I have an xml file that I want to read using VBScript (Technology limitation). Below is the code and xml file. I am able to read the file if there is no DTD element involved but the code doesn't work for file having DTD and xml-style element.
Code-
Dim xmlDoc1:Set xmlDoc1 = CreateObject("MSXML2.DomDocument")
xmlDoc1.async=False
xmlDoc1.load "C:\ABC.xml"
Dim xmlTCID:Set xmlTCID = xmlDoc1.selectNodes("//*")
For nNodeCount = 0 To xmlTCID.length
MsgBox(xmlTCID(nNodeCount).nodeName)
Next
ABC.xml -
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE RESULT SYSTEM "Result.dtd"[]>
<?xml-stylesheet type="text/xsl" href="Result.xsl"?>
<SUMMARY>
<TITLE>Test</TITLE>
</SUMMARY>
<IDS>
<DATA>
<NAME>A</NAME>
<VALUE>PASS</VALUE>
</DATA>
<DATA>
<NAME>B</NAME>
<VALUE>PASS</VALUE>
</DATA
<DATA>
<NAME>C</NAME>
<VALUE>FAIL</VALUE>
</DATA
</IDS>
<IDS>
<DATA>
<NAME>A</NAME>
<VALUE>PASS</VALUE>
</DATA>
<DATA>
<NAME>B</NAME>
<VALUE>FAIL</VALUE>
</DATA
</IDS>
Note - If I avoid -
<!DOCTYPE RESULT SYSTEM "Result.dtd"[]>
<?xml-stylesheet type="text/xsl" href="Result.xsl"?>
The above code is able to read the nodes but with the above two lines in xml file, it gives the below error -
Requirement - I need to read the name of last DATA node with FAIL for each IDS node.
Any suggestion as what to do to get the code working even with -
<!DOCTYPE RESULT SYSTEM "Result.dtd"[]>
<?xml-stylesheet type="text/xsl" href="Result.xsl"?>
As there are problems with your XML - more than one top level element, miising ">" - setting the ProhibitDTD Property to False won't solve all of your tasks.
xmlDoc.validateOnParse=False
worked for me.

I am making a SOAP webservice call and I get the below response. I want to read the value in internal XML, the value is 12345684 in 1234684 in the below XML.
I was able to get internal XML using #[xpath3('//:processaResponse /return[2]')], store it in a flow variable and #[xpath3('/AckReg/DataArea/PRegistration/PRDet/Person/IDSet/:ID[#schemeName="aid"]/text()')].
This works when I try an online parser, but it doesn't read the value in Mule.
Is there any way to extract 1234684 in oa:ID tag using one XPath.

In your expressions you were missing namespace prefixes or namespace wildcards *: on some nodes - so your expressions failed.
Is there any way to extract 1234684 in oa:ID tag using one XPath.
Combining both of your partial expressions is possible with namespace wildcards:
//*:processaResponse/return[2]/*:AckReg/*:DataArea/*:PRegistration/*:testids/*:IDSet/*:ID[#schemeName='abcid']/text()
Or you can use an absolute path with namespace wildcards:
/*:Envelope/*:Body/*:processaResponse/return[2]/*:AckReg/*:DataArea/*:PRegistration/*:testids/*:IDSet/*:ID[#schemeName='abcid']/text()
Output in both cases:
1234684
You can even use XmlSlurper class using groovy script to fetch that respective value.
root = new XmlSlurper( false, true).parseText(payload).declareNamespace('soapenv':"http://schemas.xmlsoap.org/soap/envelope/")
Im getting below error, can anyone please help me resolve it.

From Oracle Documentation.
PL/SQL package DBMS_XSLPROCESSOR provides a convenient and efficient
way of applying a single style sheet to multiple documents. The
performance of this package is better than that of method transform(),
because the style sheet is parsed only once.
I had the same problem. Workaround was. Something like this.

