Converting a Cognos XML Schema file to XML using Javascript code

问题:

I found many "converters" online that will do this for you, but I haven't been able to find any source code that I can easily implement. I was wondering if anyone would be so kind to provide me with suggestions or even provide me with code that will do this task for me. I am trying to convert to XML so it will be easier to parse.

I am trying to convert this (Cognos XML Schema)...

  <?xml version="1.0" encoding="utf-8" ?>  - <dataset xmlns="http://developer.cognos.com/schemas/xmldata/1/" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"> - <!--  <dataset     xmlns="http://developer.cognos.com/schemas/xmldata/1/"     xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"     xs:schemaLocation="http://developer.cognos.com/schemas/xmldata/1/ xmldata.xsd" >   -->  - <metadata>   <item name="ROOT_NODE_ID" type="xs:decimal" precision="38" />    <item name="LEVEL1_ID" type="xs:string" length="2002" />    <item name="LEVEL1_NAME" type="xs:string" length="512" />    <item name="LEVEL2_ID" type="xs:string" length="2002" />    <item name="LEVEL2_NAME" type="xs:string" length="512" />    <item name="LEVEL3_ID" type="xs:string" length="2002" />    <item name="LEVEL3_NAME" type="xs:string" length="512" />    <item name="LEVEL4_ID" type="xs:string" length="2002" />    <item name="LEVEL4_NAME" type="xs:string" length="512" />    <item name="LEVEL5_ID" type="xs:string" length="2002" />    <item name="LEVEL5_NAME" type="xs:string" length="512" />    <item name="LEVEL6_ID" type="xs:string" length="2002" />    <item name="LEVEL6_NAME" type="xs:string" length="512" />    <item name="LEVEL7_ID" type="xs:string" length="2002" />    <item name="LEVEL7_NAME" type="xs:string" length="512" />    <item name="LEVEL8_ID" type="xs:string" length="2002" />    <item name="LEVEL8_NAME" type="xs:string" length="512" />    <item name="LEVEL9_ID" type="xs:string" length="2002" />    <item name="LEVEL9_NAME" type="xs:string" length="512" />    <item name="LEVEL10_ID" type="xs:string" length="2002" />    <item name="LEVEL10_NAME" type="xs:string" length="512" />    </metadata> - <data> - <row>   <value>5</value>    <value>5</value>    <value>Global Root</value>    <value>41</value>    <value>Company</value>    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    </row> - <row>   <value>5</value>    <value>5</value>    <value>Global Root</value>    <value>41</value>    <value>Company</value>    <value>101590</value>    <value>Customer</value>    <value>101591</value>    <value>Customer -All Sites</value>    <value>125083</value>    <value>Site 1</value>    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    <value xs:nil="true" />    </row>   </data>   </dataset> 

To this (XML)....

<?xml version="1.0" encoding="UTF-8"?> <rows>   <row>     <ROOT_NODE_ID>5</ROOT_NODE_ID>     <LEVEL1_ID>5</LEVEL1_ID>     <LEVEL1_NAME>Global Root</LEVEL1_NAME>     <LEVEL2_ID>41</LEVEL2_ID>     <LEVEL2_NAME>Company</LEVEL2_NAME>     <LEVEL3_ID></LEVEL3_ID>     <LEVEL3_NAME></LEVEL3_NAME>     <LEVEL4_ID></LEVEL4_ID>     <LEVEL4_NAME></LEVEL4_NAME>     <LEVEL5_ID></LEVEL5_ID>     <LEVEL5_NAME></LEVEL5_NAME>     <LEVEL6_ID></LEVEL6_ID>     <LEVEL6_NAME></LEVEL6_NAME>     <LEVEL7_ID></LEVEL7_ID>     <LEVEL7_NAME></LEVEL7_NAME>     <LEVEL8_ID></LEVEL8_ID>     <LEVEL8_NAME></LEVEL8_NAME>     <LEVEL9_ID></LEVEL9_ID>     <LEVEL9_NAME></LEVEL9_NAME>     <LEVEL10_ID></LEVEL10_ID>     <LEVEL10_NAME></LEVEL10_NAME>  </row>  <row>     <ROOT_NODE_ID>5</ROOT_NODE_ID>     <LEVEL1_ID>5</LEVEL1_ID>     <LEVEL1_NAME>Global Root</LEVEL1_NAME>     <LEVEL2_ID>41</LEVEL2_ID>     <LEVEL2_NAME>Company</LEVEL2_NAME>     <LEVEL3_ID>101590</LEVEL3_ID>     <LEVEL3_NAME>Customer</LEVEL3_NAME>     <LEVEL4_ID>101591</LEVEL4_ID>     <LEVEL4_NAME>Customer -All Sites</LEVEL4_NAME>     <LEVEL5_ID>125083</LEVEL5_ID>     <LEVEL5_NAME>Site 1</LEVEL5_NAME>     <LEVEL6_ID></LEVEL6_ID>     <LEVEL6_NAME></LEVEL6_NAME>     <LEVEL7_ID></LEVEL7_ID>     <LEVEL7_NAME></LEVEL7_NAME>     <LEVEL8_ID></LEVEL8_ID>     <LEVEL8_NAME></LEVEL8_NAME>     <LEVEL9_ID></LEVEL9_ID>     <LEVEL9_NAME></LEVEL9_NAME>     <LEVEL10_ID></LEVEL10_ID>     <LEVEL10_NAME></LEVEL10_NAME>   </row> </rows> 

回答1:

This Xslt strip any schema metadata from arbitrary Cognos reports - Xml output method - and create result elements with names extracted from the metadata:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns="http://tempuri.org/" xmlns:cog="http://developer.cognos.com/schemas/xmldata/1/" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">     <xsl:output method="xml" indent="yes" />      <xsl:template match="//comment()" />      <xsl:template match="/">         <xsl:apply-templates />     </xsl:template>      <xsl:template match="cog:dataset">         <rows>             <xsl:apply-templates />         </rows>     </xsl:template>      <xsl:template match="cog:metadata">         <xsl:apply-templates />     </xsl:template>      <xsl:template match="cog:item">         <xsl:apply-templates />     </xsl:template>      <xsl:template match="@name | @type | @length | @precision" />      <xsl:template match="cog:data">         <xsl:apply-templates />     </xsl:template>      <xsl:template match="cog:row">         <row>             <xsl:apply-templates />         </row>     </xsl:template>      <xsl:template match="cog:value">         <xsl:variable name="currentposition" select="count(./preceding-sibling::cog:value)+1" />         <xsl:variable name="currentname" select="//cog:metadata/cog:item[$currentposition]/@name" />         <xsl:element name="{$currentname}">             <xsl:apply-templates />         </xsl:element>     </xsl:template>      <xsl:template match="@* | node()">         <xsl:copy>             <xsl:apply-templates select="@* | node()"/>         </xsl:copy>     </xsl:template> </xsl:stylesheet> 

If however you want to make Cognos apply a server-side transformation, you'll have to choose the XHTML output method which will make the transformation a little easier since each field will carry its actual name instead of value.
