如何通过 shell 脚本从 HTML 数据中获取整行？

Question

我需要从 table 中获取整行，因为我已将 table 数据转换为 HTML 格式（请参阅下面的数据）。现在我需要获取特定行的数据 Ex 假设我想要 19.8.2 的数据然后 whole ROW 应该从 8/19/19（Branch cut）到 8/23 获取/19（产品部署）--

<div class="table-wrap">
    <table class="wrapped confluenceTable">
        <colgroup>
            <col style="width: 123.0px;" />
            <col style="width: 80.0px;" />
            <col style="width: 138.0px;" />
            <col style="width: 138.0px;" />
            <col style="width: 139.0px;" />
            <col style="width: 126.0px;" />
            <col style="width: 788.0px;" />
        </colgroup>
        <tbody>

我尝试使用以下脚本，但得到的输出只是分支切割列日期 - 请帮忙。

#!/bin/bash
curl -user -pass --noproxy '*' 'https://confluence.es.com/display/Release+Calendar' | awk ' /<div id="main-content" class="wiki-content">/ {flag=1;next} /        <\/div>/{flag=0} flag { print }' > page.tmp
xmllint --html -xpath'//table/tbody/tr/td[2]' page.tmp | egrep -o '[0-9]{1,2}/[0-9]{1,2}/[0-9]{2,4}' > branchdates.tmp

Answer 1

您必须获得必需的 td，然后是该 td 的父级 tr。您可以使用以下 xpath

获得要求td

//table//td[contains(text(), '19.8.2')]

获取所需 td

的父级 tr

//table//td[contains(text(), '19.8.2')]/parent::tr