I am having problems understanding Net::HTTP and Nokogiri.
I have a large number of jobs on my Jenkins server. I have to periodically update the branch name on these jobs. Doing it from the UI is a cumbersome process so I decided to update the Jenkins config.xml.
I use Nokogiri to parse the XML, traverse the XPath and update the value of the node. However, when I try to post the updated XML back to Jenkins, I get a 500 error saying:
Caused by: javax.xml.transform.TransformerException: org.xml.sax.SAXParseExceptionpublicId: -//W3C//DTD HTML 4.0 Transitional//EN; systemId: http://www.w3.org/TR/REC-html40/loose.dtd; lineNumber: 31; columnNumber: 3; The declaration for the entity "HTML.Version" must end with '>'.
Here is what I am doing:
require "net/http"
require "nokogiri"
uri = URI.parse("http://jenkins.my.domain.web:8080")
http = Net::HTTP.new(uri.host, uri.port)
getQueueRequest = Net::HTTP::Get.new("http://jenkins.my.domain.web:8080/my/job/location/config.xml")
getQueue = http.request(getQueueRequest)
xml_doc = Nokogiri::HTML(getQueue.body)
# Get current branch name
branch_name=xml_doc.at_xpath('//hudson.plugins.git.branchspec/name')
# Get new branch name
print "Enter new branch name "
user_input = gets.chomp
new_branch_name = user_input.downcase
# Set branch name and create xml
branch_name.content=new_branch_name
new_config_xml=xml_doc.to_xml
puts "Logging into Jenkins"
update_branch = Net::HTTP::Post.new("http://jenkins.my.domain.web:8080/my/job/location/config.xml")
update_branch.basic_auth 'username', 'password'
update_branch.body = new_config_xml
response = http.request(update_branch)
puts response.body
I understand it might have to do something with the XML that is getting added to request body but I am not sure how to fix the issue.

