很抱歉，如果这看起来很荒谬我真的在这里尝试但是我没有抓住我所在的xml课程。请看一看并指出我正确的方向，或者如果你至少可以把我带出深渊
这是xml部分

<title>Visual Memory</title>
<link>vm.htm</link>
<description>BOULDER, Colorado - The ability to retain memory about the
details of a natural scene is unaffected by the distraction of another
activity and this information is retained in "working memory" according
to researchers at the University of Colorado School of Medicine. These
results reinforce the notion that humans maintain useful information about
previous fixations in long-term working memory rather than the
limited capacity of visual short-term memory (VSTM).

<description>CAPE CANAVERAL, Florida - The fastest spacecraft ever launched
began the first full day of its 2-billion mile journey to Neptune, where it
will study the gas giant and provide close-up images of its rings. The Neptune 5
spacecraft blasted off aboard an Atlas V rocket Sunday evening in a spectacular
start to the $900 million mission. The spacecraft can reach 38,000 mph, taking 6
years to reach Neptune and the outer reaches of the Solar System.

<title>Whale numbers in decline</title>
<link>whales.htm</link>
<description>ANCHORAGE, Alaska - A survey of beluga whales in Cook Inlet finds
that their numbers remain stagnant and could be declining despite efforts to get
the white whale population to rebound. Biologists with the NOAA conducted an aerial
survey southwest of Anchorage early last summer to count the belugas. An analysis
of the survey data indicates there were an estimated 324 beluga whales in Cook Inlet
in 2007, down from 376 the year before.

<description>LOS ANGELES, California - A NASA satellite studying the Earth's Van
Allen Belt has stopped operating after three years, the space agency announced
over the weekend. The satellite, launched in 2004, successfully completed its
two-year primary mission, according to a NASA news release. It made observations
until last month when engineers discovered that its power supply had failed.

我得到的输出正是“日期，描述，RSS新闻源和正文部分中的项目所说的内容！请告诉我我做错了什么。
答案 0 :(得分：2)
你有几个错误。基本错误是您错误地唤起了模板。 例如：
//you need to indicate path to the node
<xsl:apply-templates select="channel/description"/>
我已经解决了一些问题，试试这个：
