Question

我是第一次发帖，所以如果我做错了，请接受我的道歉。。基本上我正在尝试的是使用XSLT从XML创建XML。我尝试在线参考示例但我找不到类似的东西。我正在尝试的可以分为3个主要步骤：

为3种不同的方法设置模板。创建，更新和清除。创建和更新需要一些逻辑来转换XML 而Purge方法将解析XML。
将部分XML从PromoMessage标记解析为结束标记以进行分发。
在XML中实际输出的字段包含我引用的标记的值。

以下是源XML的两个示例：

Source 1是最复杂的源，它需要逻辑来选择插页式类别并提升程序类型，创建的方法应该参考使用这个逻辑。更新方法的工作方式相同：

<?xml version="1.0" ?>
<PromoMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Header origin="IBMSV6" method="create" timestamp="2013-08-06T06:32:17Z" />
<Body>
<CreatePromo providerId="NJR" promoID="245686_NJ01858S ">
<Distribution>
<RightsWindow start="2013-07-31T14:00:00Z" end="2013-08-31T13:59:59Z" />
<Destinations>
<Destination platform="WCMS" site="EPG" visible="true">
<DisplayWindow start="2013-07-31T14:00:00Z" end="2013-08-31T13:59:59Z" />
</Destination>
</Destinations>
</Distribution>
<Interstitial category= "episodic" multi_prog="false" name="Promo Alpha" parentalRating ="PG"  >
<PromotedProgramme type ="MovieOrEvent" seq_number ="1" > //promoted prog non-series
<TitleId>000000218564</TitleId>
<ExternalProgId>785432</ExternalProgId>
<TitleBroadcastRef>078654</TitleBroadcastRef>
<TitleName>Men In Black</TitleName>
</PromotedProgramme>
<PromotedProgramme type ="MoviefssOrEvent" seq_number ="2"> <!--promoted slot non-series-->
<SlotId>675342</SlotId>
<SlotName>Late Movie</SlotName>
<TitleId>000000218576</TitleId>
<ExternalProgId>785632</ExternalProgId>
<TitleBroadcastRef>078123</TitleBroadcastRef>
<TitleName>Die Hard</TitleName>
<EPGTitleName>Die Hard</EPGTitleName>
</PromotedProgramme>
<PromotedProgramme type ="Series" seq_number ="3"> <!--promoted prog series-->
<TitleId>000000218321</TitleId>
<ExternalProgId>785122</ExternalProgId>
<TitleBroadcastRef>075432</TitleBroadcastRef>
<TitleName> Friends S5 Ep5</TitleName>
<EpisodeNo>10</EpisodeNo>
<SeasonId>10645346</SeasonId>
<SeasonName>Friends</SeasonName>
<SeasonNo>5</SeasonNo>
<SeasonYear>5</SeasonYear>
<ShowId>10987532</ShowId>
<ShowName>Friends</ShowName>
<EPGTitleName>Friends</EPGTitleName>
</PromotedProgramme>
<PromotedProgramme type ="Slot" seq_number ="4"> <!--promoted slot - no prog or title assigned to slot-->
<SlotId>675347</SlotId>
<SlotName>Late Movie</SlotName>
</PromotedProgramme>
<PromotedProgramme type ="ExtChannel" seq_number ="5"> <!--promoted prog from ext.channel-->
<PromotedBroadcastRef>675347</PromotedBroadcastRef >
</PromotedProgramme>
</Interstitial>
<Media>
<Source>playout</Source>
<Identifier>NJ01858S </Identifier>
<AspectRatio>16X9 </AspectRatio>
</Media>
</CreatePromo>
</Body>
</PromoMessage>

源2是一个清除请求，需要根据以下方法进行解析：

- <PromoMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Header origin="IBMSV6" method="purge" timestamp="2013-08-06T06:34:07Z" /> 
- <Body>
- <PurgePromo providerId="NJR" promoID="245685_NJ01857S">
- <Distribution>
- <Destinations>
  <Destination platform="WCMS" site="EPG" /> 
  </Destinations>
  </Distribution>
  </PurgePromo>
  </Body>
  </PromoMessage>

这是我目前的XSLT：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" >

如果有人能指出我正确的方向，我当然会很感激，谢谢。

Answer 1

我可以回答你关于第一步的问题，因为这是我认为的唯一部分（？）我明白了：

创建和更新需要一些逻辑来转换XML Purge方法将解析XML。

您的XSLT需要具有以下基本结构：

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

<xsl:template match="/PromoMessage[Header/@method='create' or Header/@method='update']">
    <!-- logic to process "create/update" message types  -->
</xsl:template>

<xsl:template match="/PromoMessage[Header/@method='purge']">  
    <!-- logic to process "purge" message type  -->
</xsl:template>

</xsl:stylesheet>

我不太清楚你的意思：

Purge方法将解析XML。

如果通过＆＃34;解析＆＃34;你的意思是＆＃34;传递＆＃34; - 即按，然后逻辑处理＆＃34;清除＆＃34;消息类型可以非常简单：

<xsl:template match="/PromoMessage[Header/@method='purge']">  
    <xsl:copy-of select="."/>
</xsl:template>

我建议您针对任何特定问题发布单独的问题，并处理＆＃34;创建/更新＆＃34;消息类型。
