replace XmlSlurper tag with arbitrary XML
I am trying to replace specific XmlSlurper tags with arbitrary XML strings. The best way I have managed to come up with to do this is:
#!/usr/bin/env groovy
import groovy.xml.StreamingMarkupBuilder
def page=new XmlSlurper(new org.cyberneko.html.parsers.SAXParser()).parseText("""
<html>
<head></head>
<body>
<one attr1='val1'>asdf</one>
<two />
<replacemewithxml />
</body>
</html>
""".trim())
import groovy.xml.XmlUtil
def closure
closure={ bind,node->
if (node.name()=="REPLACEMEWITHXML") {
bind.mkp.yieldUnescaped "<replacementxml>sometext</replacementxml>"
} else {
bind."${node.name()}"(node.attributes()) {
mkp.yield node.text()
node.children().each { child->
closure(bind,child)
}
}
}
}
println XmlUtil.serialize(
new StreamingMarkupBuilder().bind { bind->
closure(bind,page)
}
)
However, the only problem is the text() element seems to capture all child text nodes, and thus I get:
<?xml version="1.0" encoding="UTF-8"?>
<HTML>asdf<HEAD/>
<BODY>asdf<ONE attr1="val1">asdf</ONE>
<TWO/>
<replacementxml>so开发者_高级运维metext</replacementxml>
</BODY>
</HTML>
Any ideas/help much appreciated.
Thank you! Misha
p.s. Also, out of curiosity, if I change the above to the "Groovier" notation as follows, the groovy compiler thinks I am trying to access the ${node.name()} member of my test class. Is there a way to specify this is not the case while still not passing the actual builder object? Thank you! :)
def closure
closure={ node->
if (node.name()=="REPLACEMEWITHXML") {
mkp.yieldUnescaped "<replacementxml>sometext</replacementxml>"
} else {
"${node.name()}"(node.attributes()) {
mkp.yield node.text()
node.children().each { child->
closure(child)
}
}
}
}
println XmlUtil.serialize(
new StreamingMarkupBuilder().bind {
closure(page)
}
)
Ok here is what I came up with:
#!/usr/bin/env groovy
import groovy.xml.StreamingMarkupBuilder
import groovy.xml.XmlUtil
def printSlurper={page->
println XmlUtil.serialize(
new StreamingMarkupBuilder().bind { bind->
mkp.yield page
}
)
}
def saxParser=new org.cyberneko.html.parsers.SAXParser()
saxParser.setFeature('http://xml.org/sax/features/namespaces',false)
saxParser.setFeature("http://cyberneko.org/html/features/balance-tags/document-fragment",true)
def string="TEST"
def middleClosureHelper={ builder->
builder."${string}" {
mkp.yieldUnescaped "<inner>XML</inner>"
}
}
def middleClosure={
MiddleClosure {
middleClosureHelper(delegate)
}
}
def original=new XmlSlurper(saxParser).parseText("""
<original>
<middle>
</middle>
</original>
""")
original.depthFirst().find { it.name()=='MIDDLE' }.replaceNode { node->
mkp.yield middleClosure
}
printSlurper(original)
assert original.depthFirst().find { it.name()=='INNER' } == null
def modified=new XmlSlurper(saxParser).parseText(new StreamingMarkupBuilder().bind {mkp.yield original}.toString())
assert modified.depthFirst().find { it.name()=='INNER' } != null
You have to reload the slurper, but it works!
