无法在BPEL中使用XSLT选择正确的元素

标签： xml xslt bpel

我有两个变量。一个是输入，第二个是DB。在for循环中，我尝试将INPUT / numberVPN与DB / userid匹配（它们的排序方式不同，但输入中的所有数字都存在于DB变量中）。

现在一旦找到它，我希望将当前的DB / OLD_PID映射到Input / profileCode，而不是第一个。我总是得到第一，第二，......

INPUT变量（删除不需要/分类的数据）：

BPEL的XSLT代码：

<xsl:template match="/">
<ns6:VPNProvisioning>
  <VPNScenarioCollection>
    <VPNScenario>
      <profileCodeCollection>
        <xsl:for-each select="$esinfo4vpnterminate_OutputVariable.fget_esinfo4vpnterminateOutputCollection/db:fget_esinfo4vpnterminateOutputCollection/db:fget_esinfo4vpnterminateOutput">
          <xsl:if test='concat("00999",substring-before(substring(db:USERID,2.0),"/"),substring-after(db:USERID,"/")) = /ns1:ORDCOMPLETE/ns1:VPNProvisioning/VPNScenario/numberVPNCollection/numberVPN'>
            <profileCode>
              <xsl:value-of select="db:OLD_PID"/>
            </profileCode>

所以我的目标是：

对于输入变量中的每个数字，在db变量中找到相同的内容（忽略不同的格式，正确解析它）。然后，从找到匹配的节点，取old_pid并在输入变量中输入配置文件代码。

答案 0 :(得分：0)

我不了解BPEL，但您的目标可以或多或少地直接转换为xslt，简化：

    输入中的每个数字
  • ：
  • 在db-variable中找到相同的内容并使用old_pid：

对于一个工作示例，我不得不删除一些名称空间并假设INPUT是输入到xslt而不是变量，但这是一个起点。我将INPUT保存为单独的文件，并运行以下xslt：

<?xml version="1.0" encoding="UTF-8"?>

我必须使用node-set extension function才能在select中使用变量。

答案 1 :(得分：0)

我不得不使用节点名称，而是使用'。'选择for循环中的当前值。解决方案是：

<xsl:for-each select="/ns1:ORDCOMPLETE/ns1:VPNProvisioning/VPNScenario/numberVPNCollection/numberVPN">
          <xsl:variable name="foo" select="."/>
          <xsl:variable name="dbout"
                        select="$esinfo4vpnterminate_OutputVariable.fget_esinfo4vpnterminateOutputCollection/db:fget_esinfo4vpnterminateOutputCollection/db:fget_esinfo4vpnterminateOutput"/>
          <xsl:for-each select="$dbout">
            <xsl:if test="concat('00999', substring-before(substring(./db:USERID, 2.0), '/'), substring-after(./db:USERID, '/')) = $foo">
              <profileCode>
                <xsl:value-of select="./db:OLD_PID"/>
              </profileCode>
            </xsl:if>
          </xsl:for-each>
