I have already added a Xpath extractor into the sampler:
Reference name: mytest
XPath Query: //test[#id='1']
But the return variable (mytest) is wrong.
OUT.println(mytest) --> void
I'm a newbie with JMeter. What can I do to solve this?
I have already added a Xpath extractor
into the sampler:
Reference name: mytest XPath Query:
//test[#id='1']
But the return variable (mytest) is
wrong.
OUT.println(mytest) --> void
Obviously the println() function prints the string value of the test element, and in the provided XML document test elements do not have any content and their string value is the empty string.
You want:
/*/*/test[#id=1]/#name
and
/*/*/test[#id=1]/#status
The former selects all name attributes of all test grandchildren of the top element of the document, that have an id attribute with value 1.
The latter selects all status attributes of all test grandchildren of the top element of the document, that have an id attribute with value 1.
It could be because you have no text content. Try setting "Return entire XPath fragment instead of text content?"

When I make the following AppleScript call to my app, I get a list of text objects:
tell "MyApp"
name of every myobject
end tell
But the following call returns an error:
tell "MyApp"
name of selected myobjects
end tell
Script Error
MyApp got an error: Can't make name of selected MyObjects into type specifier.
I turned on verbose logging with the -NSScriptingDebugLogLevel 1 argument to my app, which gave me this:
2015-01-27 14:33:53.650 MyApp[4848:2572448] Error converting apple event to script command: -1700

