Definition and Usage
¶¨ÒåºÍÓ÷¨
The <xsl:preserve-space> element is used to define the elements for which white space should be preserved.
<xsl:preserve-space>ÔªËØµÄ×÷ÓÃÊÇ£º¶¨ÒåÐèÒª±£Áô¿Õ°×ÐзûµÄÔªËØ¡£
The <xsl:strip-space> element is used to define the elements for which white space should be removed.
<xsl:strip-space>ÔªËØµÄ×÷ÓÃÊÇ£º¶¨ÒåÐèҪɾ³ý¿Õ°×ÐзûµÄÔªËØ¡£
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.
