问题是，我有以XML格式存在的数据，但是，关键的数据片段不是在单独的节点中提供的。例如一件物品的大小，颜色，设备。虽然我通常会提供我尝试过的东西，但我甚至不知道从哪里开始。我已经找到了很多关于如何检查是否找到一个值的例子，但是没有找到如何获取匹配的值，然后在元素中返回它的例子。我只能使用XSLT1.0

这是一个关键的部分，我需要帮助，但在这篇文章中，我包括完整的样本数据和我当前的XSL模板。

<partDescription>Black 10" Handlebar</partDescription>

复制
                        <!-- Logic to Figure out Attribute Data from Names, Descriptions -->
                        <!-- If <partDescription> contains Black, Flat Back, Chrome element finish shoud return the value that is found -->

                        <xsl:if test="finishIsFound">
                            <xsl:element name="finish">
                                <xsl:value-of select="$finishFoundFromDescription"/>
                            </xsl:element>
                        </xsl:if>

                        <!-- If <partDescription> contains a number, grab that number and set as value e.g. 8,14,16-->
                        <xsl:if test="sizeIsFound">
                            <xsl:element name="size">
                                <xsl:value-of select="$sizeFoundFromDescription"/>
                            </xsl:element>
                        </xsl:if>

下面是当前数据的示例

然后，我有了我当前的XSL模板。

这真是一团糟。

这很混乱，因为XSLT是为处理结构化数据而设计的，但是您的数据提供者选择不利用XML提供的结构。这里所需的处理类型将由regex更好地处理--然而，regex支持只在XSLT2.0中引入。

尽管如此，让我们看看能做些什么：

第一项任务是：

如果<partDescription>包含黑色、扁平背，则contains应返回找到的值

相对容易:假设可能的完成选项是相互排斥的，您可以这样做：

代码语言：javascript
复制
<xsl:choose>
    <xsl:when test="contains(partDescription, 'Black')">
        <finish>Black</finish>
    </xsl:when>
    <xsl:when test="contains(partDescription, 'Flat Back')">
        <finish>Flat Back</finish>
    </xsl:when>
    <xsl:when test="contains(partDescription, 'Chrome')">
        <finish>Chrome</finish>
    </xsl:when>
</xsl:choose>

请注意，这还假定一个选项不包含在另一个选项中。如果不是这种情况，请确保在包含选项之前对包含选项进行测试。

现在关于尺寸，你说：

如果<partDescription>包含一个数字，则获取该数字

从字面上看，你可以：

代码语言：javascript
复制
<xsl:variable name="size" select="translate(partDescription, translate(partDescription, '0123456789', ''), '')" />
<xsl:if test="$size">
    <size>
        <xsl:value-of select="$size"/>
    </size>
</xsl:if>

然而，这有两个缺陷：

  1. 它移除单元(如果大小不是整数，也移除十进制分隔符)；
  2. 将将包含在partDescription中的所有数字连接在一起，即使它们不是同一个数字的一部分。

一个更好(尽管还不完美)的解决方案将用空格字符标记描述，并寻找一个以数字开头的令牌。幸运的是，libxslt处理器支持EXSLT str:tokenize()扩展函数，因此您可以：

代码语言：javascript
复制
<xsl:variable name="size" select="str:tokenize(partDescription, ' ')[starts-with(translate(., '123456789', '000000000'), '0')]" />
<xsl:if test="$size">
    <size>
        <xsl:value-of select="$size"/>
    </size>
</xsl:if>

