使用xslt

从xml中删除特定节点

我的问题有两个部分

1）使用xslt

从xml中删除specfic节点

2）一旦xslt准备就绪，这必须在运行时完成，要删除的节点值将作为参数传递

以上是xml示例 isbn数字将动态传递， 并且xslt应该能够在java代码中获取isbn数字的值作为参数，并在运行时删除特定节点并将xml转换为传递的节点。

抱歉把问题放在同一个地方 如果我单独得到答案，它会很方便

到目前为止，我已设法创建此XSLt，它返回所有值

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output method="xml" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:param name="codes"/>

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="segment">
        <xsl:choose>
            <xsl:when test="contains($codes, code/@Value)" /> <!-- Do nothing -->
            <xsl:otherwise>
                <xsl:copy>
                    <xsl:apply-templates select="@*|node()"/>
                </xsl:copy>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

Martin给出的答案有100分，而且效果很好， 我仍然有一个问题，我出于简单/安全原因给出了一个exmaple xml，但我正在使用的原始xml具有命名空间和 也就是这里提到的isbn数字不是直接因素

在应用xslt之后，请参阅下面的原始xml和转换后的xml 原始xml

如果您使用http://xsltransform.net/eiZQaG7：

Book

您可以传入包含单个ISBN编号的字符串或带有逗号分隔的ISBN编号列表的字符串，样式表只会将这些identification/isbnNumber元素复制到<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:df="urn:bbbbbbb" xmlns:stf="dddddd" exclude-result-prefixes="df stf"> <xsl:output method="xml" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:param name="isbns-to-remove" select="'CCCCCC33333333,EEEEEE555555555'"/> <xsl:template match="@*|node()" name="identity"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="df:Book"> <xsl:if test="not(contains(concat(',', $isbns-to-remove, ','), concat(',', df:BookSpec/stf:BookRefId, ',')))"> <xsl:call-template name="identity"/> </xsl:if> </xsl:template> </xsl:stylesheet> 中未包含<div>的结果中参数。

由于您现在使用命名空间发布了更复杂的XML输入示例，因此需要调整XSLT代码中的路径：

<div>
    ...
    <script type="text/javascript">
        myFunction(dynam_param1, dynam_param2);
    </script>
</div>
