节点属性修改程序显示异常.. [英] Node attribute modification program showing exception..
本文介绍了节点属性修改程序显示异常..的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试创建一个程序，它将以< disp-formula id =deqnX-Y> 的形式搜索xml文件中的节点，创建一个字典，其中键是 rid =deqnX... rid =deqnY，（其中 X 增加+1，直到达到 Y ），它们各自的值对应就像 rid =deqnX-Y每个，然后我可以简单地进行搜索并使用字典替换以更改链接节点。即如果文件具有< disp-formula id =deqn5-7>，< disp-formula id =deqn9-10>，< disp-formula id = deqn3a-3c>，< disp-formula id =deqn4p-5b> 并且表格中有链接节点
< xref ref-type = disp -formula rid = deqn5 >
< xref ref-type = disp-formula rid = deqn6 >
< xref ref-type = disp-formula rid = deqn10 >
< xref ref-type = disp-formula rid = deqn5c <跨越ss =code-keyword>>
他们应该更改为
< xref ref-type = disp-formula rid = < span class =code-keyword> deqn5-7 >
< xref ref-type < span class =code-keyword> = disp-formula rid = deqn5-7 >
< xref ref-type = disp-formula rid = deqn9-10 >
< xref ref-type = disp-formula rid = deqn4p-5b >
我还希望程序忽略< disp-formula id =deqn5-7c> an d /或< disp-formula id =deqn2a-4> 在文件中。
我现在使用以下代码
我尝试过：
void Button1Click（ object sender，EventArgs e）
{
string active_filename = ;
尝试
{
string [] path = Directory.GetDirectories （textBox1.Text， xml，SearchOption.AllDirectories）
.SelectMany（x = > Directory.GetFiles（x， * .xml ，SearchOption.AllDirectories））。ToArray（）;
Dictionary< string，string> dict = new 字典< string，string>（）;
// var re = new Regex（@deqn（\d +） - （\d +） ）;
var re = new 正则表达式（ deqn（？:(？< match1> \\\\ +） - （？< match2> \\d +）| （小于MATCH1> \\d + \\w +） - （小于？MATCH2> \\d + \\w +））\\b）;
foreach （ var 文件 in 路径）
{
dict.Clear（）;
active_filename = file;
XDocument doc = XDocument.Load（file，LoadOptions.PreserveWhitespace）;
IEnumerable< XAttribute> list_of_elements = doc.Descendants（ disp-formula）。其中（z = > （z.Attribute（ id）！= null ）&& re.IsMatch（z.Attribute（ id）。值））。属性（ id）;
foreach （XAttribute ele in list_of_elements）
{
if （Regex.IsMatch（re.Match（ele.Value）.Groups [ match1]。值， @ ^ \d + $ ）&& Regex.IsMatch（re.Match（ele.Value）.Groups [ match2]。值， @ ^ \d + $））
{
var 来自 = int .Parse （re.Match（ele.Value）.Groups [ match1]。Value）;
var to = int .Parse（re.Match（ele.Value）.Groups [ match2]。Value）;
for （ int i = 来自; i < = to; i ++）
dict.Add（ rid = \deqn + i + \ ， rid = \ + ele.Value + \）;
}
if （Regex.IsMatch（re.Match（ele.Value）.Groups [ match1]。值， @ ^ \d + [az] $）&& Regex.IsMatch（re.Match（ele.Value）.Groups [ < span class =code-string> match2]。值， @ ^ \d + [ az] $））
{
var 来自 = re.Match（ele.Value）.Groups [ match1]。值;
var to = re.Match（ele.Value）.Groups [ MATCH2\" ]值。
char startCharacter = 来自 .Substring（ from .Length - 1 ）[ 0 ];
char endCharacter = to.Substring（to.Length - 1 ）[ 0 ];
int startNumber = int .Parse（ from .Substring（ 0 ，来自 .Length - 1 ））;
int endNumber = int .Parse（to.Substring（ 0 ，to.Length - 1 ））;
string alphabet = abcdefghijklmnopqrstuvwxyz;
for （ int i = startNumber; i < = endNumber; ++ i）
{
int currentCharEnd =
（i == endNumber）？ alphabet.IndexOf（endCharacter）：alphabet.Length - 1 ;
for （ int j = alphabet.IndexOf（startCharacter）; j < = currentCharEnd; ++ j）
{
dict.Add（ rid = \deqn + i.ToString（）+ alphabet [j] + \，
rid = \deqn + 来自 .ToString（）+ - + to.ToString（）+ \）;
}
startCharacter = ' a';
}
}
foreach （KeyValuePair< string，string> element in dict）
{
string text = File.ReadAllText（file）;
text = text.Replace（element.Key，element.Value）;
File.WriteAllText（file，text）;
}
}
}
MessageBox.Show（ 完成 ）;
}
catch （例外情况）
{
MessageBox.Show（ string .Format（ @ 文件中的错误（{0}），下面是调试详细信息：{1}，active_filename，ex.StackTrace.ToString（）））;
}
}
它有效，但有时显示异常，我无法弄清楚如何修复

