通过XSLT循环

Question

我有这个输入XML：

<?xml version='1.0' encoding='UTF-8'?>
<Document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn-sample">

          </TransactionDetails>
        </EntryDtls>
      </Entry>
    </Statement>
  </CustomerRecord>
</Document>

然后我有了这个XSLT：

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

  <xsl:template match="/urn:Document">
    <Root>
      <xsl:apply-templates select="/urn:Document/urn:CustomerRecord/urn:Statement" />
    </Root>
  </xsl:template>

  <xsl:template match="/urn:Document/urn:CustomerRecord/urn:Statement">
    <CStatement>
      <CStatementId>

      </CStatementId>
      <CStatementDate>
        <xsl:choose>
          <xsl:when test ="/urn:Document/urn:CustomerRecord/urn:Statement/urn:StmtDate!=''">
            <xsl:value-of select="/urn:Document/urn:CustomerRecord/urn:Statement/urn:StmtDate" />
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Balance[contains('|CL|FW|', concat('|', urn:Type, '|'))]/urn:Date" />
          </xsl:otherwise>
        </xsl:choose>
      </CStatementDate>
      <AccountNumber>
        <xsl:if test="/urn:Document/urn:CustomerRecord/urn:Statement/urn:AcctNumber!=''">
          <xsl:value-of select ="/urn:Document/urn:CustomerRecord/urn:Statement/urn:AcctNumber"/>
        </xsl:if>
      </AccountNumber>
      <OpeningBalance>
        <xsl:choose>
          <xsl:when test="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Balance[contains('|OP|PR|', concat('|', urn:Type, '|'))]/urn:CdtDbtInd='DR'">
            <xsl:value-of select="format-number(/urn:Document/urn:CustomerRecord/urn:Statement/urn:Balance[contains('|OP|PR|', concat('|', urn:Type, '|'))]/urn:Amount * -1, '#.00')" />
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="format-number(/urn:Document/urn:CustomerRecord/urn:Statement/urn:Balance[contains('|OP|PR|', concat('|', urn:Type, '|'))]/urn:Amount, '#.00')" />
          </xsl:otherwise>
        </xsl:choose>
      </OpeningBalance>
      <ClosingBalance>
        <xsl:choose>
          <xsl:when test="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Balance[contains('|CL|FW|', concat('|', urn:Type, '|'))]/urn:CdtDbtInd='DR'">
            <xsl:value-of select="format-number(/urn:Document/urn:CustomerRecord/urn:Statement/urn:Balance[contains('|CL|FW|', concat('|', urn:Type, '|'))]/urn:Amount * -1, '#.00')" />
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="format-number(/urn:Document/urn:CustomerRecord/urn:Statement/urn:Balance[contains('|CL|FW|', concat('|', urn:Type, '|'))]/urn:Amount, '#.00')" />
          </xsl:otherwise>
        </xsl:choose>
      </ClosingBalance>
      <xsl:apply-templates select="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry" />
    </CStatement>
  </xsl:template>

  <xsl:template match="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry">
    <StatementLine>
      <DebitOrCredit>
        <xsl:value-of select ="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry/urn:CreditOrDebit"/>
      </DebitOrCredit>
      <Amount>
        <xsl:choose>
          <xsl:when test="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry/urn:CreditOrDebit='DR'">
            <xsl:value-of select="format-number(/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry/urn:Amount * -1, '#.00')" />
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="format-number(/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry/urn:Amount, '#.00')" />
          </xsl:otherwise>
        </xsl:choose>
      </Amount>
      <CustomerName>
        <xsl:value-of select="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry/urn:EntryDtls/urn:TransactionDetails/urn:Parties/urn:Customer/urn:Name" />
        <!--NtryDtls/TransactionDetails/Parties/Dbtr/Nm-->
      </CustomerName>
      <CustomerBankAccount>
        <xsl:value-of select="/urn:Document/urn:CustomerRecord/urn:Statement/urn:Entry/urn:EntryDtls/urn:TransactionDetails/urn:Parties/urn:CustomerAcct/urn:AcctNumber" />
      </CustomerBankAccount>
      <Description>


      </Description>
    </StatementLine>
  </xsl:template>
</xsl:stylesheet>

应该有这个输出：

<?xml version="1.0" encoding="utf-8"?>
<Root> <!--should have no attribute-->
  <CStatement>
    <CStatementId>123</CStatementId>
    <CStatementDate>2013-08-16</CStatementDate>
    <AccountNumber>123456789</AccountNumber>
    <OpeningBalance>-1.00</OpeningBalance>
    <ClosingBalance>2.00</ClosingBalance>
    <CStatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>-7778.70</Amount>
      <CustomerName>Customer 1 Name</CustomerName>
      <CustomerBankAccount>12345677</CustomerBankAccount>
      <Description></Description>
    </CStatementLine>
    <StatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>5555.70</Amount>
      <CustomerName>Customer 2 Name</CustomerName>
      <CustomerBankAccount>12345678</CustomerBankAccount>
      <Description></Description>
    </StatementLine>
  </CStatement>
  <CStatement>
    <CStatementId>124</CStatementId>
    <CStatementDate>2013-08-18</CStatementDate>
    <AccountNumber>123456780</AccountNumber>
    <OpeningBalance>4.00</OpeningBalance>
    <ClosingBalance>-5.00</ClosingBalance>
    <CStatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>7777.70</Amount>
      <CustomerName>Customer 3 Name</CustomerName>
      <CustomerBankAccount>12345679</CustomerBankAccount>
      <Description></Description>
    </CStatementLine>
  </CStatement>
</Root>

