获取冒号后的值 - 键 [英] Get the value after the colon - keys

问题描述

我对此几乎有相同的问题:在每个最后一个冒号后获取值.就我而言，我需要对 :A: 和 :B: 的每次出现进行迭代，:B: 是 :A: 的子项.在我的代码中，我使用了一个我不太熟悉的调用模板.但是，我需要探索 xslt 中的其他功能/元素.

I have almost the same issue for this one: Get value after each last colon. In my case, I need to iterate for every occurrence of :A: and :B:, :B: is a child of :A:. In my code, I am using a call-template which is I'm not very familiar with. But, I need to explore the other functionalities/elements in xslt.

这是我的示例测试文件:

Here is my sample test file:

<Record>
:A:This is sample only 1
:B:This is sample only 2
:B:This is sample only 3
:A:This is sample only 4
:B:This is sample only 5
</Record>

预期输出:

<Record>
  <Detail>
    <FieldA>This is sample only 1</FieldA>
    <Trans>
      <Group>
        <FieldB>This is sample only 2</FieldB>
      </Group>
      <Group>
        <FieldB>This is sample only 3</FieldB>
      </Group>
    </Trans>
  </Detail>
  <Detail>
    <FieldA>This is sample only 4</FieldA>
    <Trans>
      <Group>
        <FieldB>This is sample only 5</FieldB>
      </Group>
    </Trans>
  </Detail>
<Record>

对于每次出现:A:，我需要创建一个 记录，然后对于每个:B: 将创建一个 记录.这是我的 XSLT 代码，

For every occurrence of :A:, I need to create a <Detail> record, then for each :B: will create a <Group> record. And here is my XSLT code,

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

                            <FieldB>
                                <xsl:value-of select="$FieldB"/>
                            </FieldB>

我的 xslt 代码不起作用.如果我在代码中遗漏了什么，任何人都可以帮助我.非常感谢您的反馈.

My xslt code is not working. Can anyone help me if what I missed in my code. Your feedback is highly appreciated.

谢谢！

推荐答案

我建议采用完全不同的方法:首先将字符串转换为单个元素，这样您就可以:

I would suggest a radically different approach: first convert the string to individual elements, so that you have:

<FieldA>This is sample only 1</FieldA>
<FieldB>This is sample only 2</FieldB>
<FieldB>This is sample only 3</FieldB>
<FieldA>This is sample only 4</FieldA>
<FieldB>This is sample only 5</FieldB>

在一个变量中.

然后将变量中的元素分组并按照您想要的方式输出:

Then group the elements in the variable and output them the way you want them:

xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

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

<xsl:template match="Record">
    <!-- convert strings to elements -->
    <xsl:variable name="temp" as="element()*">

            <xsl:matching-substring>
                <xsl:element name="Field{regex-group(1)}">
                    <xsl:value-of select="regex-group(2)" />

        </xsl:analyze-string>

        <!-- group elements -->

                <xsl:copy-of select="current-group()[1]" />
                <Trans>
                    <xsl:for-each select="current-group()[position() ge 2]">
                        <Group>
                            <xsl:copy-of select="." />
                        </Group>
                    </xsl:for-each>
                </Trans>
            </Detail>
        </xsl:for-each-group>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>
