Question

我正在使用Banxico Web Services并返回一个字符串，在该字符串中有XML。

我真正需要的是使用XSLT或XPath提取下一部分。

如何使用XSLT或Xpath？

PesospordólarE.U.A。 Tipo de cambio para solventar obligaciones denominadas en moneda extranjera Fecha dedeterminación（FIX）“ IDSERIE =“SF43718”BANXICO_FREQ =“Dia”BANXICO_FIGURE_TYPE =“TipoCambio” BANXICO_UNIT_TYPE = “PesoxDoll” ＆GT;

 public class OAuth2ServerConfiguration extends ResourceServerConfigurerAdapter {

        @Override
        public void configure(ResourceServerSecurityConfigurer resources) {

            // ...set up token store here

            resources.authenticationEntryPoint(new AuthenticationEntryPoint() {
                @Override
                public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException {

                 //QUESTION
                 // How do I get the destination controller that this request was going to go to?
                 // Really, I'd like to get some information about the annotations that were on the destination controller.

                    response.setStatus(401);
                }
            });
        }

通过该响应，我构建了一个xsd模式。

Answer 1

要运行XSL转换以提取所需信息，您不需要生成架构。

如果你可以使用XPath 3函数，你可以一次完成所有这些：XPath 3包含一个解析字符串并将其转换为逻辑XML树的函数，然后允许你对它运行XPath表达式。 / p>

如果您不能使用XPath 3函数，那么您需要在两次传递中执行此操作：仅导出<result>文本内容（您希望进一步处理的XML响应）到一个单独的文件，然后加载该文件并在其上运行另一个转换以提取您想要的内容。

以下是使用XPath 3在一次传递中处理此问题的快速而肮脏的示例。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="xs"
    version="3.0">

    <!-- Start at the document node / and set up the outermost element -->
    <xsl:template match="/">
        <!-- Change this element name to whatever makes sense for you -->
        <BanxicoReply>
            <!-- The input file only has one "result", 
                and that's all we want, so grab it -->
            <xsl:apply-templates select="//result"/>
        </BanxicoReply>
    </xsl:template>

    <xsl:template match="result">
        <!-- Parse the CDATA content to turn it into XML -->
        <xsl:variable name="contained-xml" select="parse-xml(./text())"/>

        <!-- Do what you need to here.
            This example just plucks out the one chunk
            you identified at the top of your post. 

            Note the "*:Series" shorthand: this matches
            any "Series" element in any namespace.  This 
            is an admittedly sloppy shortcut, which could
            be dangerous in other contexts - but here, in
            this one file, it's safe, and this avoids the 
            need for us to explicitly declare the "bm:" 
            namespace prefix in this XSL. -->
        <xsl:copy-of select="$contained-xml//*:Series[@IDSERIE='SF43718']"/>
    </xsl:template>

    <!-- Suppress output of all other elements -->
    <xsl:template match="*"/>

</xsl:stylesheet>

使用上面的XML作为输入，此XSL产生以下结果（缩进以便于人类易读性）：

<?xml version="1.0" encoding="UTF-8"?>

Answer 2

我建议使用JSON API https://www.banxico.org.mx/SieAPIRest而不是旧的soap服务。
