尝试从XML代码中提取两个用户输入。
我将数据读入数据框，其中一列包含XML。
它抱怨说它不是XML
这是第一个
shpt$t <- '<form><text id="UserText1" label="Please provide your current URL or a proposed title for your docshare site:" mandatory="true" multiline="false" readonly="false" visible="true"> http://docshare.net/org/bo/BOP/RTSupDocLibrary/eample.xlsx</text><text id="UserTextArea1" label="Provide details of the assistance you need:" mandatory="false" multiline="true" readonly="false" visible="true">Hello, Would like assistance in creating a DocShare site for our group. Thank you. </text></form>'
doc = xmlInternalTreeParse("shpt$t")
Error: XML content does not seem to be XML: 'shpt$t'
因此，我试图对匹配进行模式匹配以使其正确，但是我认为这不是正确的方法。
test <- sub(".*true *(.*?) *text.*", "\\1", shpt$t)
shpt$v1 <- gsub("\">|</", "", test)
我预期的结果是另外两个变量
shpt$v1 <- "http://docshare.net/org/bo/BOP/RTSupDocLibrary/eample.xlsx"
shpt$v2 <- "Hello, Would like assistance in creating a DocShare site for our group. Thank you."
