我一直在尝试使用XSLT转换XML文件,但由于某些问题,即“xmlns”,它没有转换。我,为我的生活找不到什么是错的。

XML文件:

<?xml version="1.0" encoding="utf-8"?>
<restoreCredit fpmlVersion="5-6" 
xsi:schemaLocation="http://www.fpml.org/FpML-5/pretrade d:\_Test\_PM\FpML\5.6\pretrade\fpml-main-5-6.xsd" 
xmlns="http://www.fpml.org/FpML-5/pretrade" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <header>
        <messageId messageIdScheme="http://www.test.com/fpml">4000001</messageId>
        <sentBy>Test</sentBy>
        <sendTo>SEF1</sendTo>
        <creationTimestamp>2012-07-25T08:57:00Z</creationTimestamp>
    </header>
    <parentCorrId corrIdScheme="http://www.test.com/fpml">RestoreCreditOnSEF</parentCorrId>
    <corrId corrIdScheme="http://www.test.com/fpml">4000123</corrId>
    <sqNumber>1</sqNumber>

    <party id="cb12">
        <partyId>CM1</partyId>
    </party>
    <account id="acc1">
        <accountId>account112</accountId>
    </account>
</restoreCredit>

这是XSLT文件:

<xsl:stylesheet version="1.0"

        </FpAccountIdAcc>
      </xsl:if>

    </rCredit>
  </xsl:template>
</xsl:stylesheet>

预期输出:

</restoreCredit>

预期输出仅在我删除xmlns =“http://www.fpml.org/FpML-5/pretrade”时出现

如果,在XML文件中,我向“xmlns”添加标签,例如xmlns:AAA =“http://www.fpml.org/FpML-5/pretrade” 但是我必须在不编辑XML文件的情况下对其进行转换

XML源中的元素位于xmlns="http://www.fpml.org/FpML-5/pretrade"命名空间中。您必须在样式表中声明此命名空间,为其指定前缀,并在选择或匹配XML中的元素时使用该前缀。这是一个最小化的例子:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fmpl="http://www.fpml.org/FpML-5/pretrade"
xmlns="http://www.fpml.org/FpML-5/pretrade"
exclude-result-prefixes="fmpl">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:template match="/fmpl:restoreCredit">
    <restoreCredit>
        <header>
            <FpHdMsgID>
                <xsl:attribute name="FpHdMsgIDScheme">
                    <xsl:value-of select="fmpl:header/fmpl:messageId/@messageIdScheme" />
                </xsl:attribute>
                <xsl:value-of select="fmpl:header/fmpl:messageId"/>
          </FpHdMsgID>
        </header>
    </restoreCredit>
</xsl:template>

</xsl:stylesheet>

当这个应用于您的输入示例时,结果将是:

<?xml version="1.0" encoding="utf-8"?>
<restoreCredit xmlns="http://www.fpml.org/FpML-5/pretrade">
  <header>
    <FpHdMsgID FpHdMsgIDScheme="http://www.traiana.com/fpml">4000001</FpHdMsgID>
  </header>
</restoreCredit>

重要:

请注意同一命名空间的双重声明:

xmlns:fmpl="http://www.fpml.org/FpML-5/pretrade"
xmlns="http://www.fpml.org/FpML-5/pretrade"
  • 第一个声明,指定fpml prefix的声明,是 旨在使您能够处理输入XML中的元素。

  • 第二个声明声明了一个默认命名空间 样式表本身:您在样式表中写入的任何文字元素(例如示例中的<header>)都将被放入默认名称空间。

两个名称空间相同(即具有相同的URI)的事实可以说是巧合。