When you use Nokogiri::HTML(some_html) or Nokogiri::XML(some_xml), Nokogiri will look to see if the content is valid. If it isn't, it will do fix-ups on the content in an attempt to make it so. For instance:
require 'nokogiri'
html_fragment = "<p>foo bar</p>"
Nokogiri::HTML(html_fragment).to_html
# => "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n<html><body><p>foo bar</p></body></html>\n"
If the document is partially correct Nokogiri still adds the DOCTYPE statement:
html = "<html><body><p>foo bar</p></body></html>"
Nokogiri::HTML(html).to_html
# => "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n<html><body><p>foo bar</p></body></html>\n"
If you want Nokogiri to leave the document along, because it's supposed to be a fragment, tell it to do so:
Nokogiri::HTML::DocumentFragment.parse(html_fragment).to_html
# => "<p>foo bar</p>"
Or:
xml_fragment = "<x>foo bar</x>"
Nokogiri::XML::DocumentFragment.parse(xml_fragment).to_xml
# => "<x>foo bar</x>"
Nokogiri is pretty smart about handling XML and HTML. You can try to confuse it and it'll generally do the right thing:
xml_fragment = "<x>foo bar</x>"
Nokogiri::HTML::DocumentFragment.parse(xml_fragment).to_xml
# => "<x>foo bar</x>"
That's parsing XML as an HTML fragment and telling it to emit it as XML.
Now, that all said, it's pretty obvious Nokogiri isn't doing anything mysterious, so, here's how to fix the problem. First, parse it as XML so Nokogiri doesn't think it should add the HTML DOCTYPE declaration, then, if the XML is syntactically correct, tell Nokogiri it's OK to parse it as a complete document:
require 'nokogiri'
xml = %{<?xml version='1.0' encoding='UTF-8'?>
<maven2-moduleset plugin="maven-plugin#1.504">
<actions/>
<description></description>
<keepDependencies>false</keepDependencies>
<properties>
<hudson.plugins.throttleconcurrents.ThrottleJobProperty plugin="throttle-concurrents#1.7.2">
</hudson.plugins.throttleconcurrents.ThrottleJobProperty>
</properties>
</maven2-moduleset>
}
puts Nokogiri::XML.parse(xml).to_xml
# >> <?xml version="1.0" encoding="UTF-8"?>
# >> <maven2-moduleset plugin="maven-plugin#1.504">
# >> <actions/>
# >> <description/>
# >> <keepDependencies>false</keepDependencies>
# >> <properties>
# >> <hudson.plugins.throttleconcurrents.ThrottleJobProperty plugin="throttle-concurrents#1.7.2">
# >> </hudson.plugins.throttleconcurrents.ThrottleJobProperty>
# >> </properties>
# >> </maven2-moduleset>
Or as a fragment, which, because it's complete, will result in the same thing:
puts Nokogiri::XML::DocumentFragment.parse(xml).to_xml
# >> <?xml version='1.0' encoding='UTF-8'?>
# >> <maven2-moduleset plugin="maven-plugin#1.504">
# >> <actions/>
# >> <description/>
# >> <keepDependencies>false</keepDependencies>
# >> <properties>
# >> <hudson.plugins.throttleconcurrents.ThrottleJobProperty plugin="throttle-concurrents#1.7.2">
# >> </hudson.plugins.throttleconcurrents.ThrottleJobProperty>
# >> </properties>
# >> </maven2-moduleset>
Instead of using Net::HTTP, which is the bare-building blocks for HTTP, I'd recommend looking at something a bit higher-level, like HTTPClient. Here's code that is similar to yours:
require 'httpclient'
require 'nokogiri'
URL = 'http://jenkins.my.domain.web:8080/my/job/location/config.xml'
http_client = HTTPClient.new
xml_doc = Nokogiri::HTML(
http_client.get_content(URL)
)
# Get current branch name using CSS for simplicity:
branch_name = xml_doc.at('hudson.plugins.git.branchspec name')
# Get new branch name
print 'Enter new branch name '
new_branch_name = gets.chomp.downcase
# Set branch name and create xml
branch_name.content = new_branch_name
puts 'Logging into Jenkins'
http_client.set_auth(domain, 'user', 'password')
response = http_client.post(URL, :body => xml_doc.to_xml)
I can't test it but it looks close.
I, now, find myself in another dilemma. I am seeing that the methods which allow moving to elements and editing values like at_xpath, at_css only work with Nokogiri::HTML or Nokogiri::HTML::DocumentFragment. They don't work when I use Nokogiri::XML. Using Nokogiri::HTML changes the case of the HTML tags. false becomes false. Jenkins does accept the xml with changed case of tags. Methods to_html, to_xml basically returns a string so I cannot use the xpath or css methods to navigate the xml tree. Is there a way around ?
The at methods work with both XML and HTML, and allows CSS and XPath selectors; Everything inside Nokogiri is really XML-based.
Nokogiri folds HTML tags to lower-case because HTML is case-insensitive, so at expects a lower-case value when dealing with HTML. XML is case-sensitive, so Nokogiri leaves the tag case alone, and at requires you to use the correct case when using CSS.
This is documented in the Nokogiri docs:
Note that the CSS query string is case-sensitive with regards to your document type. That is, if you’re looking for “H1” in an HTML document, you’ll never find anything, since HTML tags will match only lowercase CSS queries. However, “H1” might be found in an XML document, where tags names are case-sensitive (e.g., “H1” is distinct from “h1”).
When you are parsing the XML you are receiving from the service, you are declaring it as HTML:
xml_doc = Nokogiri::HTML(getQueue.body)
And this appears to cause Nokogiri to add HTML nodes.
Try parsing it as XML instead:
xml_doc = Nokogiri::XML(getQueue.body)
I am trying to down my last 3200 tweets in groups of 200(in multiple pages) using restclient gem.
In the process, I end up adding the following lines multiple times to my file:
</statuses>
<?xml version="1.0" encoding="UTF-8"?>
<statuses type="array">
To get this right(as the XML parsing goes for a toss), after downloading the file, I want to replace all occurrences of the above string except the first.
I am trying the following:
tweets_page = RestClient.get("#{GET_STATUSES_URL}&page=#{page_number}")
message = <<-MSG
</statuses>
<?xml version="1.0" encoding="UTF-8"?>
<statuses type="array">
MSG
unless page_number == 1
tweets_page.gsub!(message,"")
end
What is wrong in the above? Is there a better way to do the same?
I believe it would be faster to download the whole bunch at once and split the body of your response by message and add it for the first entry.
Something like this, can't try it out so consider this just as an idea.
tweets_page = RestClient.get("#{GET_STATUSES_URL}").body
tweets = tweets_page.split(message)
tweets_page = tweets[0]+message+tweets[1..-1]
You could easily break them up in groups of 200 like that also
If you want to do it with a gsub on the whole text you could use the following
tweets_page = <<-MSG
first
</statuses>
<?xml version="1.0" encoding="UTF-8"?>
<statuses type="array">
second
</statuses>
<?xml version="1.0" encoding="UTF-8"?>
<statuses type="array">
rest
MSG
message = <<-MSG
</statuses>
<?xml version="1.0" encoding="UTF-8"?>
<statuses type="array">
MSG
new_str = tweets_page.gsub message do |match|
if defined? #first
""
else
#first = true
message
end
end
p new_str
gives
type=\"array\">\nrest\n"
"first\n</statuses>\n<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<statuses type=\"array\">\nsecond\nrest\n"
I have an XML, which can be like
<?xml version="1.0" encoding="utf-8"?>
<testnode type="1">123</testnode>
or like
<?xml version="1.0" encoding="utf-8"?>
<othernode attrib="true">other value</othernode>
or the root node can be something completely unexpected. (Theoretically anything.)
I'm using REXML to parse it. How can I find out what XML node is the root element?
xml = REXML::Document.new "<?xml version" #etc (or load from file)
root_node = xml.elements[1]
root_node_name = root_node.name
