I am writing an xml exporter in ruby and I am using libxml package for it.
I want to write some comment nodes outside the root element
<?xml version="1.0" encoding="UTF-8"?>
<!-- comment -->
<root>
<childnode />
</root>
How do I accomplish export to above format?
Sample ruby code to generate the above (without accounting for comment node)
doc = XML::Document.new()
rootNode = XML::Node.new('root')
doc.root = rootNode
childNode = XML::Node.new('childnode')
childnode << rootNode
ended up editing the xml string manually to add the comments outside the root node (for both libxml and nokogiri
<?xml version="1.0" encoding="UTF-8" ?>
<List type = "" =”00:75:00” =”00:00:05”>
</List>
Yes
<?xml version="1.0" encoding="UTF-8" ?>
<List type = "update" >
</List>

I'm opening a XML file with this content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE relatos PUBLIC "-//SINCODH/DTD relatos 0.97" "relatos.dtd">
<relatos>
</relatos>
Now, I want to replace the DOCTYPE tag for a new dtd:
<!DOCTYPE relatos SYSTEM "test/dummy/public/midtd.dtd">
I'm trying with this, but seems first i need to remove dtd tag existing:
docnoko = Nokogiri::XML(doc)
docnoko.create_internal_subset("relatos", nil, "test/dummy/public/midtd.dtd")
Well, usually Nokogiri makes it really easy to replace nodes or delete them and add something else in, but this requires a bit of a work-around:
require 'nokogiri'
old_doc = Nokogiri::XML(<<EOT)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE relatos PUBLIC "-//SINCODH/DTD relatos 0.97" "relatos.dtd">
<relatos>
<foo />
<bar />
</relatos>
EOT
Create a new document:
new_doc = Nokogiri::XML('<relatos/>')
Which looks like this:
new_doc.to_xml # => "<?xml version=\"1.0\"?>\n<relatos/>\n"
Then add the new DTD:
new_doc.create_internal_subset('relatos', nil, 'test/dummy/public/midtd.dtd')
Then append the nodes from the old document to the new one:
new_doc.at('relatos').children = old_doc.at('relatos').children
Resulting in:
new_doc.to_xml # => "<?xml version=\"1.0\"?>\n<!DOCTYPE relatos SYSTEM \"test/dummy/public/midtd.dtd\">\n<relatos>\n <foo/>\n <bar/>\n</relatos>\n"
Here's the code in one chunk:
require 'nokogiri'
old_doc = Nokogiri::XML(<<EOT)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE relatos PUBLIC "-//SINCODH/DTD relatos 0.97" "relatos.dtd">
<relatos>
<foo />
<bar />
</relatos>
EOT
new_doc = Nokogiri::XML('<relatos/>')
new_doc.create_internal_subset('relatos', nil, 'test/dummy/public/midtd.dtd')
new_doc.at('relatos').children = old_doc.at('relatos').children
You might ask on the Nokogiri-Talk list or their IRC channel as the really smart people hang out there.
I need to set a selector to checkboxes that are created programatically, this way:
var cbAll = new CheckBox(Activity);
LinearLayout.LayoutParams llAll = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WrapContent, ViewGroup.LayoutParams.WrapContent);
cbAll.Text = "All zones";
llAll.LeftMargin = 27;
llAll.TopMargin = 24;
cbAll.ButtonDrawable = //what to put here?
My selector (named cb_edit.xml) in drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:tools="http://schemas.android.com/tools" xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/cb_active" android:state_checked="true" />
<item android:drawable="#drawable/cb_default" android:state_checked="false"/>
</selector>
i don't know what exactly you trying.but if u setting background then try this
cbAll.SetBackgroundResource( Resource.Drawable.cb_edit);
First, add an XML into your drawable folder:
CheckBoxDrawable.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="#drawable/CheckedImage" />
<item android:state_checked="false" android:drawable="#drawable/UnCheckedImage" />
</selector>
Then declare the checkbox and set the button drawable to it something like this:
Checkbox btnOption = new Checkbox(context);
btnOption.SetButtonDrawable(Resource.Drawable.CheckBoxDrawable);
That should make it work in case it does not revert
My question may sound stupid but I am struggling to achieve my result. I would like to edit and save version tage of vsixmanifest file without loosing any content. This article almost solved my purpose but it removes some of the tags.
<?xml version="1.0" encoding="utf-8"?>
<Vsix xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="1.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010">

Here is my gradle script
task updateExtensionManifest{
def vsixmanifestFile = "build/source.extension.vsixmanifest"
def vsixmanifest = new XmlParser().parse(vsixmanifestFile)
vsixmanifest.Identifier[0].Version[0].value="YYYYY"
def nodePrinter = new XmlNodePrinter(new PrintWriter(new FileWriter(vsixmanifestFile)))
nodePrinter.preserveWhitespace = true
nodePrinter.expandEmptyElements = true
nodePrinter.print(vsixmanifest)
}
When I execute the script it removes some of the tags defines manifest file, this is how it looks after task is getting executed:
<Vsix xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010" Version="1.0.0">