2015-01-27 14:33:53.651 MyApp[4848:2572448] Expected type descriptor: <NSAppleEventDescriptor: 'obj '>
This is the "application" section of my sdef file:
<class name="application" code="capp" plural="applications" inherits="application">
<cocoa class="MyApp.MAApplication" />
<element type="myobject" access="r">
<cocoa key="myobjects" />
</element>
<property name="selected myobjects" code="MASM">
<cocoa key="selectedMyObjects" />
<type type="myobject" list="yes" />
</property>
</class>
And the MyObject class:
<class name="myobject" code="MAMO" inherits="item" plural="myobjects">
<cocoa class="MyObject" />
<property name="id" code="ID " type="text" access="r">
<cocoa key="permanentID" />
</property>
<property name="name" code="pnam" type="text" access="r">
<cocoa key="displayName" />
</property>
</class>
When I just call selected myobjects, I get back a list of identifiers, so that part is working correctly. When can't I get the name or other properties back from that list, when I can with another list specified the exact same way (except as an element instead of property)?
Update
Still not having any luck so far. I noticed, with verbose logging, that when I call name of every MyObject, the command "Intrinsics.get" triggers with an NSPropertySpecifier "displayName of myobjects". Apparently that link doesn't get made when using a property rather than an element to return a list of items. I found a workaround, though, since I specify an is selected property on MyObject. You can call:
name of every myobject whose is selected = true
That works the way I expected my selected myobjects property to work, returning a list of text objects.
Update 2
I added a sample project to GitHub:
https://github.com/abbeycode/AppleScriptObjectList
That contains a sample script with the first two methods that behave as expected, followed by the one that triggers the error. Feel free to mess around if you'd like. I submitted a radar with this sample project.
I want to see if a theme element exists with specified name in the following xml file.
input.xml
<data>
<artifacts>
<document id="efqw4eads">
<name>composite</name>
</document>
<theme id="1">
<name>Terrace</name>
</theme>
<theme id="2">
<name>Garage</name>
</theme>
<theme id="3">
<name>Reception</name>
</theme>
<theme id="4">
<name>Grade II</name>
</theme>
</artifacts>
</data>
I have the following code. return true statement of the method is never executed. answer always contains a null value.
public boolean themeExists(String name, Data data){
String expression = "artifacts/theme[name='"+name+"']/name/text()";
String answer = jaxbContext.getValueByXPath(data, expression, null, String.class);
if(answer == null || answer.equals("")){
return false;
}
return true;
}
This use case isn't currently supported by EclipseLink JAXB (MOXy). I have opened the following enhancement you can use to track our progress:
http://bugs.eclipse.org/413823
There is no <artifacts/> element you're look for in the first axis step. Your XPath expression should be something like
String expression = "data/theme[name='"+name+"']/name/text()";
I have some XML where I know an attribute (in my case an ID#). I can get the node I'm looking for using //*[#id='v6969482']. But isn't there a way to tell me the name of this id? (I'm trying to have it return 'title' or , in my case. I know it has to do with using name(), but I can't seem to get the right syntax of returning the name when I have the id attribute.
<?xml version="1.0" encoding="UTF-8"?>
<topic id="v6969481">
<title id="v6969482">CR - ASE | AXX2500>Engines>EIOA>EIOAn>GMACn>Ingress</title>
<body id="v6969483">
<p id="v6969484">
<table id="v6153057" frame="all" colsep="1" rowsep="1">
<desc id="v6049915">Global ingress attributes for EIOA engine GMAC ports.</desc>
You need the name of the parent node of the attribute, its parent element:
name(//*[#id='v6969482'])
I have inherited an application that parses xml using dom4j and xPath:
The xml being parsed is similar to the following:
<cache>
<content>
<transaction>
<page>
<widget name="PAGE_ID">WRK_REGISTRATION</widget>
<widget name="TRANS_DETAIL_ID">77145</widget>
<widget name="GRD_ERRORS" />
</page>
<page>
<widget name="PAGE_ID">WRK_REGISTRATION</widget>
<widget name="TRANS_DETAIL_ID">77147</widget>
<widget name="GRD_ERRORS" />
</page>
<page>
<widget name="PAGE_ID">WRK_PROCESSING</widget>
<widget name="TRANS_DETAIL_ID">77152</widget>
<widget name="GRD_ERRORS" />
</page>
</transaction>
</content>
</cache>
Individual Nodes are being searched using the following:
String xPathToGridErrorNode = "//cache/content/transaction/page/widget[#name='PAGE_ID'][text()='WRK_DNA_REGISTRATION']/../widget[#name='TRANS_DETAIL_ID'][text()='77147']/../widget[#name='GRD_ERRORS_TEMP']";
org.dom4j.Element root = null;
SAXReader reader = new SAXReader();
Document document = reader.read(new BufferedInputStream(new ByteArrayInputStream(xmlToParse.getBytes())));
root = document.getRootElement();
Node gridNode = root.selectSingleNode(xPathToGridErrorNode);
where xmlToParse is a String of xml similar to the excerpt provided above.
The code is trying to obtain the GRD_ERROR node for the page with the PAGE_ID and TRANS_DETAIL_ID provided in the xPath.
I am seeing an intermittent (~1-2%) failure (returned node is null) of this selectSingleNode request even though the requested node is in the xml being searched.
I know there are some gotchas associated with using text()= in xPath and was wondering if there was a better way to format the xPath string for this type of search.
From your snippets, there is a problem regarding GRD_ERRORS vs. GRD_ERRORS_TMP and WRK_REGISTRATION vs. WRK_DNA_REGISTRATION.
Ignoring that, I would suggest to rewrite
//cache/content/transaction/page
/widget[#name='PAGE_ID'][text()='WRK_DNA_REGISTRATION']
/../widget[#name='TRANS_DETAIL_ID'][text()='77147']
/../widget[#name='GRD_ERRORS_TEMP']
as
//cache/content/transaction/page
[widget[#name='PAGE_ID'][text()='WRK_REGISTRATION']]
[widget[#name='TRANS_DETAIL_ID'][text()='77147']]
/widget[#name='GRD_ERRORS']
Just because it makes the code, in my eyes, easier to read, and expresses what you seem to mean more clearly: “the page element that has children with these conditions, and then take the widget with this #name.” Or, if that is closer to how you think about it,
//cache/content/transaction/page/widget[#name='GRD_ERRORS']
[preceding-sibling::widget[#name='PAGE_ID'][text()='WRK_REGISTRATION']]
[preceding-sibling::widget[#name='TRANS_DETAIL_ID'][text()='77147']]

If I back out the query one level, it totally strips out the element, which I could also use to get the data I need.
We have a new html parser that recognizes custom attributes now.
Add compat="html5" to trigger the new parser.
e.g.:
select * from html where url = "http://mydomain.com" and compat="html5"
