将xml文档作为参数传递给xsl

本文介绍了将xml文档作为参数传递给xsl的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经阅读了很多文章，并尝试了很多事情，但是仍然无法使xsl在参数中找到值.我从java的sun xalan开始，但从未成功，所以我改用saxon徒劳无功.我想将两个xml文档与xls合并为一个.永远不会在文件系统上，这是用于构建xml字符串/docs的Web应用程序.我尝试将DTMAxisIterator，DomSource，Doc传递给以xsl，字符串设置的Node.在NotePad ++中使用xsl document()可以正常工作，但是我不想将xml保存在系统上.

I have read a lot of post and tried a lot of things but still can't get the xsl to find values in the parameter. I started with java's sun xalan and never got it working so I switched to saxon to no avail. I want to combine two xml docs into one with xls. Never are on a file system, this is for a web app that builds xml strings/ docs. I have tried passing an DTMAxisIterator, DomSource , Doc to Node set in xsl, string. It worked fine in NotePad++ with an xsl document() but I don't want to save the xml on the system.

XSL

XML One

<?xml version="1.0" encoding="UTF-8"?> <policy id="1735"> <vehicles> </vehicles> </policy>

XML 2

推荐答案

我能够与Saxon一起使用，请参见下面的代码.我认为关键是document.getDocumentElement()为parm

I was able to get it work with Saxon see below code. I think the key was the document.getDocumentElement() as parm

public String transformResultXML(String xmlSource, Templates xsl,String policyXml ) { String result = ""; try { StringWriter writer = new StringWriter(); StringReader reader2 = new StringReader(policyXml); DocumentBuilderFactory dfactory = DocumentBuilderFactory.newInstance( "com.icl.saxon.om.DocumentBuilderFactoryImpl",null); dfactory.setNamespaceAware(true); DocumentBuilder docBuilder = dfactory.newDocumentBuilder(); org.w3c.dom.Document document = docBuilder.parse(new InputSource(new StringReader(xmlSource))); Transformer transformer = xsl.newTransformer(); transformer.setParameter("RsXml", document.getDocumentElement()); transformer.setOutputProperty(OutputKeys.INDENT, "yes"); transformer.transform(new javax.xml.transform.stream.StreamSource(reader2), new javax.xml.transform.stream.StreamResult(writer)); result = writer.toString(); System.out.println(result); } catch( Exception e ) { e.printStackTrace(); }

XSL代码段

<xsl:param name="RsXml" /> <xsl:template match="/policy/vehicles"> <xsl:for-each select="$RsXml/InsuranceSvcRs/com.csc_PolicyOrderCurrentCarrierInqRs/PersVeh">