但是，如果描述包含多个以数字开头的单词，并且大小不是其中的第一个，这仍然会失败。

以下是这两项建议的最小实现：

XSLT1.0+ EXSLT

代码语言：javascript
复制
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:str="http://exslt.org/strings"
extension-element-prefixes="str">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/root">
    <items>
        <xsl:for-each select="part[supplierNumber/text() and partStatusDescription != 'DISCONTINUED']">
            <item>
                <xsl:copy-of select="partNumber"/>
                <!-- finish -->
                <xsl:choose>
                    <xsl:when test="contains(partDescription, 'Black')">
                        <finish>Black</finish>
                    </xsl:when>
                    <xsl:when test="contains(partDescription, 'Flat Back')">
                        <finish>Flat Back</finish>
                    </xsl:when>
                    <xsl:when test="contains(partDescription, 'Chrome')">
                        <finish>Chrome</finish>
                    </xsl:when>
                </xsl:choose>
                <!-- size -->
                <xsl:variable name="size" select="str:tokenize(partDescription, ' ')[starts-with(translate(., '23456789', '1'), '1')]" />
                <xsl:if test="$size">
                    <size>
                        <xsl:value-of select="$size"/>
                    </size>
                </xsl:if>
            </item>
        </xsl:for-each>
    </items>        
</xsl:template>

</xsl:stylesheet>

当应用于输入示例时，这将返回：

结果

代码语言：javascript
复制
<?xml version="1.0" encoding="UTF-8"?>
<items>
  <item>
    <partNumber>06012660</partNumber>
    <finish>Black</finish>
    <size>10"</size>
  </item>
  <item>
    <partNumber>06012663</partNumber>

  </item>
  <item>
    <partNumber>06013461</partNumber>
    <finish>Black</finish>
    <size>12"</size>
  </item>
  <item>
    <partNumber>06013462</partNumber>
    <finish>Black</finish>
    <size>14"</size>
  </item>
  <item>
    <partNumber>06013463</partNumber>
    <finish>Black</finish>
    <size>16"</size>
  </item>
  <item>
    <partNumber>06012662</partNumber>
    <finish>Black</finish>
    <size>12"</size>
  </item>
  <item>
    <partNumber>06012661</partNumber>
    <finish>Chrome</finish>
    <size>12"</size>
  </item>
  <item>
    <partNumber>06012659</partNumber>
    <finish>Chrome</finish>
    <size>10"</size>
  </item>
  <item>
    <partNumber>06012664</partNumber>
    <finish>Black</finish>
    <size>14"</size>
  </item>
  <item>
    <partNumber>06010612</partNumber>
  </item>
  <item>
    <partNumber>06011482</partNumber>
    <finish>Black</finish>
  </item>
</items>

添加：

在纯XSLT1.0中，使用一个递归命名模板而不是扩展函数来实现同样的功能：

XSLT1.0

代码语言：javascript

<xsl:stylesheet version="1.0"

    <items>
        <xsl:for-each select="part[supplierNumber/text() and partStatusDescription != 'DISCONTINUED']">
            <item>
                <xsl:copy-of select="partNumber"/>
                <!-- finish -->
                <xsl:choose>
                    <xsl:when test="contains(partDescription, 'Black')">
                        <finish>Black</finish>
                    </xsl:when>
                    <xsl:when test="contains(partDescription, 'Flat Back')">
                        <finish>Flat Back</finish>
                    </xsl:when>
                    <xsl:when test="contains(partDescription, 'Chrome')">
                        <finish>Chrome</finish>
                    </xsl:when>
                </xsl:choose>
                <!-- size -->
                <xsl:call-template name="find-size">
                    <xsl:with-param name="text" select="partDescription"/>
                </xsl:call-template>
            </item>
        </xsl:for-each>
    </items>        
</xsl:template>

<xsl:template name="find-size">
    <xsl:param name="text"/>
    <xsl:param name="delimiter" select="' '"/>
    <xsl:variable name="token" select="substring-before(concat($text, $delimiter), $delimiter)" />
    <xsl:choose>
        <xsl:when test="starts-with(translate($token, '123456789', '000000000'), '0')">
            <size>
                <xsl:value-of select="$token"/>
            </size>
        </xsl:when>
        <xsl:when test="contains($text, $delimiter)">
            <!-- recursive call -->
            <xsl:call-template name="find-size">
                <xsl:with-param name="text" select="substring-after($text, $delimiter)"/>
            </xsl:call-template>
