因此,我尝试使用XSLT从两个不同的XML文件中提取结果,以显示“餐厅评论”。我在allRestaurants.xml中有餐厅的详细信息,并在allReviews.xml中拥有这些餐厅的所有评论。我目前在每家餐厅都存放了一个标签,评论也与特定餐厅相关联,因此请携带相同的标签。我需要建立一个页面,其中ID为1的餐厅和下方的餐厅显示该餐厅的评论。评论与下面完全相同的1存储。请帮忙。
allRestaurants.xml
<restaurants>
<restaurant>
<restaurant_id>1</restaurant_id>
<name>The Jackaroo</name>
<street_address>107-109 Darlinghurst Road</street_address>
<postcode>2011</postcode>
<city>Sydney</city>
<state>NSW</state>
<country>Australia</country>

</restaurant>
<restaurant>
<restaurant_id>2</restaurant_id>
<name>Four Seasons restaurant Sydney</name>
<street_address>199 George Street</street_address>
<postcode>2000</postcode>
<city>Sydney</city>
<state>NSW</state>
<country>Australia</country>
<email>info@sydneyfourseasons.com.au</email>
<telephone>92503100</telephone>

</restaurant>
</restaurants>
allReviews.xml
<reviews>
<review id="1">
<restaurant_id>1</restaurant_id>
<author_id>1</author_id>
<headline>Clean Bare-Bones Hostel</headline>
<details>
Example text here
</details>
<rating>3</rating>
<date>1388782853</date>
</review>
<review id="2">
<restaurant_id>1</restaurant_id>
<author_id>3</author_id>
<headline>Wouldn't Recommend</headline>
<details>
Example text here
</details>
<rating>2</rating>
<date>1368748800</date>
</review>
<review id="3">
<restaurant_id>2</restaurant_id>
<author_id>2</author_id>
<headline>Overall I Enjoyed</headline>
<details>
Example text here
</details>
<rating>4</rating>
<date>1378788850</date>
</review>
</reviews>
我认为可能会将它们合并到一个XML文件中,这样就可以了,但即便如此,我也不确定从哪里开始:
oneHotel.xml
<?xml-stylesheet type="text/xsl" href="oneHotel.xsl"?>
<list>
<entry name="allHotels.xml" />
<entry name="reviews.xml" />
</list>
就我在XSLT文档中所做的而言,这是一个巨大的空白。我甚至不知道从哪里开始:
oneHotel.xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:copy-of name="restaurant" select="document('allRestaurants.xml')
/restaurants/restaurant[restaurant_id=1]"/>
<xsl:copy-of name="reviews" select="document('allReviews.xml')
/reviews/review[restaurant_id=1]"/>
<xsl:template match="/">
<xsl:choose>
<xsl:when test="document('allRestaurants.xml')
/restaurants/restaurant[restaurant_id=1]"/>
<h2><xsl:value-of select="name"/></h2>
</xsl:choose>
<h2><xsl:value-of select="$restaurant/name"/></h2>
</xsl:template>
</xsl:stylesheet>
答案 0 :(得分:1)
以此为出发点:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" encoding="UTF-8"/>
<xsl:param name="path-to-reviews" select="'allReviews.xml'"/>
<xsl:key name="review-by-restaurant-id" match="review" use="restaurant_id" />
<xsl:template match="/restaurants">
<html>
<body>
<h1>Restaurant Reviews</h1>
<xsl:apply-templates select="restaurant"/>
</body>
</html>
</xsl:template>
<xsl:template match="restaurant">
<h2>
<xsl:value-of select="name"/>
</h2>
<xsl:variable name="id" select="restaurant_id" />
<!-- switch context to lookup document in order to use key -->
<xsl:for-each select="document($path-to-reviews)">
<xsl:for-each select="key('review-by-restaurant-id', $id)">
<h3>
<xsl:value-of select="headline"/>
</h3>
<p>
<xsl:value-of select="details"/>
</p>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
这假设您指示XSLT处理器处理allRestaurants.xml
文档并将路径作为参数传递给allReviews.xml
文档。
您没有告诉我们您希望最终结果如何,所以我只是编写了一个非常基本的页面。
