The <xsl:preserve-space> element is used to define the elements for which white space should be preserved.
<xsl:preserve-space>元素的作用是:定义需要保留空白行符的元素。
The <xsl:strip-space> element is used to define the elements for which white space should be removed.
<xsl:strip-space>元素的作用是:定义需要删除空白行符的元素。
Note: Preserving white space is the default setting, so using the <xsl:preserve-space> element is only necessary if the <xsl:strip-space> element is used.
注意:保留空白行符时默认的设置,因此,如果使用了<xsl:strip-space>元素,那么就必须使用<xsl:preserve-space>元素。
Note: The <xsl:preserve-space> element and the <xsl:strip-space> element are top-level elements.
注意: <xsl:preserve-space> 元素和<xsl:strip-space>元素都是顶级元素。
<xsl:preserve-space elements="list-of-element-names"/> <xsl:strip-space elements="list-of-element-names"/> |
属性 | 值 | 描述 |
---|---|---|
elements | list-of-element-names | Required. A white space separated list of element names for which white space should be preserved/removed. Note: The list can also contain "*" and "prefix:*" so that all elements or all elements from a particular namespace can be joined |
In the example below we preserve white space nodes for title and artist elements, and remove white space nodes for country, company, price, and year elements:
在下面的案例中,我们为title和artist元素保留了空白行符节点,删除了country、company、price以及year元素的空白行符节点:
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:strip-space elements="country company price year" /> <xsl:preserve-space elements="title artist" /> <xsl:template match="/"> <html> <body> <xsl:for-each select="catalog/cd"> <p> <xsl:value-of select="title" /><br /> <xsl:value-of select="artist" /><br /> <xsl:value-of select="country" /><br /> <xsl:value-of select="company" /><br /> <xsl:value-of select="price" /><br /> <xsl:value-of select="year" /> </p> </xsl:for-each> </body> </html> </xsl:template> </xsl:stylesheet> |
