如何从AHK的HTML代码中检索一些信息? [英] How do I retrieve some information from HTML code in AHK?
问题描述
我想从HTML代码中检索一些信息.让我们考虑以下内容:
I'd like to retrieve some information from HTML code. Let's consider the following:
<ul class="article-additional-info">
<li><strong>Issue Year:</strong> 2011</li>
<li><strong>Issue No:</strong> 1 (200)</li>
<li><strong>Page Range:</strong> 65-80</li>
<li><strong>Page Count:</strong> 15</li>
<li><strong>Language:</strong> Polish</li>
</ul>
我可以使用document.getElementsByClassName("article-additional-info")[0].innerText从article-additional-info类中获取所有信息.
I can get all the information from article-additional-info class by using document.getElementsByClassName("article-additional-info")[0].innerText.
但是我如何从此类中检索单个信息，例如2011(来自<strong>Issue Year:</strong> 2011<)呢?
我想避免使用RegEx.
But how do I retrieve individual information from this class like 2011 (from <strong>Issue Year:</strong> 2011<)?
I'd like to avoid using RegEx.
基于答案，我对代码进行了一些修改.但是，我无法摆脱一个要素:Language:.这是代码:
Based on the answer, I slightly modified the code. However, I cannot get rid of one element: Language:. Here's the code:
html =
(
<body>
<ul class="article-additional-info">
<li><strong>Issue Year:</strong> 2011</li>
<li><strong>Issue No:</strong> 1 (200)</li>
<li><strong>Page Range:</strong> 65-80</li>
<li><strong>Page Count:</strong> 15</li>
<li><strong>Language:</strong> Polish</li>
</ul>
</body>
)
document := ComObjCreate("HTMLfile")
document.write(html)
test := ["Issue Year:", "Issue No:", "Page Range:", "Page Count:"]
try While (x := document.getElementsByTagName("ul")[A_Index-1])
{
if (x.className = "article-additional-info")
{
count++
yclass%count% := x.innerHTML
}
}
loop, %count%
{
html := yclass%A_Index%
document.Close
document := ComObjCreate("HTMLfile")
document.write(html)
try While (x := document.getElementsByTagName("strong")[A_Index-1])
{
StringLen, y, % test[A_Index]
msgbox % [A_Index] . " " . substr(x.parentnode.innerText, y+2)
}
}
ExitApp
推荐答案
尝试一下:
html =
(
<body>
<ul class="article-additional-info">
<li><strong>Issue Year:</strong> 2011</li>
<li><strong>Issue No:</strong> 1 (200)</li>
<li><strong>Page Range:</strong> 65-80</li>
<li><strong>Page Count:</strong> 15</li>
<li><strong>Language:</strong> Polish</li>
</ul>
<ul class="article-additional-info">
<li><strong>Issue Year:</strong> XX 2011</li>
<li><strong>Issue No:</strong> XX 1 (200)</li>
<li><strong>Page Range:</strong> XX 65-80</li>
<li><strong>Page Count:</strong> XX 15</li>
<li><strong>Language:</strong> XX Polish</li>
</ul>
</body>
)
test := "Language:" ; adjust for the variable you want to return
classno := 1 ; adjust the number for the correct class instance!
document := ComObjCreate("HTMLfile")
document.write(html)
try While (x := document.getElementsByTagName("ul")[A_Index-1])
{
if (x.className = "article-additional-info")
yclass%A_Index% := x.innerHTML
}
html := yclass%classno%
document.Close
document := ComObjCreate("HTMLfile")
document.write(html)
try While (x := document.getElementsByTagName("strong")[A_Index-1])
{
StringLen, y, test
if (x.innerText = test)
msgbox % substr(x.parentnode.innerText, y+2) ; returns "Polish"
}
ExitApp
而且，如果要遍历所有类实例和所有变量，则可以这样做:
And, if you want to iterate over all the class instances and for all the variables, just do it like so:
html =
(
<body>
<ul class="article-additional-info">
<li><strong>Issue Year:</strong> 2011</li>
<li><strong>Issue No:</strong> 1 (200)</li>
<li><strong>Page Range:</strong> 65-80</li>
<li><strong>Page Count:</strong> 15</li>
<li><strong>Language:</strong> Polish</li>
</ul>
<ul class="ao">
<li><strong>Issue Year:</strong> zz 2011</li>
<li><strong>Issue No:</strong> zz 1 (200)</li>
<li><strong>Page Range:</strong> zz 65-80</li>
<li><strong>Page Count:</strong> zz 15</li>
<li><strong>Language:</strong> zz Polish</li>
</ul>
<ul class="article-additional-info">
<li><strong>Issue Year:</strong> XX 2011</li>
<li><strong>Issue No:</strong> XX 1 (200)</li>
<li><strong>Page Range:</strong> XX 65-80</li>
<li><strong>Page Count:</strong> XX 15</li>
<li><strong>Language:</strong> XX Polish</li>
</ul>
</body>
)
document := ComObjCreate("HTMLfile")
document.write(html)
; To skip a variable, change it to: "" (as shown, where only first 3 are shown
test := ["Issue Year:", "Issue No:", "Page Range:", "", ""]
try While (x := document.getElementsByTagName("ul")[A_Index-1])
{
if (x.className = "article-additional-info")
{
count++
yclass%count% := x.innerHTML
}
}
loop, %count%
{
which++
html := yclass%A_Index%
document.Close
document := ComObjCreate("HTMLfile")
document.write(html)
try While (x := document.getElementsByTagName("strong")[A_Index-1])
{
StringLen, y, % test[A_Index]
if (test[A_Index] <> "")
msgbox % which . ": " . test[A_Index] . " " . substr(x.parentnode.innerText, y+2)
}
}
ExitApp
substr(x.parentnode.innerText, y+2)是您要查找的值.
玩得开心！
