名称“TestDate”是否存在时，:-

var isAttributeAlreadyExists = result.Descendants().Attributes("name").Where(x => x.Value == "TestDate").Any();

这总是返回 True，因为它将它放入 ExternalRelease 节点。

当我查询时，我不想使用像 ExternalRelease 这样的子节点，我只想在 IncidentTicket 中检查。

我怎样才能做到这一点？

结果内容：-

<IncidentTicket ExternalSystemName="ExternalSystemName" Company="$Company">
  <xsl:if test="Incident-LastResolvedDate and Incident-LastResolvedDate != ''" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

【参考方案1】：

使用Elements() 代替Descendants()

【讨论】：

result.Elements().Attributes("name").Where(x => x.Value == "TestDate").Any() 每次这给我错误..即使元素存在，它返回我 false

posted..请看一下

ExternalRelease 节点不是静态的，它可以包含任何名称

属性名称="TestDate"
