我在學習如何使用XMLStarlet訪問Bash中HTML標記的內容。作爲一個例子,我試圖訪問www.wisdomofchopra.com/iframe.php頁面中的一些文本。我在指定XMLStarlet的HTML內容的「地址」時遇到了一些困難,並且會提供一些幫助。我的代碼嘗試以下:如何使用XMLStarlet訪問Bash中HTML標記的內容
URL="http://www.wisdomofchopra.com/iframe.php"
webPage="$(curl -s "${URL}")"
echo "${webPage}" | xmlstarlet sel -T -t -c "//html/body//table/tr/td[@id='quote']/header/h2/"
這將產生以下的輸出:
-:29.12: Opening and ending tag mismatch: meta line 5 and head
</head>

編輯:爲方便起見,以下是網頁一些大致相當於HTML代碼:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h3>Your random fictional Deepak Chopra quote:</h3>
<table border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="128" align="left" valign="top"><img src="img/imageSmall2.png" width="80" height="80" /></td>
<td id="quote"><header><h2>"Perceptual reality serves total truth" </h2></header></td>
</tr>
</table>
</body>
</html>
感謝您的建議。我不認爲這是問題。我創建了一個與示例網頁分層相似的代碼,我仍遇到類似的問題。我已將此簡化版本添加到發佈文字中。 – d3pd 2014-09-23 20:32:55