Some unwanted edits:
Line1 removed: <?xml version="1.0" encoding="utf-8"?>
Line2 modified to <Vsix xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010" Version="1.0.0">
Tag "Description" got edited too..
How could I avoid this edits? I just expected the version to get modified from XXXXX to YYYYY without changing any other content through my gradle build script.
That is because XmlNodePrinter.
If xml markup declaration is needed, use XmlUtil.serialize().
def vsixmanifest = new XmlSlurper().parse(vsixmanifestFile)
vsixmanifest.Identifier[0].Version.replaceBody ( "YYYYY" )
println groovy.xml.XmlUtil.serialize(vsixmanifest)

I have a sample XML document like
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<SearchSecretsResponse xmlns="urn:thesecretserver.com">
<SearchSecretsResult>
<Errors/>
<SecretSummaries>
<SecretSummary>
<SecretId>86</SecretId>
<SecretName>hostName\root</SecretName>
<SecretTypeName>Unix Root Account (SSH)</SecretTypeName>
</SecretSummary>
</SecretSummaries>
</SearchSecretsResult>
</SearchSecretsResponse>
</soap:Body>
</soap:Envelope>
I am trying to parse it using Nokogiri. My code is
doc = Nokogiri::XML.parse(xml)
puts doc.xpath('//SecretSummary')
But this doesn't print anything. What am I doing wrong ?
You'll need to alias the namespace.
Nokogiri::XML(xml).xpath('//foo:SecretSummary', 'foo' => 'urn:thesecretserver.com')
You could also remove the namespaces
doc.remove_namespaces!
I have an xml document like this:
<?xml version="1.0" encoding="UTF-8"?>
<foo:root xmlns:foo="http://abc.com#" xmlns:bar="http://def.com" xmlns:ex="http://ex.com">
<foo:element foo:attribute="attribute_value">
<bar:otherElement foo:otherAttribute="otherAttributeValue"/>
</foo:element>
</foo:root>
I need to add child elements to the element so that it looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<foo:root xmlns:foo="http://abc.com#" xmlns:bar="http://def.com" xmlns:ex="http://ex.com">
<foo:element foo:attribute="attribute_value">
<bar:otherElement foo:otherAttribute="otherAttributeValue"/>
<bar:otherElement foo:otherAttribute="newAttributeValue"/>
<ex:yetAnotherElement foo:otherAttribute="yetANewAttributeValue"/>
</foo:element>
</foo:root>
I can add elements in the correct location using the following:
require 'rubygems'
require 'nokogiri'
doc = Nokogiri::XML::Document.parse(File.open("myfile.xml"))
el = doc.at_xpath('//foo:element')
newEl = Nokogiri::XML::Node.new("otherElement", doc)
newEl["foo:otherAttribute"] = "newAttributeValue"
el.add_child(newEl)
newEl = Nokogiri::XML::Node.new("yetAnotherElement", doc)
newEl["foo:otherAttribute"] = "yetANewAttributeValue"
el.add_child(newEl)
However the prefix of the new elements is always "foo":
<foo:root xmlns:foo="http://abc.com#" xmlns:bar="http://def.com" xmlns:ex="http://ex.com">
<foo:element foo:attribute="attribute_value">
<bar:otherElement foo:otherAttribute="otherAttributeValue" />
<foo:otherElement foo:otherAttribute="newAttributeValue" />
<foo:yetAnotherElement foo:otherAttribute="yetANewAttributeValue" />
</foo:element>
</foo:root>
How can I set the prefix on the element name for these new child elements? Thanks,
Eoghan
(removed bit about defining namespace, orthogonal to question and fixed in edit)
just add a few lines to your code, and you get the result desired:
require 'rubygems'
require 'nokogiri'
doc = Nokogiri::XML::Document.parse(File.open("myfile.xml"))
el = doc.at_xpath('//foo:element')
newEl = Nokogiri::XML::Node.new("otherElement", doc)
newEl["foo:otherAttribute"] = "newAttributeValue"
# ADDITIONAL CODE
newEl.namespace = doc.root.namespace_definitions.find{|ns| ns.prefix=="bar"}
#
el.add_child(newEl)
newEl = Nokogiri::XML::Node.new("yetAnotherElement", doc)
newEl["foo:otherAttribute"] = "yetANewAttributeValue"
# ADDITIONAL CODE
newEl.namespace = doc.root.namespace_definitions.find{|ns| ns.prefix == "ex"}
#
el.add_child(newEl)
and the result:
<?xml version="1.0" encoding="UTF-8"?>
<foo:root xmlns:abc="http://abc.com#" xmlns:def="http://def.com" xmlns:ex="http://ex.com" xmlns:foo="http://foo.com" xmlns:bar="http://bar.com">
<foo:element foo:attribute="attribute_value">
<bar:otherElement foo:otherAttribute="otherAttributeValue"/>
<bar:otherElement foo:otherAttribute="newAttributeValue"/>
<ex:yetAnotherElement foo:otherAttribute="yetANewAttributeValue"/>
</foo:element>
</foo:root>
The namespace 'foo' is not defined.
