根元素由出版社(Publisher),书的线索(Thread),书(Book)组成。
在xsl求每本书的出版社名字的一段：
<xsl:template match="Book">
   <xsl:apply-templates select="Title"/>
   <xsl:variable name="isbn" select="@ISBN"/>
   <xsl:element name="DIV">
      <xsl:attribute name="style">font-family:Verdana;font-size:10pt;color:black;font-weight:bolder</xsl:attribute>
      <xsl:value-of select="/Catalog/Publisher[contains($isbn,@isbn)]/CorporateName"/>//这个地方怎么有两个属性isbn，到底属于谁的，难道是模板匹配的当前属性ISBN(Book里的)优先考虑，@isbn匹配其指定的路径吗(Publisher里的)？属性名不同还好说，如果是同名的怎么办啊，如果是用到了三个这样的属性，又该如何匹配？
   </xsl:element>
   <xsl:variable name="by" select="@authors"/>
   <xsl:call-template name="fetch-authors">
      <xsl:with-param name="authors" select="/Catalog/Publisher/Author[contains($by,@authorCiteID)]"/>
   </xsl:call-template>
   .......
另外一个问题和xpath有关：
<xsl:apply-templates select="*[name() != 'Title']"/>
这个模板从效果上看是匹配所有当前上下文节点的名字不为Title的子节点，可按照xpath的写法，我觉得前面应该加上child，才能表明是上子节点里去找，即：child::*[name()]!='Title',不知对不对，要不怎么知道到哪里去找呢？难道默认是到子节点里去找？我试了也可以，有点纳闷。

是不是嫌我们的问题太简单了，没有人回答啊。

<xsl:value-of select="/Catalog/Publisher[contains($isbn,@isbn)]/CorporateName"/>中的$isbn是指变量isbn-><xsl:variable name="isbn" select="@ISBN"/> @isbn是指属性。
<xsl:template match="Book">
   <xsl:apply-templates select="Title"/>
这里的apply-templates是指在book下面的子节点来匹配这些模版的，所以就不用child了。

睡了几天头有些昏，回答的不好的话，请原谅。哈哈
