вывод в следующем виде:

2011-11-20 20:00:00,(Sun) R Nadal v M Fish (TV), 1.20,4.40,1.30,6.00
2011-11-21 14:00:00,(Mon) A Murray v D Ferrer (TV), 1.13,5.40,1.20,8.20
2011-11-21 20:00:00,(Mon) N Djokovic v T Berdych (TV), 1.42,2.72,1.60,3.40

Таким образом, мой XSLT-скрипт не способен видеть события.Как мне изменить XSLT, чтобы в этом случае учесть?

Answer 1

Похоже, это довольно далеко зашло бы:

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

  <xsl:template match="/">
    <xsl:apply-templates select="
      root/SPORT[@NAME='Tennis']/EVENT//MARKET[@NAME='Match Betting']
    " />
  </xsl:template>

  <xsl:template match="MARKET[@NAME='Match Betting']">
    <xsl:value-of select="../@DATE"/><xsl:text>,</xsl:text>
    <xsl:value-of select="../@NAME"/><xsl:text>, </xsl:text>
    <xsl:apply-templates select="SELECTION[1]/OUTCOME/ODDS[@POLARITY='BACK']" /><xsl:text>,</xsl:text>
    <xsl:apply-templates select="SELECTION[2]/OUTCOME/ODDS[@POLARITY='BACK']" /><xsl:text>,</xsl:text>
    <xsl:apply-templates select="SELECTION[1]/OUTCOME/ODDS[@POLARITY='LAY']" /><xsl:text>,</xsl:text>
    <xsl:apply-templates select="SELECTION[2]/OUTCOME/ODDS[@POLARITY='LAY']" /><xsl:text>&#10;</xsl:text>
  </xsl:template>

  <xsl:template match="ODDS[PRICE/@VALUE]"><!-- odds with a price value -->
    <xsl:value-of select="PRICE/@VALUE"/>
  </xsl:template>

  <xsl:template match="ODDS"><!-- odds without a price value -->
    <xsl:text>0.00</xsl:text>
  </xsl:template>
</xsl:stylesheet>

Для обоих примеров XML в вашем вопросе это дает следующий вывод:

2011-11-20 14:00:00,(Sun) R Federer v JW Tsonga (TV), 1.23,3.65,1.31,5.10
2011-11-20 20:00:00,(Sun) R Nadal v M Fish (TV), 1.20,4.40,1.30,6.00

Если вам все равно, есть ли <SUBEVENT1> / <SUBEVENT2> элементы или нет, просто игнорируйте их.

Кажется, вам интересны элементы <MARKET NAME="Match Betting">, поэтому выберите их напрямую:

root/SPORT[@NAME='Tennis']/EVENT//MARKET[@NAME='Match Betting']

Второй шаблон соответствует им и создает строку вывода.Третий и четвертый шаблоны обрабатывают оба типа элементов <ODDS>.

Вы можете видеть, что XSLT может быть коротким и эффективным, если все сделано правильно.Для начала стоит забыть о <xsl:for-each>.Звучит полезно, но это не так.

Взгляните на <xsl:apply-templates>.Он работает как для каждого, но гораздо гибче.

Answer 2

Не зная точно, чего вы пытаетесь достичь, и без правильно сформированного вклада, я думаю, что вы пытаетесь сделать ...

Ниже приведена измененная версия вашей таблицы стилей. Основная часть этого неизменна; в основном я изменил match и один for-each.

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

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

  <xsl:template match="SUBEVENT2|SUBEVENT1[not(SUBEVENT2)]|SUBEVENT[not(SUBEVENT1)]">
    <xsl:for-each select=".">
      <xsl:sort select="./MARKET/@DATE"/>

        <xsl:value-of select="','"/>
        <xsl:value-of select="./@NAME"/>
        <xsl:value-of select="','"/>
        <xsl:value-of select="' '"/>
        <xsl:choose>
          <xsl:when test="./MARKET[@NAME='Match Betting']/SELECTION[1]/OUTCOME/ODDS[@POLARITY='BACK']/PRICE/@VALUE[1]">
            <xsl:value-of select="./MARKET[@NAME='Match Betting']/SELECTION[1]/OUTCOME/ODDS[@POLARITY='BACK']/PRICE/@VALUE[1]"/>
          </xsl:when>
          <xsl:otherwise>

        <xsl:choose>
          <xsl:when test="./MARKET[@NAME='Match Betting']/SELECTION[2]/OUTCOME/ODDS[@POLARITY='BACK']/PRICE/@VALUE[1]">

          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="'0.00'"/>
          </xsl:otherwise>
        </xsl:choose>
        <xsl:value-of select="','"/>
        <xsl:choose>
          <xsl:when test="./MARKET[@NAME='Match Betting']/SELECTION[2]/OUTCOME/ODDS[@POLARITY='LAY']/PRICE/@VALUE[1]">
            <xsl:value-of select="./MARKET[@NAME='Match Betting']/SELECTION[2]/OUTCOME/ODDS[@POLARITY='LAY']/PRICE/@VALUE[1]"/>
          </xsl:when>

        <xsl:value-of select="'&#10;'"/>
      </xsl:if>
    </xsl:for-each>
  </xsl:template>

</xsl:stylesheet>
