由于命名空间"xmlns",无法使用XSLT转换XML

Question

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" 
xmlns="http://www.fpml.org/FpML-5/pretrade"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.fpml.org/FpML-5/pretrade d:\_test\_PM\FpML\5.6\pretrade\fpml-main-5-6.xsd" 
>

<xsl:output method ="xml" indent="yes"/>

  <!-- NOTE: All tags have been checked if present, if not , the tags will not be shown in the output -->
  <xsl:strip-space elements= "*"/>

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

  <xsl:template match="rCredit">
    <rCredit>
      <xsl:if test="header">
        <!-- Header  -->
        <header>
          <FpHdMsgID>
            <xsl:attribute name = "FpHdMsgIDScheme">
              <xsl:value-of select = "header/messageId/@messageIdScheme" />
            </xsl:attribute>
            <xsl:value-of select = "header/messageId"/>
          </FpHdMsgID>

          <FpHdSentBy>
            <xsl:value-of select = "header/sentBy" />
          </FpHdSentBy>

          <FpHdSentTo>
            <xsl:value-of select="header/sendTo" />
          </FpHdSentTo>

          <FpHdCreateTime>
            <xsl:value-of select= "header/creationTimestamp" />
          </FpHdCreateTime>

          <xsl:if test = "header/expiryTimeStamp">
            <FpHdExpTime>
              <xsl:value-of select= "header/expiryTimeStamp" />
            </FpHdExpTime>
          </xsl:if>
        </header>
      </xsl:if>

      <!-- parentCorrId -->
      <xsl:if test="parentCorrId">
        <FpParentCorID>
          <xsl:attribute name = "FpParentCorIDCorSch">
            <xsl:value-of select = "parentCorrId/@corrIdScheme" />
          </xsl:attribute>
          <xsl:value-of select = "parentCorrId"/>
        </FpParentCorID>
      </xsl:if>

      <!-- corrId -->
      <xsl:if test="corrId">
        <FpCorID>
          <xsl:attribute name = "FpCorIDSch">
            <xsl:value-of select = "corrId/@corrIdScheme" />
          </xsl:attribute>
          <xsl:value-of select = "corrId"/>
        </FpCorID>
      </xsl:if>

      <!-- sqNumber -->
      <xsl:if test="sqNumber">
        <FpSeqNum>
          <xsl:value-of select="sqNumber"/>
        </FpSeqNum>
      </xsl:if>

      <!-- party -->
      <xsl:if test="party">
        <FpPartyID>
          <xsl:value-of select = "party/@id" />
        </FpPartyID>

        <FpPartyIDValue>
          <xsl:value-of select = "party/partyId" />
        </FpPartyIDValue>
      </xsl:if>

      <!-- account -->
      <xsl:if test="account">
        <FpAccountId>
          <xsl:value-of select="account/@id"/>
        </FpAccountId>

        <FpAccountIdAcc>
          <xsl:value-of select="account/accountId"/>
        </FpAccountIdAcc>
      </xsl:if>

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

预期输出量:

<?xml version="1.0" encoding="UTF-8"?>
<restoreCredit xmlns="http://www.fpml.org/FpML-5/pretrade" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <header>
        <FpHdMsgID FpHdMsgIDScheme="http://www.test.com/fpml">4000001</FpHdMsgID>
        <FpHdSentBy>Test</FpHdSentBy>
        <FpHdSentTo>SEF1</FpHdSentTo>
        <FpHdCreateTime>2012-07-25T08:57:00Z</FpHdCreateTime>
    </header>
    <FpParentCorID FpParentCorIDCorSch="http://www.test.com/fpml">RestoreCreditOnSEF</FpParentCorID>
    <FpCorID FpCorIDSch="http://www.test.com/fpml">4000123</FpCorID>
    <FpSeqNum>1</FpSeqNum>
    <FpPartyID>cb12444</FpPartyID>
    <FpPartyIDValue>CM1</FpPartyIDValue>
    <FpAccountId>acc1</FpAccountId>
    <FpAccountIdAcc>account1</FpAccountIdAcc>
</restoreCredit>

结果输出:

<?xml version="1.0" encoding="UTF-8"?>
<restoreCredit xmlns="http://www.fpml.org/FpML-5/pretrade" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" fpmlVersion="5-6" xsi:schemaLocation="http://www.fpml.org/FpML-5/pretrade d:\_test\_PM\FpML\5.6\pretrade\fpml-main-5-6.xsd">
    <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="c3321">      
        <partyId>CM1</partyId>
    </party>
    <account id="acc1">
        <accountId>account12</accountId>  
    </account>
</restoreCredit>

只有当我删除xmlns ="http://www.fpml.org/FpML-5/pretrade"时才会出现预期的输出

如果,在XML文件中,我将标签添加到"xmlns",例如xmlns:AAA ="http://www.fpml.org/FpML-5/pretrade"但是我必须在不编辑XML的情况下对其进行转换档案.

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:

请注意相同名称空间的双重声明:

xmlns:fmpl="http://www.fpml.org/FpML-5/pretrade"
xmlns="http://www.fpml.org/FpML-5/pretrade"

• 第一个声明是指定的声明,fpml prefix旨在使您能够处理输入XML中的元素.

• 第二个声明声明了样式表本身的默认命名空间:您在样式表中写入的任何文字元素(例如<header>示例中的)将被放入默认命名空间.

两个名称空间相同(即具有相同的URI)的事实可以说是巧合.
