Question

我有這個網站：

<a id='topnavbtn_tutorials' href='javascript:void(0);' onclick='w3_open_nav("tutorials")' title='Tutorials'>TUTORIALS <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_references' href='javascript:void(0);' onclick='w3_open_nav("references")' title='References'>REFERENCES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_examples' href='javascript:void(0);' onclick='w3_open_nav("examples")' title='Examples'>EXAMPLES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a href='/forum/default.asp'>FORUM</a></div></div> 
<div id='nav_tutorials' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div> 
<div id='nav_references' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div> 
<div id='nav_examples' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div> 
<div id='nav_translate' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div> 
<div id='nav_search' class='w3-dropnav w3-light-grey w3-card-2 w3-center'></div></div> 
<div class='w3-row w3-light-grey' id='belowtopnav'> 
<div class='w3-col w3-slim' id='leftmenu'> 
<div id='leftmenuinner'> 
<div class='w3-light-grey' id='leftmenuinnerinner'> 
<a href='javascript:void(0)' onclick='close_menu()' class='w3-closebtn w3-hide-large w3-large' style='padding:3px 12px;'>&times;</a> 
<h2 class="left"><span class="left_h2">Colors</span> Tutorial</h2> 
<a target="_top" href="default.asp">Colors HOME</a> 
<a target="_top" href="colors_names.asp">Color Names</a> 

而且我寫這個表達式：

<a .*?href=("|').*?\.asp("|').*?>.*?<\/a> 

我只需要搭配：

1.

<a href='/forum/default.asp'>FORUM</a> 

2.

<a target="_top" href="default.asp">Colors HOME</a> 

3.

<a target="_top" href="colors_names.asp">Color Names</a> 

下面是從當前正則表達式匹配項（初結果是壞的）：

1.

<a id='topnavbtn_tutorials' href='javascript:void(0);' onclick='w3_open_nav("tutorials")' title='Tutorials'>TUTORIALS <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_references' href='javascript:void(0);' onclick='w3_open_nav("references")' title='References'>REFERENCES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a id='topnavbtn_examples' href='javascript:void(0);' onclick='w3_open_nav("examples")' title='Examples'>EXAMPLES <i class='fa fa-caret-down'></i><i class='fa fa-caret-up' style='display:none'></i></a><a href='/forum/default.asp'>FORUM</a> 

2.

<a target="_top" href="default.asp">Colors HOME</a> 

3.

<a target="_top" href="colors_names.asp">Color Names</a> 

請修改我現有的正則表達式。

Answer 1

此正則表達式似乎很好地工作：

<a.*?href=["']{1}.*?\.asp["']{1}.*?>.*?<\/a>
