ANd , i'm trying to get the href of each tag .
For example ,
<table cellspacing='2' cellpadding='3' border='0' width='100%'>
<tr><td colspan='4' class='textLocation'>Directory listing for /rep</td></tr>
<tr><td height='10' colspan='4'></td></tr></table><table cellspacing='2' cellpadding='3' border='0' width='100%' class='listingTable'>
<tr><td class='tableHeading' width='*'>Name</td><td class='tableHeading' width='10%'>Size</td><td class='tableHeading' width='20%'>Type</td><td class='tableHeading' width='25%'>Modified Date</td></tr>
<tr class='rowOdd'><td class='textData'><a href="/alfresco/webdav/rep/ED">ED</a></td><td class='textData'> </td><td class='textData'> </td><td class='textData'>Thu, 05 Jan 2017 11:11:14 GMT</td></tr>
I want to extract "/alfresco/webdav/rep/ED" and "ED" and "Thu, 05 Jan 2017 11:11:14 GMT"
First you need to parse the html which is String to Document.
final Document document = Jsoup.parse(html);
Then you need to select all tr
tags which contains a
tag.
final Elements trElements = document.select("tr:has(a)");
After, you need to browse each tr
tag found :
for (final Element trElement : trElements) {
//Do stuff
}
For each tr tag, you retrieve the href
value of tag. But first, you need to retrieve the a
tag :
final Element aElement = trElement.select("a").first();
Then, we retrieve, the value of href
attribute in tag a
.
final String href = aElement.attr("href");
For name, you retrieve the text content of a
tag :
final String name = aElement.text();
For date, you need to retrieve the fourth td
tag from tr
tag :
final Element dateTdElement = trElement.select("td").get(3);
And just retrieve the value text to get the date content :
final String date = dateTdElement.text();
NB : The method select()
accept a css query. All css query is valid with extended syntax like ':has()' and other part. See Jsoup documention for more detail.
To resume all in one code :
public static void main(final String[] args) {
final String html = "<html><head><title>Alfresco Content Repository</title><style>body { font-family: Arial, Helvetica; font-size: 12pt; background-color: white; }\n" +
"table { font-family: Arial, Helvetica; font-size: 12pt; background-color: white; }\n" +
".listingTable { border: solid black 1px; }\n" +
".textCommand { font-family: verdana; font-size: 10pt; }\n" +
".textLocation { font-family: verdana; font-size: 11pt; font-weight: bold; color: #2a568f; }\n" +
".textData { font-family: verdana; font-size: 10pt; }\n" +
".tableHeading { font-family: verdana; font-size: 10pt; font-weight: bold; color: white; background-color: #2a568f; }\n" +
".rowOdd { background-color: #eeeeee; }\n" +
".rowEven { background-color: #dddddd; }\n" +
"</style></head>\n" +
"<body>\n" +
"<table cellspacing='2' cellpadding='3' border='0' width='100%'>\n" +
"<tr><td colspan='4' class='textLocation'>Directory listing for /rep</td></tr>\n" +
"<tr><td height='10' colspan='4'></td></tr></table><table cellspacing='2' cellpadding='3' border='0' width='100%' class='listingTable'>\n" +
"<tr><td class='tableHeading' width='*'>Name</td><td class='tableHeading' width='10%'>Size</td><td class='tableHeading' width='20%'>Type</td><td class='tableHeading' width='25%'>Modified Date</td></tr>\n" +
"<tr class='rowOdd'><td class='textData'><a href=\"/alfresco/webdav/rep/ED\">ED</a></td><td class='textData'> </td><td class='textData'> </td><td class='textData'>Thu, 05 Jan 2017 11:11:14 GMT</td></tr>\n" +
"<tr class='rowEven'><td class='textData'><a href=\"/alfresco/webdav/rep/FLOW%20CHART\">FLOW CHART</a></td><td class='textData'> </td><td class='textData'> </td><td class='textData'>Thu, 27 Jun 2013 13:30:18 GMT</td></tr>\n" +
"<tr class='rowOdd'><td class='textData'><a href=\"/alfresco/webdav/rep/file\">file</a></td><td class='textData'> </td><td class='textData'> </td><td class='textData'>Wed, 10 Nov 2021 13:16:49 GMT</td></tr>\n" +
"\n" +
"\n" +
"</table></body></html>";
final Document document = Jsoup.parse(html);
final Elements trElements = document.select("tr:has(a)");
for (final Element trElement : trElements) {
final Element aElement = trElement.select("a").first();
final String href = aElement.attr("href");
System.out.println("Href : " + href);
final String name = aElement.text();
System.out.println("Name : " + name);
final Element dateTdElement = trElement.select("td").get(3);
final String date = dateTdElement.text();
System.out.println("Date : " + date);
}
}
It prints something like :
Href : /alfresco/webdav/rep/ED
Name : ED
Date : Thu, 05 Jan 2017 11:11:14 GMT
Href : /alfresco/webdav/rep/FLOW%20CHART
Name : FLOW CHART
Date : Thu, 27 Jun 2013 13:30:18 GMT
Href : /alfresco/webdav/rep/file
Name : file
Date : Wed, 10 Nov 2021 13:16:49 GMT
