Question

我正在使用groovy，所以java实现也没关系。

我有

"""<TextFlow fontFamily="Arial" fontSize="20"><span>before</span>Less than 7 days<span>after</span></TextFlow>"""

我想用标记包装第一级文本节点。所以我想得到

"""<TextFlow fontFamily="Arial" fontSize="20"><span>before</span><span>Less than 7 days</span><span>after</span></TextFlow>"""

我已经研究过不处理文本节点的XmlSlurper。我也研究了可以处理文本节点的XmlParser，但我不知道如何用xml元素替换它。请指教。

这对我有用，希望它能帮助别人

@Grab('org.jdom:jdom2:2.0.5')
@Grab('jaxen:jaxen:1.1.4')
@GrabExclude('jdom:jdom')

import org.jdom2.*
import org.jdom2.input.*
import org.jdom2.xpath.*
import org.jdom2.output.*

def xml = """<TextFlow fontFamily="Arial" fontSize="20"><span>before</span>Less than 7 days<span>after</span></TextFlow>"""

Document doc = new SAXBuilder().build(new StringReader(xml)) 
def urls = XPathFactory.instance().compile('//TextFlow/text()').evaluate(doc)

for(def c in urls) {
    int pos = c.parent.content.indexOf(c)    
    Element span = new Element("span")
    span.text = c.text
    c.parent.setContent(pos, span)

}

new XMLOutputter().with {
  format = Format.getRawFormat()
  format.setLineSeparator(LineSeparator.NONE)
  // XmlOutputter can write to OutputStream or Writer, which is sufficient for most cases
  output(doc, System.out)
}

用元素节点替换XML文本节点
