My code is
<cfxml variable="str">
<root>
<T id="1" name="jaggu"></T>
<T id="2" name="jaggu2"></T>
</root>
</cfxml>
<cfset MyXMLDoc = xmlParse(str)>
<cfset packages = xmlSearch(MyXMLDoc, '/root/T')>
<cfoutput>
#structcount(packages[1])#
</cfoutput>
I am getting 0 but there are 2 atttributes in tag T
Is there any way to get count of xmlattributes
The problem is that you're asking for the wrong information. You're asking for the number of structs in the first match, which is in fact 0. If you want the number of attributes on the T tag, you need to get the count of the xmlAttributes node, like so:
#structcount(packages[1].xmlAttributes)#

I have the following XML structure:
<itemsWithLabels>
<itemLabelValue>
<label>A</label>
<value>a</value>
</itemLabelValue>
<itemLabelValue>
<label>B</label>
<value>b</value>
</itemLabelValue>
<itemLabelValue>
<label>C</label>
<value>c</value>
</itemLabelValue>
</itemsWithLabels>
Using XSL I want to be able to get the value from <value> by knowing the label in <label>.
So my transformation looks like this:
<xsl:value-of select="$content/itemsWithLabels/itemLabelValue/value[#label='A']" />
But clearly something is wrong because I don't have any output.
What am I doing wrong?
Try:
<xsl:value-of select="$content/itemsWithLabels/itemLabelValue[label='A']/value" />
$content/itemsWithLabels/itemLabelValue[label='A'] gets itemLabelValue elements with a label element child having value A. The /value part gets the child value element.
I am needing a little help with filtering my xml based on a property
I have the XML in the following format:
<?xml version="1.0" encoding="utf-8" ?>
<root id="-1">
<LandingPage id="1067" parentID="1050" level="2"
writerID="0" creatorID="0" nodeType="1066" template="1073"
sortOrder="0" createDate="2013-02-04T14:29:39"
updateDate="2013-02-07T11:08:27" nodeName="About"
urlName="about" writerName="Pete" creatorName="Pete"
path="-1,1050,1067" isDoc="">
<hideInNavigation>0</hideInNavigation>
</LandingPage>
</root>
What I need to do is filter these elements where hideInNavigation = 0
I have tried the following:
[#isDoc and #hideInNavigation ='0']
(I need the #isDoc attribute too) but realised this would only work if hideInNavigation was an attribute of the LandingPage tag so I tried
value['hideInNavigation'='0']
but this didn't seem to do anything either. After much searching for the answer, I haven't come up with anything so was wondering if it is possible
Supposing the current context was the <root> element, you could select the LandingPages with hideInNavigation = 0 with:
LandingPage[hideInNavigation = '0']
If you would share your XSLT, I van give you more specific guidance on how to amend it for this particular case.
And was the #isDoc test in your first example something you wanted? Do you want to filter LandingPages that have an isDoc attribute and a hideInNavigation value of 0?
'hideInNavigation'='0' compares the two strings 'hideInNavigation' and '0', which are guaranteed to be different.
In the context of root, LandingPage[hideInNavigation=0] would match the LandingPage element in your example.
This XPath return all LandingPage with isDoc attribute empty and hideInNavigation element content is '0'
//LandingPage[#isDoc="" and hideInNavigation='0']
I would like to limit the x-axis of my chart that is created by cfchart. I see the attribute scaleFrom and scaleTo that limit the y-axis, but I see nothing that limits the x-axis.
Also, I saw a similar question here:
ColdFusion Chart x-axis label limits
but neither of the answers were appropriate. ScaleMin and ScaleMax do not exists as far as I can tell and the other answer is more complicated than what I'd like to do.
The scaleMin and scaleMax attributes Saul mentioned are only available when using a custom style. Note, using type "scale" means your xAxis values must be numeric. If you want to use strings, you will probably need to use Ben's approach instead.
Here is a quick example that creates a chart with 24 points on the xAxis. Even though the query only contains the first six (6) points.
