<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'>

  • Maybe this can help you for the a href. Also, you should get element, you can use lot of things such as document.getElementById Commented Nov 15, 2021 at 9:31
  • Do you want to extract all href values from all trs with class textData or all hrefs all together, the answer will depend on which hrefs you want to select and it's not clear from the question Commented Nov 15, 2021 at 9:40
  • @AntonBelev , yes all hrefs Commented Nov 15, 2021 at 9:42
  • There are three tags with the attribute href. Why don't you handle all three? Thu, 05 Jan 2017 11:11:14 GMT has nothing to do with the attribute href. How do you identify it? Commented Nov 15, 2021 at 9:42
  • @Elikill58 this solution is for javaScript , i want to get a solution with java Commented Nov 15, 2021 at 9:46

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'>&nbsp;</td><td class='textData'>&nbsp;</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'>&nbsp;</td><td class='textData'>&nbsp;</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'>&nbsp;</td><td class='textData'>&nbsp;</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
