上面的例子都是现实操作中广泛（流行）用法，大家可能感觉到外置式有些复杂，其实不然，你只要把它做成一个函数或者对象就相当容易了。</td></tr></table><table align=center width=620><tr><td class=a14>
关键问题在于，变量的替换，若使用上面的方法，有些不妥，因为默写模板页面不一定是适合的那些变量，如果你把所有的变量都放在foreach里面，那么势必对于程序运行资源造成极大浪费，而且得不偿失，影响效率。这样做成一个函数或者对象，对会有不通用的问题。</td></tr></table><table align=center width=620><tr><td class=a14>
所以建立一个灵活的分析方法，对于模板HTML处理提供良好的快捷的运作模式。</td></tr></table><table align=center width=620><tr><td class=a14>
这个时候我们就要利用Perl强大的语法分析，来做一个自己的HTML语言分析语句了。这个语句看似简单缺令人头疼。</td></tr></table><table align=center width=620><tr><td class=a14>
我们现在以“*”符号作为模板中的变量（类似于Perl 中的$），这样有助于辨析。那么我想要把所有以“＊”开头的变量，自动变换成程序内的对应变量，例如：要把*abc成为内部的$abc。一般情况我们需要逐个设置，这样大大浪费了时间，我们现在需要做一个通用的方法，无论什么的量都自动转换。这个语法很简单：</td></tr></table><table align=center width=620><tr><td class=a14>
$_ =~ /\*(\w+)/;</td></tr></table><table align=center width=620><tr><td class=a14>
看似简单的一局话，却有很大的作用，这句就是把以*开头的字符的名找出来，但是有趣的是，你不需要进行太复杂的，只要遇到空格或者其它非标准字符，就会自动排除。</td></tr></table><table align=center width=620><tr><td class=a14>
现在我们要把找到的字符名（即HTML的自定义变量）发给一个临时变量中（该步骤可以不做）：$tmp = $1 ;</td></tr></table><table align=center width=620><tr><td class=a14>
现在要做的就是把这个*abc换成量$abc的值：</td></tr></table><table align=center width=620><tr><td class=a14>
$_ =~ s/\*$tmp/$Html{"$tmp"}/g</td></tr></table><table align=center width=620><tr><td class=a14>
这里的$Html是散列变量(HASH)，为了方便和容易理解，我在这里采用HASH，这样对应的$Html{‘abc’}就被提出来，换掉*abc了。</td></tr></table><table align=center width=620><tr><td class=a14>
下面就是我做的模板套用函数与例子。</td></tr></table><table align=center width=620><tr><td class=a14>
