Since then we have had the admission of Victrex and, as of last week, Elementis and Yule Catto. Having met management, we believe that Elementis has all the ingredients for value creation that Croda has so successfully exhibited.</span></p>

It has not just got there through a cyclical bounce back either. The company has gone through a very sensible rationalisation programme, exited a low-returning business (UK Chromium), is running much more efficient levels of working capital, and crucially, is more exposed to growth markets. To give an idea of managementès resolve, instead of selling the UK Chromium business they decided to effectively bulldoze the site. This will prevent a competitor from interfering in Elementisè position in US Chromium.</span></p>

Deuchem has 12 offices in<?xml:namespace prefix = st1 /><st1:country-region><st1:place>China</st1:place></st1:country-region><span class="Apple-converted-space">&nbsp;</span>and is benefiting as the Chinese customer moves up the quality/performance scale. Previously, Chinese demand was not for sophisticated products è this is changing as we type. Coatings are the main market for speciality products, with Oilfield Chemicals the next biggest category. The cost of Elementisè products per end unit remains small, typically <5%. Yet the relationship with the customer (its largest is Akzo Nobel) is generally one that has been forged over many years (even decades) and required them to work closely together. In short, it is not particularly competitive, but does require consistent delivery and performance from Elementis. We have a very conservative top-line growth forecast of 3% for specialty chemicals, yet would not be surprised if it was nearer 5%. Margin progression here is key and we expect a mid-to-high teens margin up from 9%.</span></p>

Typically, drilling was vertical. But, now drill bits can be turned 90 degrees accessing much more of the shale seam. This requires much more lubricant è hence H1 2010 volumes were double the year before. There is only one competitor in this area. Elsewhere in the US Elementis has its US Chromium business. This is steady, has high<span class="Apple-converted-space">&nbsp;</span><st1:country-region>US</st1:country-region><span class="Apple-converted-space">&nbsp;</span>market shares and has a superior transport advantage to competitors exporting to the<span class="Apple-converted-space">&nbsp;</span><st1:country-region><st1:place>US</st1:place></st1:country-region>.

谁能告诉我如何解析特殊字符和 html 标签？

任何帮助将不胜感激

Answer 1

我复制了您的示例，对其进行了格式化，恕我直言，我理解了这个问题。您的 XML 是包含 HTML 的 SOAP 响应。 HTML 由标签 ARTICLE 的属性 BODY 保存。

XML 标签的内容不能包含多个禁止字符，如 "、'、<、> 等。但您的内容包含很多此类字符，因为它是 HTML。要发送 HTML，您必须转义禁止字符，即替换< 由 <

by > ' by & " by &qout;

我的意思是在生成响应时执行此操作，而不是在解析响应时执行!祝你好运。
