Question

cffile write to xml

Asked by: judsonmusic

i have the folling code that write to an xml file:
<cfoutput>
<CFXML variable="event">
<event>
            <date>#form.date#</date>
            <time>#form.time#</time>
            <title>#form.title#</title>
            <image>images/kiss.jpg</image>
            <description>
                   <![CDATA[#form.description#]]>
            </description>
            <link><![CDATA[]]></link>
      </event>
</CFXML>
</cfoutput>
<cffile action="append" charset="utf-8" file = "D:\Hosting\knicknoc\thinkboxstudios\admin\events\kiss\events.xml" output = "<events>#event#</events>" >
This is the file that was generated:
<br>
<br>
<cfdump var="#event#">

everytime I append to the page it recreates the <?xml version="1.0" encoding="UTF-8"?> and also i want it to append between 2 the events tags as you see below, no matter how many times they do the <event> write or append. What do I need to do???
i need to change it so that it will write into a page like this:
<?xml version="1.0" encoding="UTF-8"?>
<events>
<event>
            <date>01/03/2001</date>
            <time>9:30p</time>
            <title>test2</title>
            <image>images/kiss.jpg</image>
            <description>
                   <![CDATA[test description 2]]>
            </description>
            <link/>
      </event>
<event>
            <date>01/03/2001</date>
            <time>9:30p</time>
            <title>test2</title>
            <image>images/kiss.jpg</image>
            <description>
                   <![CDATA[test description 2]]>
            </description>
            <link/>
      </event>

<event>
            <date>01/03/2001</date>
            <time>9:30p</time>

thats not quite it

let say I have this already:

<?xml version="1.0" encoding="UTF-8"?>
<events>
<event>
            <date>01/03/2001</date>
            <time>9:30p</time>
            <title>test2</title>

            <description>
                   <![CDATA[test description 2]]>
            </description>
            <link/>
      </event>
</events>

then they add a new event i want it to append like this:

<?xml version="1.0" encoding="UTF-8"?>
<events>
<event>
<date>01/03/2001</date>
<time>9:30p</time>
<title>test2</title>
<image>images/kiss.jpg</image>
<description>
<![CDATA[test description 2]]>
</description>
<link/>
</event>
:::::::::::::::::::::::::::::::::::::::::this is the new event below and should be inserted here. not creating the new xmlversion, etc. they both will also stay within the <events>tag already on the page.:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
<event>
<date>08/07/2008</date>
<time>10:30p</time>
<title>test3</title>

You're always going to have a hard time "appending" to an xml file because of its nature. If you append to an xml file you in a sense tack something on the end, well xml files usually have a root node, if you append after that you'll have issues.

To fix your issue I would read in your XML document, then append your new elements to the XML structure, then write the file back out. I would never append to the end.

Check this:

<cftry>
  <cfset xmlDoc=xmlParse(ExpandPath("./events.xml")) >
<cfcatch>
  <cfset xmlDoc=xmlNew() >
  <cfset xmlDoc.xmlRoot = xmlElemNew(xmlDoc,"events") >
</cfcatch>
</cftry>
 
<cfscript>
function addXmlNode(xmlDoc, xmlArray, xmlNodeName, xmlNodeText){
  ArrayAppend(xmlArray, xmlElemNew(xmlDoc, xmlNodeName));
  xmlArray[ArrayLen(xmlArray)].xmlText = xmlNodeText;
}
</cfscript>
 
 
<cfset ArrayAppend(xmlDoc.xmlRoot.xmlChildren, xmlElemNew(xmlDoc,"event")) >
<cfset newPos = ArrayLen(xmlDoc.xmlRoot.xmlChildren) >
<cfset addXmlNode(xmlDoc, xmlDoc.xmlRoot.xmlChildren[newPos].xmlChildren, "date","#form.date#") >
<cfset addXmlNode(xmlDoc, xmlDoc.xmlRoot.xmlChildren[newPos].xmlChildren, "time","#form.time#") >
<cfset addXmlNode(xmlDoc, xmlDoc.xmlRoot.xmlChildren[newPos].xmlChildren, "title","#form.title#") >
<cfset addXmlNode(xmlDoc, xmlDoc.xmlRoot.xmlChildren[newPos].xmlChildren, "image","images/kiss.jpg") >
<cfset addXmlNode(xmlDoc, xmlDoc.xmlRoot.xmlChildren[newPos].xmlChildren, "description","#form.description#") >
<cfset addXmlNode(xmlDoc, xmlDoc.xmlRoot.xmlChildren[newPos].xmlChildren, "link","someLink") >
 
  <cffile action="write" charset="utf-8" file = "#ExpandPath("./events.xml")#" output = "#xmlDoc#" >

Perhaps this is slightly better readable:

<cftry>
  <cfset xmlDoc=xmlParse(ExpandPath("./events.xml")) >
<cfcatch>
  <cfset xmlDoc=xmlNew() >
  <cfset xmlDoc.xmlRoot = xmlElemNew(xmlDoc,"events") >

</cftry>
 
<cfscript>
function addXmlNode(xmlObj, xmlNodeName, xmlNodeText){
  xmlArray = xmlObj.xmlRoot.xmlChildren;
  xmlArray = xmlArray[ArrayLen(xmlArray)].xmlChildren;
  ArrayAppend(xmlArray, xmlElemNew(xmlObj, xmlNodeName));
  xmlArray[ArrayLen(xmlArray)].xmlText = xmlNodeText;
}
</cfscript>
 
 
<cfset ArrayAppend(xmlDoc.xmlRoot.xmlChildren, xmlElemNew(xmlDoc,"event")) >
<cfset newPos = ArrayLen(xmlDoc.xmlRoot.xmlChildren) >
<cfset addXmlNode(xmlDoc, "date","#form.date#") >
<cfset addXmlNode(xmlDoc, "time","#form.time#") >

This was more what I meant, bit less complicated, a bit more efficient...

<cfsavecontent variable="event">

</cfif>

just a note, you can reduce a bit more on what I'd shown; I was being a little lazy and used expandpath() everywhere, if you just set a variable to define the path once, its a bit better than using it multiple times, just less method calls...

<!--- Populate values in cfxml with the variables you wish --->
<cfsavecontent variable="event">
