Question

我有以下HTML代码：

<div id="ipsLayout_contentArea">
<div class="preContentPadding">
<div id="ipsLayout_contentWrapper">
<div id="ipsLayout_mainArea">
<a id="elContent"></a>
<div class="cWidgetContainer " data-widgetarea="header" data-orientation="horizontal" data-role="widgetReceiver" data-controller="core.front.widgets.area">
<div class="ipsPageHeader ipsClearfix">
<div class="ipsClearfix">
<div class="cTopic ipsClear ipsSpacer_top" data-feedid="topic-100269" data-lastpage="" data-baseurl="https://forum.com/forum/topic/100269-topic/" data-autopoll="" data-controller="core.front.core.commentFeed,forums.front.topic.view">
<div class="" data-controller="core.front.core.moderation" data-role="commentFeed">
<form data-role="moderationTools" data-ipspageaction="" method="post" action="https://forum.com/forum/topic/100269-topic/?csrfKey=b092dccccee08fdbc06c26d350bf3c2b&do=multimodComment">
<a id="comment-626016"></a>
<article id="elComment_626016" class="cPost ipsBox ipsComment ipsComment_parent ipsClearfix ipsClear ipsColumns ipsColumns_noSpacing ipsColumns_collapsePhone " itemtype="http://schema.org/Comment" itemscope="">
<aside class="ipsComment_author cAuthorPane ipsColumn ipsColumn_medium">
<div class="ipsColumn ipsColumn_fluid">
<div id="comment-626016_wrap" class="ipsComment_content ipsType_medium ipsFaded_withHover" data-quotedata="{"userid":3859,"username":"Admin","timestamp":1453221383,"contentapp":"forums","contenttype":"forums","contentid":100269,"contentclass":"forums_Topic","contentcommentid":626016}" data-commentid="626016" data-commenttype="forums" data-commentapp="forums" data-controller="core.front.core.comment">
<div class="ipsComment_meta ipsType_light">
<div class="cPost_contentWrap ipsPad">
<div class="ipsType_normal ipsType_richText ipsContained" data-controller="core.front.core.lightboxedImages" itemprop="text" data-role="commentContent">
<p> Hi, </p>
<p>   </p>
<p> This is a post with multiple </p>
<p> lines of text </p>

我正在尝试获取帖子的内容（以明文形式）。我正在使用的XPath：

//div[@id='ipsLayout_contentArea']/div[2]/div/div[4]/div/form/article/div/div/div[2]/div//text()

检索每个帖子的每一行（由分隔）。如何获得帖子的全部内容（内部：

<div class="ipsType_normal ipsType_richText ipsContained" data-controller="core.front.core.lightboxedImages" itemprop="text" data-role="commentContent"> Post content </div>),

明文

（以便将视为文本（以及帖子可能包含的其他标签））？

修改

我正在使用以下XPath：

//div[@id='ipsLayout_contentArea']/div[2]/div/div[4]/div/form/article/div/div/div[2]/div

检索包含帖子正文的div。

// forumTemplate.getXpathElements().get(forumTemplate.XPATH_GET_THREAD_POSTS) = //div[@id='ipsLayout_contentArea']/div[2]/div/div[4]/div/form/article/div/div/div[2]/div
List<DomNode> posts = (List<DomNode>) firstPage.getByXPath(forumTemplate.getXpathElements().get(forumTemplate.XPATH_GET_THREAD_POSTS));
                for (DomNode post : posts) {
                    // Retrieve the contents of the post as a string
                    String postContentStr = post.getNodeValue();

变量postContentStr始终为null。为什么呢？

Answer 1

您指定了//text()，它将以递归方式获取指定路径下的所有文本节点。根据您的使用情况，这可能会更好：

//div[@data-role='commentContent']

这将匹配您尝试获取的评论节点。如果您使用代码进行评估，可以从这里开始。但是，请不要与text()匹配，这与个代码中的任何一个都不匹配。

使用XPath检索html标签的内容