我的XSLT有两个问题： 1它只获得Statement或StatementLines的第一个值：

<Root xmlns:urn="urn-sample">
  <CStatement>
    <CStatementId>123</CStatementId>
    <CStatementDate>2013-08-16</CStatementDate>
    <AccountNumber>123456789</AccountNumber>
    <OpeningBalance>1.00</OpeningBalance>
    <ClosingBalance>2.00</ClosingBalance>
    <StatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>-7778.70</Amount>
      <CustomerName>Customer 1 Name</CustomerName>
      <CustomerBankAccount>12345677</CustomerBankAccount>
      <Description />
    </StatementLine>
    <StatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>-7778.70</Amount>
      <CustomerName>Customer 1 Name</CustomerName>
      <CustomerBankAccount>12345677</CustomerBankAccount>
      <Description />
    </StatementLine>
    <StatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>-7778.70</Amount>
      <CustomerName>Customer 1 Name</CustomerName>
      <CustomerBankAccount>12345677</CustomerBankAccount>
      <Description />
    </StatementLine>
  </CStatement>
  <CStatement>
    <CStatementId>123</CStatementId>
    <CStatementDate>2013-08-16</CStatementDate>
    <AccountNumber>123456789</AccountNumber>
    <OpeningBalance>1.00</OpeningBalance>
    <ClosingBalance>2.00</ClosingBalance>
    <StatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>-7778.70</Amount>
      <CustomerName>Customer 1 Name</CustomerName>
      <CustomerBankAccount>12345677</CustomerBankAccount>
      <Description />
    </StatementLine>
    <StatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>-7778.70</Amount>
      <CustomerName>Customer 1 Name</CustomerName>
      <CustomerBankAccount>12345677</CustomerBankAccount>
      <Description />
    </StatementLine>
    <StatementLine>
      <DebitOrCredit>DR</DebitOrCredit>
      <Amount>-7778.70</Amount>
      <CustomerName>Customer 1 Name</CustomerName>
      <CustomerBankAccount>12345677</CustomerBankAccount>
      <Description />
    </StatementLine>
  </CStatement>
</Root>

2最后，我不知道如何使用变量或任何函数来存储具有此要求的Description标记的值：

• 一个。连接字符串＆＃39; CUST＆＃39; +客户/姓名+客户/地址
• 湾连接字符串＆＃39; ACCT＆＃39; + CustomerAcct / AcctName +＆gt; CustomerAcct / AcctNumber
• ℃。在AddlInfo / Info1
下连接任何值
• 等
• 连接a + b + c .... etc

我希望有人可以帮助我。谢谢大家

BTW我在XSLT 1.0上需要它

Answer 1

你的基本错误是你使用绝对路径而不是相对路径。比较这两个最小化样式表的结果：

XSLT 1.0（绝对值）

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
                xmlns:urn="urn-sample">
<xsl:strip-space elements="*" />
<xsl:output indent="yes" omit-xml-declaration="yes" />

<xsl:template match="/urn:Document">
    <Root>
        <xsl:apply-templates select="/urn:Document/urn:CustomerRecord/urn:Statement" />
    </Root>
</xsl:template>

<xsl:template match="/urn:Document/urn:CustomerRecord/urn:Statement">
    <CStatement>
        <CStatementId>
            <xsl:value-of select="/urn:Document/urn:CustomerRecord/urn:Statement/urn:StmtId" />
        </CStatementId>
    </CStatement>
</xsl:template>

</xsl:stylesheet>

XSLT 1.0（相对）

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:urn="urn-sample"
exclude-result-prefixes="urn">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:strip-space elements="*" />

<xsl:template match="/urn:Document">
    <Root>
        <xsl:apply-templates select="urn:CustomerRecord/urn:Statement" />
    </Root>
</xsl:template>

<xsl:template match="urn:Statement">
    <CStatement>
        <CStatementId>
            <xsl:value-of select="urn:StmtId" />
        </CStatementId>
    </CStatement>
</xsl:template>

</xsl:stylesheet>

在第一个例子中，指令：

<xsl:value-of select="/urn:Document/urn:CustomerRecord/urn:Statement/urn:StmtId" />

从根开始并始终获取第一个语句的Id值，无论循环当前处理哪个语句。