I'm trying to create a program which will search the xml files for nodes in the form <disp-formula id="deqnX-Y">, create a dictionary where key's are like rid="deqnX" ... rid="deqnY", (where X is incremented by +1 till it reaches Y) and their respective value counterparts are like rid="deqnX-Y" each, Then I can simply do a search and replace using the dictionary to change the link nodes. i.e. if the file has nodes like <disp-formula id="deqn5-7">, <disp-formula id="deqn9-10">, <disp-formula id="deqn3a-3c">, <disp-formula id="deqn4p-5b"> and there are link nodes in the form
<xref ref-type="disp-formula" rid="deqn5">
<xref ref-type="disp-formula" rid="deqn6">
<xref ref-type="disp-formula" rid="deqn10">
<xref ref-type="disp-formula" rid="deqn5c">
they should be changed to
<xref ref-type="disp-formula" rid="deqn5-7">
<xref ref-type="disp-formula" rid="deqn5-7">
<xref ref-type="disp-formula" rid="deqn9-10">
<xref ref-type="disp-formula" rid="deqn4p-5b">
I also want the program to ignore nodes like <disp-formula id="deqn5-7c"> and/or <disp-formula id="deqn2a-4"> in the file.
I'm using the below code for now
What I have tried:
void Button1Click(object sender, EventArgs e)
{
string active_filename = "";
try
{
string[] path = Directory.GetDirectories(textBox1.Text, "xml", SearchOption.AllDirectories)
.SelectMany(x => Directory.GetFiles(x, "*.xml", SearchOption.AllDirectories)).ToArray();
Dictionary<string, string> dict = new Dictionary<string, string>();
//var re = new Regex(@"deqn(\d+)-(\d+)");
var re=new Regex("deqn(?:(?<match1>\\d+)-(?<match2>\\d+)|(?<match1>\\d+\\w+)-(?<match2>\\d+\\w+))\\b");
foreach (var file in path)
{
dict.Clear();
active_filename = file;
XDocument doc = XDocument.Load(file, LoadOptions.PreserveWhitespace);
IEnumerable<XAttribute> list_of_elements = doc.Descendants("disp-formula").Where(z => (z.Attribute("id") != null) && re.IsMatch(z.Attribute("id").Value)).Attributes("id");
foreach (XAttribute ele in list_of_elements)
{
if (Regex.IsMatch(re.Match(ele.Value).Groups["match1"].Value, @"^\d+$") && Regex.IsMatch(re.Match(ele.Value).Groups["match2"].Value, @"^\d+$"))
{
var from = int.Parse(re.Match(ele.Value).Groups["match1"].Value);
var to = int.Parse(re.Match(ele.Value).Groups["match2"].Value);
for (int i = from; i <= to; i++)
dict.Add("rid=\"deqn" + i + "\"", "rid=\"" + ele.Value + "\"");
}
if (Regex.IsMatch(re.Match(ele.Value).Groups["match1"].Value, @"^\d+[a-z]$") && Regex.IsMatch(re.Match(ele.Value).Groups["match2"].Value, @"^\d+[a-z]$"))
{
var from = re.Match(ele.Value).Groups["match1"].Value;
var to = re.Match(ele.Value).Groups["match2"].Value;
char startCharacter = from.Substring(from.Length - 1)[0];
char endCharacter = to.Substring(to.Length - 1)[0];
int startNumber = int.Parse(from.Substring(0, from.Length - 1));
int endNumber = int.Parse(to.Substring(0, to.Length - 1));
string alphabet = "abcdefghijklmnopqrstuvwxyz";
for (int i = startNumber; i <= endNumber; ++i)
{
int currentCharEnd =
(i == endNumber) ? alphabet.IndexOf(endCharacter) : alphabet.Length - 1;
for (int j = alphabet.IndexOf(startCharacter); j <= currentCharEnd; ++j)
{
dict.Add("rid=\"deqn" + i.ToString() + alphabet[j] + "\"",
"rid=\"deqn" + from.ToString() + "-" + to.ToString() + "\"");
}
startCharacter = 'a';
}
}
foreach (KeyValuePair<string, string> element in dict)
{
string text = File.ReadAllText(file);
text = text.Replace(element.Key, element.Value);
File.WriteAllText(file, text);
}
}
}
MessageBox.Show("Done");
}
catch (Exception ex)
{
MessageBox.Show(string.Format(@"Error in file ({0}), below are the debug details: {1}", active_filename, ex.StackTrace.ToString()));
}
}
It works but sometimes shows an exception that I can't figure out how to fix