<!--- bare bones style --->
<cfsavecontent variable="style">
<?xml version="1.0" encoding="UTF-8"?>
<frameChart is3D="false" isInterpolated="true">
<frame xDepth="3" yDepth="1" />
<xAxis type="Scale" scaleMin="0" scaleMax="24" labelCount="25" isBucketed="false" />
</frameChart>
</cfsavecontent>
<!--- sample query --->
<cfset qry = queryNew("")>
<cfset queryAddColumn(qry, "xValue", listToArray("1,2,3,4,5,6"))>
<cfset queryAddColumn(qry, "yValue", listToArray("30,15,22,14,45,5"))>
<!--- chart code --->
<cfchart format="jpg" style="#style#" width="600">
<cfchartseries type="line"
markerstyle="circle"
query="qry"
itemColumn="xValue"
valueColumn="yValue" />
</cfchart>
We have in input an XML like following:
<R>
<MT N="folder" V="Folder1\Subfolder1" />
<MT N="folder" V="Folder2xx\Subfolder1" />
<MT N="folder" V="Folder3yyyy\Subfolder1" />
<MT N="folder" V="Folder4zzzz\Subfolder1" />
</R>
In our XSLT that performs the display, the entry:
<xsl:value-of select="MT[#N='folder']/#V"/>
displays:
Folder1\Subfolder1 Folder2xx\Subfolder1 Folder3yyyy\Subfolder1 Folder4zzzz\Subfolder1
What we need to achieve is to select the unique entry who starts with a pre-defined configurable list of strings, e.g. if our pre-defined list is
Folder2xx, Folder18ppp, Folder212aaa
I would like to display as output only
Folder2xx\Subfolder1
The optimal thing would be even:
Folder2xx\Subfolder1 (linked 3 times)
but I would really appreciate help on the selection of the unique element.
That is unfortunately too complex for my knowledge on XSLT, can someone please help?
Our system supports XSLT 2.0 and XPATH 2.0
thanks a lot!
Mario
Use:
MT[#N='folder']
/#V[substring-before(.,'\')
=
('Folder2xx', 'Folder18ppp', 'Folder212aaa')
]
I am fairly new to XML dev.. I had a few questions regarding XML parsing with XPATH and libxml.
I have an XML structured as :
<resultset>
<result count=1>
<row>
<name> He-Man! </name>
<home> Greyskull </home>
<row>
</result>
<result count=2>
<row>
<name> Spider-Man</name>
<home> Some downtown apartment </home>
<row>
<row>
<name> Disco-Man!</name>
<home> The 70's dance floor </home>
<row>
</result>
<resultset>
I need to pick out the names from this XML , but where the count is 2 , i need it only from the first record. I ran through a few tutorials, but i am unable to come up with an XPATH query which would serve this purpose.
/name will select all name elements.
/result[#count > 1 ]/row[1]/name | /result[#count =1 ]/row/name
Is this possible to be done with XPATH ? Is this better to be done via XPATH or by walking the XML tree?
Can some one point me to some complex searches through out XML's ?
Edit : The actual scenario requires select a subset of the XML row , which are nested at 2 levels at times. This sounds like i need to OR '|' many paths to select the nodes i require... I am not sure if that would be efficient as opposed to walking a tree... The above is typed to replicate the problem :)
Thanks!
Try this XPath -
/resultset/result[#count=2]/row/name
This will give a list of all nodes falling under this XPath. From this just take the first element (as you needed only the first record).
I'd probably keep my xpath simpler and just extract both cases, then loop over both node sets.
If you do need to go down the single xpath route, you should try out your xpath expressions in something that lets you enter them live, rather than having to recompile C/C++ code. You should be able to do that by loading your XML into firefox and using firebug - for example typing $x('//name') in the firebug console gives three nodes.
NOTE however that your XML is invalid... You have a bunch of "<row>"s that should be "</row>" and the same for "<resultset>" and your counts need to be
<result count="1">
i.e. with quote marks around the value.
