【问题标题】：Flat xml to hierarchial xml with new tags带有新标签的平面 xml 到分层 xml
【发布时间】：2017-04-11 08:19:24
【问题描述】：

我有这个需要样式的 xml，但我什至无法让 for.each 正常工作：我尝试，对于每个 CONNECTIVITY_MESSAGE_LINE，如果 NAME 是 'HEADER' 然后...

我需要帮助开始...这样我至少可以得到正确的陈述，我已经阅读并阅读...

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">
  <xsl:output method="xml" indent="yes"/>
  <xsl:template match="@* | node()"> 
    <xsl:element name="SEPA_HEADER">  
        <xsl:value-of select=". = HEADER"/>
        <xsl:if test="*//NAME[text() = 'HEADER']">
          <p>x</p>          
        </xsl:if>               
        <xsl:for-each select="CONNECTIVITY_MESSAGE/MESSAGE_LINE/CONNECTIVITY_MESSAGE_LINE">
          <P>1</P>
        <xsl:choose>
          <xsl:when test="//NAME[text() = 'HEADER']">
            <P>CHOOSE</P>
          </xsl:when>
          <xsl:otherwise>
            <p>123</p>
          </xsl:otherwise>
        </xsl:choose>
        </xsl:for-each>   
      </xsl:element>
  </xsl:template>
</xsl:stylesheet>

我用的是VS2013

我讨厌的 xml：

【问题讨论】：

我现在用找到了 chils 节点的值我注意到所有的输出 xml 都在一行中......有什么想法吗？
您的 CONNECTIVITY_MESSAGE 节点中似乎有 xmlns:xsi="w3.org/2001/XMLSchema-instance" xmlns="urn:ifsworld-com:connectivity_message" ID="CONNECTIVITY_MESSAGE-6.0"导致处理问题是源 xml 中必需的那些属性吗？
我已经删除了 linie 并且知道至少我可以使用一些 xpath 语法。
@Lise 无需修改您的 XML； XSLT 可以处理任何 XML 输入。请参阅：stackoverflow.com/questions/34758492/…您的尝试还有其他问题，但这会给您一个开始。

【解决方案1】：

从您的帖子中不清楚您想要输出 XML 的内容。对于处理输入 XML 的更 XSL-y 方式，我建议如下。使用模板可以避免您对for-each 的任何需求，就像您尝试使用它一样。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"

    exclude-result-prefixes="xs"
    version="2.0"

    xmlns="urn:ifsworld-com:connectivity_message"
    xpath-default-namespace="urn:ifsworld-com:connectivity_message">
    <!-- Note the `xpath-default-namespace` line here: this is only allowed in XSLT 2.0 and newer.
        The input XLIFF file itself specifies this URI as the unprefixed namespace for the whole file.
        If we don't specify this as the XPath default namespace, we have to specify element names
        in ugly workaround syntax, such as `*[local-name() = 'MESSAGE_LINES']`. -->

    <!-- Indent for easier human readability. -->
    <xsl:output method="xml" indent="yes"/>

    <!-- Strip space so that skipped elements don't result in blank whitespace in the output. -->
    <xsl:strip-space elements="*"/>

    <!-- Start at the top -->
    <xsl:template match="/CONNECTIVITY_MESSAGE">
        <!-- Here, we just copy the element.  Change if you need something different in your output. -->
        <xsl:copy>
            <!-- I assume here that you want to also copy over all of the elemnt attributes. -->
            <xsl:copy-of select="@*"/>
            <!-- Now, just pass in all the children elements for further processing. -->
            <xsl:apply-templates/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="MESSAGE_LINES">
        <!-- From your sample code, I have no clear idea if this is what 
            you intend for the SEPA_HEADER element.  Change as appropriate. -->
        <SEPA_HEADER>
            <!-- Now pass in all children of the MESSAGE_LINES element
                (in this case, all the CONNECTIVITY_MESSAGE_LINE structures).-->
            <xsl:apply-templates/>
        </SEPA_HEADER>
    </xsl:template>

    <xsl:template match="CONNECTIVITY_MESSAGE_LINE">
        <xsl:copy>
            <!-- Your sample code had:
                    <xsl:when test="//NAME[text() = 'HEADER']">
                The // here means that this is TRUE if there is *any* 
                NAME *anywhere in the file* that has text of 'HEADER'.
                Given your sample file, this will *always* be true, no
                matter where we are.  I suspect you instead need to 
                check if _this specific CONNECTIVITY_MESSAGE_LINE_ has
                a NAME element with text of 'HEADER'. -->
            <xsl:choose>
                <!-- You can test the text value of an element by simply evaluating `.` ("this").
                    You can, but you don't need to, evaluate using `text()`. -->
                <xsl:when test="NAME[. = 'HEADER']">
                    <p>CHOOSE</p>
                </xsl:when>
                <xsl:otherwise>
                    <p>123</p>
                </xsl:otherwise>
            </xsl:choose>
            <!-- I assume here that you want to copy all the children.
                Change as appropriate for your needs. -->
            <xsl:copy-of select="*"/>
        </xsl:copy>
    </xsl:template>

    <!-- Suppress output of anything else for which we do not have a specific template defined. -->
    <xsl:template match="*"/>

</xsl:stylesheet>

这应该可以帮助您入门。看看，阅读 cmets，让我们知道您可能还有什么问题。
