我不喜欢regex在coldfusion，任何人都可以指导我或给我任何起点如何从html表提取数据使用Coldfusion？我没有访问DB。希望这是清楚的。
解决方案
使用正则表达式解析HTML？如果您使用jsoup HTML解析器w / ColdFusion，您将有更多的选择。 Jsoup使用类似jQuery的DOM选择器，可以快速将HTML表格数据转换为数组。
以下是一些相关文章&示例代码：

I am trying to screen scrape another application using the below code in Coldfusion.
<cfhttp url="https://intra.att.com/itscmetrics/EM2/LTMR.cfm" method="get" username="uvwxyz" password="abcdef">
<cfhttpparam type="url" name="LTMX" value="Andre Fuetsch / Shelly K Lazzaro">
</cfhttp>
<cfset myDocument = cfhttp.fileContent>
<cfoutput>
#myDocument#
</cfoutput>
Now when I run my cfm page, iam able to access the desitination page, with the above code. The destination page looks like below.
A part of the source code of this is as below.
<table border="1" width=99% style="border-collapse:collapse;">
<thead>
<td colspan="12" class="drpmainheader1_2">LTM Detail Report for Andre Fuetsch / Shelly K Lazzaro</td>
<tr align="center">
<th class="ptitles">Liaison Name</th>
<th class="ptitles">Application Acronym</th>
<th class="ptitles">MOTS ID</th>

I am not good with regex in coldfusion, Can anyone please guide me or give me any starting points as to how to extract the data from the html table using Coldfusion? I do not have access to the DB. Hope this is clear.
解决方案
Parsing HTML using regex? You'll have more options if you use the jsoup HTML Parser w/ColdFusion. Jsoup uses jQuery-like DOM selectors and can quickly convert the HTML table data into arrays.
Here are some related articles & sample code:
