我正在嘗試執行以下a)或b)。我寧願a),如果我能弄明白的話。 請參考最後的html。從html中提取特定元素/值
a)提取以下項目的值 - 「」中的項目是靜態的,但關聯的值將會改變。我只想提取價值。
"locality" = Paris
"region" = Paris
"country-name" = France
"latitude" = 48.85534
"longitude" = 2.35048
二)簡單的提取整個元素<div class="vcard">...<div>
我試圖重新使用別人的代碼,並使它做我想做的。但是我在編寫代碼時遇到了麻煩。我設法提取一些值。但它很混亂。我覺得代碼可以做得更要好得多:
的VBA
Sheet1.WebBrowser1.Navigate (Sheet1.Range("C1"))
Do
DoEvents
Loop Until Sheet1.WebBrowser1.ReadyState = READYSTATE_COMPLETE
the_html_code = Sheet1.WebBrowser1.Document.Body.InnerHTML
the_output_row = 2
start_of_item = InStr(the_html_code, "locality")
the_value = Mid(the_html_code, start_of_item + 39, Len(the_html_code))
the_html_code = Mid(the_html_code, start_of_item + 8, Len(the_html_code))
the_value = Mid(the_value, 1, InStr(the_value, Chr(62)) - 1)
Sheet1.Range("L" & the_output_row) = the_value
的HTML
<script>
if (typeof (aadSponsoredLinksObj) != 'undefined' && aadSponsoredLinksObj.type == 'google' && aadSponsoredLinksObj.show_links == true) {
document.write('<scr' + 'ipt src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></scr' + 'ipt>');
} else if (typeof (aadSponsoredLinksObj) == 'undefined') {
jQuery('#ad-links').remove();
}
</script>
<div id="tracking-pixels"></div>
</div>
<!-- /#wrap -->
<div class="vcard">

</span>
<span class="longitude">
<span class="value-title" title="2.35048"></span>
</span>
</span>
</div>
<script type="text/javascript">
var _qoptions = { qacct: 'p-4b4gl_1fWISuU' };
if (typeof (apgPageInfoObj) != 'undefined' && apgPageInfoObj.crumb_trail) {
_qoptions.labels = apgPageInfoObj.crumb_trail.join('.');
爲什麼不使用適當的DOM解析器?這將比嘗試使用字符串函數解析HTML的效率高出約1000%。 –
