删除名为 xfdf:field 的 XML 标记(带有命名空间) [英] Removing an XML tag that is named like xfdf:field (with a namespace)

问题描述

我想从 XML 文件中删除一个 XML 元素.我想删除的标签被命名为 xfdf:field.我如何在我的 xslt 中指定它?我试过了，我收到一条错误消息org.apache.xpath.domapi.XPathStylesheetDOM3Exception: Prefix must resolve to a namespace: xfdf".

I want to remove an XML element from an XML file. The tag that I want to remove is named as xfdf:field. How do I specify this in my xslt ? I tried this and I am getting an error saything "org.apache.xpath.domapi.XPathStylesheetDOM3Exception: Prefix must resolve to a namespace: xfdf ".

这是我的 xslt.

<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes" />
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*" />
        </xsl:copy>
    </xsl:template>
    <xsl:template match="xfdf:field"></xsl:template>
</xsl:stylesheet>

这是我的 xml.

推荐答案

您需要在 XSLT 文件中指定命名空间:

You need to specify the namespace in your XSLT file:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  
        xmlns:xfdf="http://ns.adobe.com/xfdf/">
