Xslt RSS查看器自定义以删除部分呈现的文本-SharePoint 2010
我正在尝试自定义RSS提要中的项目在我的RSS查看器web部件中的显示方式。我想阻止web部件在省略号（…）之后显示所有内容。例如，下面的文本是使用Google News RSS提要的“我的测试RSS查看器”页面中的描述： 新罕布什尔州之行让我们一窥沃克和布什之间可能存在的竞争 NPR 两位可能的共和党总统候选人，威斯康星州州长斯科特·沃克和前佛罗里达州州长杰布·布什，本周末访问了新罕布什尔州。虽然两人都没有正式宣布参选，《波士顿环球报》的詹姆斯·平德尔说他们。。。 当人们问杰布关于印度的布什王朝时，他是这么说的 杰布·布什已不再被关注，他将于周四参观州议会大厦。《宪法》杂志（博客） 斯科特·沃克·帕克：杰布·布什不是唯一一个能为CNN国际筹款的人 新罕布什尔州公共广播电台-佩托斯基新闻评论 所有82篇新闻文章» 我想删除“…”之后的所有内容，因此页面将显示： 新罕布什尔州之行让我们一窥沃克和布什可能的竞争对手NPR两位可能的共和党总统候选人，威斯康星州州长斯科特·沃克和前佛罗里达州州长杰布·布什，本周末访问了新罕布什尔州。虽然两人都没有正式宣布参选，《波士顿环球报》的詹姆斯·平德尔说他们 我过去没有真正使用过XSLT或XML，因此这对我来说相当困难。我在SharePoint StackExchange上问了一个类似的问题，但还没有回答，所以我想我也会在这里发布。谢谢您的帮助 编辑 代码如下：Xslt RSS查看器自定义以删除部分呈现的文本-SharePoint 2010,xslt,sharepoint-2010,web-parts,sharepoint-designer,rss-reader,Xslt,Sharepoint 2010,Web Parts,Sharepoint Designer,Rss Reader,我正在尝试自定义RSS提要中的项目在我的RSS查看器web部件中的显示方式。我想阻止web部件在省略号（…）之后显示所有内容。例如，下面的文本是使用Google News RSS提要的“我的测试RSS查看器”页面中的描述： 新罕布什尔州之行让我们一窥沃克和布什之间可能存在的竞争 NPR 两位可能的共和党总统候选人，威斯康星州州长斯科特·沃克和前佛罗里达州州长杰布·布什，本周末访问了新罕布什尔州。虽然两人都没有正式宣布参选，《波士顿环球报》的詹姆斯·平德尔说他们。。。 当人们问杰布关于印度的布什王
